With the 3-way characterizedcontrol valve the flow through thebypass (B-AB) is designed for 70%of the nominal flow (A-AB).

A lication notes for 3-wa characterized control valves

Because it uses a ball the 3-waycharacterized control valve is onlyof limited use for conventionalsupply-temperature controlsystems. Therefore, it is advisablefor supply-temperature control

systems to be executed in theform of double mixing circuits.There are no such restrictions onmixing circuits for air preheatersand injection circuits.

The Belimo Characterized Control Valve

delivers more! Find out below why the Belimo

Control Ball Valve

is one of the most excite new developments inHVAC!

What is a characterizing disc and why do I need one?Belimos characterizing disc (patent pending) provides a simplesolution to a long-standing problem with HVAC ball valves. Alwaysattractive from a cost standpoint, ball valves were used whereaccurate control was not important. A traditional full port ball valvehas a poor flow characteristic in that it has a large flow coefficient(Kvs) in relation to its size. This means that the valve will supplythe required flow when it is only slightly open. Thereby utilizing just

a small portion of its operating range. Stable control is difficult toachieve because a slight change in valve position results in adisproportionately large change in the heating or cooling output ofthe controlled device. Energy consumption is increased, peopleare less comfortable, and life span of valves and actuators isshortened because they never come to rest. Belimo characterizedControl Valves have changed all that. They feature a special discfitted inside the inlet port. A key in the disc prevents rotation. One side of the disc isconcave and matches the surface of the ball. Flow is controlled by the opening in theball and by a V-shaped opening in the disc. This reduces the flow coefficient (Kvs). Thevalve increases flow slowly, especially when it begins to open. Therefore, equalpercentage flow characteristic is provided and the resulting heat output is linear.

Why are there multiple Kvs choices for one valvesize?Characterizing discs with different shaped openings are availableso that a number of Kvs values can be offered for each valve size.This allows you to size more valves equal to pipe size, so youspend less time and money on pipe reductions, and can easilyachieve accurate control.

Then determine which pipe diameter could be used. When pipediameter is equal to valve diameter there is no reduction in pipesize and better overall cost for an installed valve.

Why do I need a ball valve with Kvss typical of globe valve Kvss?Piping systems are still designed with globe valve flow requirements in mind. The Kvsratings of the Belimo Characterized Control Valves were based on typical globe valveKvs ratings. Therefore, you can size a project as you would if using globe valves, butcan easily select our valve. This is your assurance that the Belimo CharacterizedControl Valve will give you the performance of a typical globe valve, and more, at a more

favorable price!

Why do I need accurate valve control?Better valve control prevents hunting of the control loop in which the system isconstantly adjusting itself to maintain set point. When the operating conditions of theactuator are improved and the full operating range is used, systemlife span is increased, energy consumption is reduced, andcustomers and their tenets are satisfied.

Why two O-rings?

Two heavy duty O-rings in the stem eliminate leaks and ensurelong maintenance-free service life. Double O-ring eliminate theneed for a packing nut which in HVAC applications may requirefrequent tightening.

The inner O-ring seals against the water pressure. It is lubricatedand protected by the outer O-ring, which prevents debris fromentering the stem seal. Non-water-soluble grease between the tworings prevents sticking.

Why a flanged-type bonnet?Extremely accurate control capability comes from the mechanical advantage of direct

coupling combined with the flow efficiency of the characterizing disc. The actuatorconnects square and true to a special bonnet flange. This eliminates any lateral stemmovement that would wear stem components and cause leaks. Four differentactuator/pipe orientations can be achieved.

What is TEFZELTM

?TEFZEL

TM, is a tough, enhanced Teflon

material used in industrial

applications such as bearings, valve linings, tubing and waterpumps. TEFZEL

TM offers broad thermal capability, corrosion

resistance, and low coefficient of friction and water absorption. Thecharacterizing disc is made of this unique material, which allows theball to move freely against the disc and maintains fluid motion.

What about cavitations?Because of improved operating characteristics, the Belimo Characterized Control Valveis far less prone to cavitations than the standard ball valve. Cavitations occur whenvapor bubbles form and implode in a liquid due to an increase then decrease in pressureas liquid flows through a restriction. The imploding vapor bubbles erode the surroundingmaterial and cause an intense noise. Like globe valves, no cavitations should occur ifthe valve is sized properly.

What is that small hole near the top of the flanged bonnet?This vent hole prevents any condensation built-up in cooling applications from enteringthe linkage and actuator-one of the many small steps weve taken to ensure completereliability.

