The Elwood line of DIN Poppet Directional Valves is a modern controls concept in water hydraulics - a line of 2-, 3- and 4-way control valves

incorporating the following features:

Zero Leakage - Positive, drop tight sealing is achieved by poppet type plunger assemblies with resilient seating discs, which close against heat treated stainless steel mitered seats.

Extended Poppet Seal Life - The dynamic seals nevercross ports during operation, therefore, cannot extrude intoports. These seals are wear compensating.

Minimal Valve Space Requirements - Compact subplate mounted design reduces space requirements by as much as 50%.

Easy Valve Maintenance - All normal maintenance can be performed from the top side of the valve without removing the valve from the system. The internals are designed eliminatingall "press" fitted as well as "selectively" locked parts orassemblies. Cavities conform to international DIN standardsand are sleeved to facilitate seal and parts replacement.

Directional Control Function Flexibility - Main controlvalve function can be changed by removing the top plate and relocating the plugs in the pilot fluid passageways.

Less Inventory Required - Because such parts aspoppets, seals, etc., are interchangeable between 2-, 3- and 4-way valves, spare parts inventory requirements are minimized. Exchanging the poppet assembly replaces all dynamic seals.

Built in Flow Controls - Totally independent "meter-in"and/or "meter-out" flow control from either port is accomplishedby simply limiting the poppet stroke by use of the externally accessible stainless steel flow control screw.

Maximum Efficiency of Fluid Flow - The design of the passage-ways through Elwood Directional Control Valves,results in outstanding valve efficiency and minimum pressure drops, allowing smaller Elwood valve size selection for most applications. Thus, it is smaller in comparison to competitive valves and requires less manifold space.

Pilot Designed to Suit Application - For heavy duty milltype applications, our standard air actuated packed spool pilot valve (Bulletin E82) is furnished. This valve requires no secondary operating media.

Six Poppet Models Available - Designed for dual speed applications. SIMPLIFIED SECTION

Features of our Poppet Directional Valves

Page 3: DIRECTIONAL CONTROL VALVES 2-, 3- AND 4-WAY DIN POPPET …

Directional Control ValveValve Sizing

Valve sizing and selection requires consideration in two (2) areas:

1) PIPE VELOCITY & PRESSURE DROP Allowable maximum pipe velocity is based on various system considerations and fluid velocity and resultant pressure drop. Generally, the following flow rates are acceptable parameters for most piping systems:

- for short-to-medium length runs, 26 feet per second (8 meters per second), and a maximum of 30 feet per second (9 meters per second). - for long piping runs, 20 feet per second (6.5 meters per second).

These parameters consider pressure drop. However, to do a complete engineering analysis, one would need to calculate the length of actual pipe runs, factoring in the number of elbows, valves, etc., to determine the system pressure drop. In this case, Cranes Referenceor other reference can be used.

2) PRESSURE DROP THROUGH THE VALVE For correct valve sizing, it is necessary to determine pressure drop through the valve. Due to the fact that not all manufacturers clearly state their valve flow characteristics, it may not seem easy to determine the pressure drop. But, it is simple when the Cv is given. The most effective method for comparing alternative valves is by the Cv factors that valve manufacturers provide for each individual valve. This enables engineers to calculate and compare pressure drops at system design flow rates. This will result in selecting valves with a smaller envelope, but superior internal design and flow characteristics and lower valve and installation costs.

Versatility:Here are a few examples of the versatility of the Elwood Valve, illustrating multi-purpose valves. As many as nine (9) positions are available in one valve, though normally, only 4 to 5 positions are used. This flexibility eliminates the need for additional valving and manifold space. Any existing standard 3-position Elwood Valve can beconverted to provide multi-position valves. This offers considerable versatility in the field, as design requirements change, without requiring manifold or piping changes. Basic valves are interchangeable, therefore spares are minimized. In addition to the illustrated functions, several others are available; contact Elwood.

Features:This example demonstrates how circuit design, manifolding and piping are simplified. This is achieved by eliminating the need for piped-in or manifolded speed and flow control valves. The Elwood Valves have integral externally adjustable flow control screws.

Heavy-Duty Durable Design UsingCorrosion-Resistant Materials:Seals are self-compensating. The same piston rings are used throughout. Spool is hydraulic-balanced, assuring uniform wear and eliminates concentricity problems. Designed with no-lap fitted parts.

Versatile:Changing the main valve function is accomplished by changing pilot spool and plugs. Multiple positions of the main valve are achieved by mounting an additional pilot valve. For additional pilot valve information see Bulletin E82. Recommended air supply: 60 psi (4 bar) minimum;120 psi (8 bar) maximum inrush current for 110/120 Volt 50/60 Hzand 220/240 Volt 50/60 Hz is 87 VA, holding 30 VA.

Option 22 - Check and Choke Plate arrangement allows the customer to adjust the shifting time of the main valve by controlling pilot flow.

Option 31 - Provides visual external indication of the poppet position by means of viewing the pin position. This can aid in troubleshooting.

Option 33A, 4-Way Valves, provides for piloting from the normal pressure source and/or the A cylinder port.

Option 33B, 4-Way Valves, provides for piloting from the normal pressure source and/or the B cylinder port.

Option 33C, 3-Way Valves, provides for piloting from the normal pressure port and/or the cylinder port.

Option 33D, 4-Way Valves, provides for piloting fromthe normal pressure port and/or an external pilot supply.