The Belimo Characterized Control Valve is an improvement overtraditional ball valves, but is it better than globe valves?Yes! The Rangeability factor defines a valves capability to control small flows. Thehigher the number, the better. On typical small globe valves (15mm) the rangeability is5:1, and on a large valve (50mm) it is 75:1. The Belimo control valve has a rangeabilityof 500:1 for greatly improved control, especially at low loads.

OK, Im convinced the engineering is good, but does it work?Absolutely. The Belimo Characterized Control Valve design has been extensively testedwith respect to pressure, temperature, leakage and life cycle.

Does this control valve have the same actuator Im used to fromBelimo?You bet, Enjoy the same benefits youve always had with Belimo!

4, CCV, 3 GV8/22/028/28/02

Test Objective: To determine the effects of calcium carbonate scale buildup on the durability of BelimoCCV and Competitor Globe Valves.

Conclusion: After 100,000 cycles, the Belimo CCV appears to be unaffected by the presence ofscale. The competitor valves can no longer close off.

Action: None at this time. Test was originally scheduled to run past 100,000 cycles, but that iscancelled at this time due to the nature of the globe valve failure.

Summary ofResults:

Belimo break away torques collected before and after testing for Belimo CCV (globe

valves not tested for torque since Belimo does not have a linear torque tester):

Maximum allowable torque is 35 inch pounds. The presence of scale did not increase

torques enough to cause failure.

After 101,611 cycles, 2 CCV and 1 globe valve were removed from a bath containingwater with an LSI >0.05 at an ambient temperature of 150

OF. Belimo valves 1 and 2

achieved a 100 psi close off against running water. No leakage was seen through thestem area. The globe valve 1 achieved a 30 psi close off against running water. Noleakage was seen through the stem area.

After 105,048 cycles, 2 CCV and 2 globe valves were removed from a life test fixturecontaining room temperature water with an LSI greater than 0.05. The fixture is designedto allow 30 psi of head pressure on the valves to simulate running water. This is thesame test setup as the previous life test done with water having an LSI of 0. BelimoCCVs 3 and 4 both achieved a close off of 100 psi against running water. No leakage

was seen through the stem. Globe valves 3 and 4 would not close off, even against 10psi. (See figure 1) The valves were assembled to competitor actuators set for fail closed.No leakage was seen at the stem area.

Figures 3 and 4.CCV Balls after life test. Note scratches on ball. Presence of scratches did notaffect close off or operation of the valve

The valve stem was then removed and inspected for wear. Both stem O-rings were ingood condition and grease was still present. (See figure 5)

Figure 5.CCV Stem after life test. Note that O-rings still have shape and the presence ofgrease on the assembly.

All other components of the valve, including the Teflon seats and the O-rings behindthem, were in good condition as well.

The globe valves were then disassembled to determine the cause of the close off failure.The globe valve stems were removed and a patch of heavy scratching and a patch ofwear were found. The wear and the scratching were found exactly opposite of each otheron the valve. (See figures 6 and 7.)


23/25



Figures 6 and 7.Wear patterns on competitor Globe Valves

Due to the presence of the wear patch, asymmetric loading of the valve stem wasassumed to be the cause of valve failure. The competitor pneumatic actuator was

inspected to see if it was possible for the installation of the actuator to create the sideloading. It was found that the actuator was self-centering and could not have caused anyside loads. (See figure 8)


24/25



Figure 8.Bottom view of pneumatic actuator. The brass nut fastens to the valve stem. Thespring base is then self-centering underneath the diaphragm.

The inside of the valve was then inspected and excessive wear was seen on the valve

seats and packing on the upstream side of the valve only. It is assumed that the scaleand debris of the valve collected on the upstream side of the valve stem, and that over aperiod of time, was able to amass enough to cause a side loading. This same life testwas conducted using the same actuators without the presence of scale. In that test, allvalves functioned properly after 100,000 cycles.

Test Methods:

2 Belimo CCVs and 2 GVs will be piped into standard life test configuration and thewater will be placed under pressure. Water to have an LSI value greater than 0.05 andbe at room temperature.

2 Belimo CCVs and 1 GV are to be placed in a bath of water with an LSI greater than0.05. This bath to be heated to 140F. Failure of pneumatic actuator during this test shall

NOT be considered failure of the unit. This test shall run for 100,000 cycles only.

All valves to be cycled using pneumatic actuation with a period of 2 seconds, ON; 2seconds OFF.

All valves to be disassembled for inspection after 100,000 cycles.