Versatility:Here are a few examples of the versatility of the Elwood Valve, illustrating multi-purpose valves. As many as nine (9) positions are available in one valve, though normally, only 4 to 5 positions are used. This flexibility eliminates the need for additional valving and manifold space. Any existing standard 3-position Elwood Valve can beconverted to provide multi-position valves. This offers considerable versatility in the field, as design requirements change, without requiring manifold or piping changes. Basic valves are interchangeable, therefore spares are minimized. In addition to the illustrated functions, several others are available; contact Elwood.

Features:This example demonstrates how circuit design, manifolding and piping are simplified. This is achieved by eliminating the need for piped-in or manifolded speed and flow control valves. The Elwood Valves have integral externally adjustable flow control screws.

Heavy-Duty Durable Design UsingCorrosion-Resistant Materials:Seals are self-compensating. The same piston rings are used throughout. Spool is hydraulic-balanced, assuring uniform wear and eliminates concentricity problems. Designed with no-lap fitted parts.

Versatile:Changing the main valve function is accomplished by changing pilot spool and plugs. Multiple positions of the main valve are achieved by mounting an additional pilot valve. For additional pilot valve information see Bulletin E82. Recommended air supply: 60 psi (4 bar) minimum;120 psi (8 bar) maximum inrush current for 110/120 Volt 50/60 Hzand 220/240 Volt 50/60 Hz is 87 VA, holding 30 VA.

Option 22 - Check and Choke Plate arrangement allows the customer to adjust the shifting time of the main valve by controlling pilot flow.

Option 31 - Provides visual external indication of the poppet position by means of viewing the pin position. This can aid in troubleshooting.

Option 33A, 4-Way Valves, provides for piloting from the normal pressure source and/or the A cylinder port.

Option 33B, 4-Way Valves, provides for piloting from the normal pressure source and/or the B cylinder port.

Option 33C, 3-Way Valves, provides for piloting from the normal pressure port and/or the cylinder port.

Option 33D, 4-Way Valves, provides for piloting fromthe normal pressure port and/or an external pilot supply.

Page 6: DIRECTIONAL CONTROL VALVES 2-, 3- AND 4-WAY DIN POPPET …

Directional Control ValveValve Sizing

Valve sizing and selection requires consideration in two (2) areas:

1) PIPE VELOCITY & PRESSURE DROP Allowable maximum pipe velocity is based on various system considerations and fluid velocity and resultant pressure drop. Generally, the following flow rates are acceptable parameters for most piping systems:

- for short-to-medium length runs, 26 feet per second (8 meters per second), and a maximum of 30 feet per second (9 meters per second). - for long piping runs, 20 feet per second (6.5 meters per second).

These parameters consider pressure drop. However, to do a complete engineering analysis, one would need to calculate the length of actual pipe runs, factoring in the number of elbows, valves, etc., to determine the system pressure drop. In this case, Cranes Referenceor other reference can be used.

2) PRESSURE DROP THROUGH THE VALVE For correct valve sizing, it is necessary to determine pressure drop through the valve. Due to the fact that not all manufacturers clearly state their valve flow characteristics, it may not seem easy to determine the pressure drop. But, it is simple when the Cv is given. The most effective method for comparing alternative valves is by the Cv factors that valve manufacturers provide for each individual valve. This enables engineers to calculate and compare pressure drops at system design flow rates. This will result in selecting valves with a smaller envelope, but superior internal design and flow characteristics and lower valve and installation costs.

The Elwood line of DIN Poppet Directional Valves is a modern controls concept in water hydraulics - a line of 2-, 3- and 4-way control valves

incorporating the following features:

Zero Leakage - Positive, drop tight sealing is achieved by poppet type plunger assemblies with resilient seating discs, which close against heat treated stainless steel mitered seats.

Extended Poppet Seal Life - The dynamic seals nevercross ports during operation, therefore, cannot extrude intoports. These seals are wear compensating.

Minimal Valve Space Requirements - Compact subplate mounted design reduces space requirements by as much as 50%.

Easy Valve Maintenance - All normal maintenance can be performed from the top side of the valve without removing the valve from the system. The internals are designed eliminatingall "press" fitted as well as "selectively" locked parts orassemblies. Cavities conform to international DIN standardsand are sleeved to facilitate seal and parts replacement.

Directional Control Function Flexibility - Main controlvalve function can be changed by removing the top plate and relocating the plugs in the pilot fluid passageways.

Less Inventory Required - Because such parts aspoppets, seals, etc., are interchangeable between 2-, 3- and 4-way valves, spare parts inventory requirements are minimized. Exchanging the poppet assembly replaces all dynamic seals.

Built in Flow Controls - Totally independent "meter-in"and/or "meter-out" flow control from either port is accomplishedby simply limiting the poppet stroke by use of the externally accessible stainless steel flow control screw.

Maximum Efficiency of Fluid Flow - The design of the passage-ways through Elwood Directional Control Valves,results in outstanding valve efficiency and minimum pressure drops, allowing smaller Elwood valve size selection for most applications. Thus, it is smaller in comparison to competitive valves and requires less manifold space.

Pilot Designed to Suit Application - For heavy duty milltype applications, our standard air actuated packed spool pilot valve (Bulletin E82) is furnished. This valve requires no secondary operating media.

Six Poppet Models Available - Designed for dual speed applications. SIMPLIFIED SECTION
