The stop block could strictly guarantee stem stroke, protect-

ing bellows from out-of-stroke deformation, and ensures the

service life of bellows .

Back seat will make sure no leakage from the stem when

valve open.

The design of guide gasket could avoids the wall-hitting is-sue of bellows under an unstable situation,also could prevent the friction between bellows and stem. Also,the gasket could strengthen the inflexibility of stem, avoiding the fluttering phenomenon when medium passing by and improving the service life of bellows.

We apply flexible graphite as the secondary sealing device so

to prevent abnormal medium leakage.

Sufficient number of bellows could effectively guarantee ser-

vice life of the valve.

The enlarged medium passing area ensures the flow capaci-

ty of valve, avoids high speed passing medium on the sealing

face, in this case erosion, cavity and flash can be restrained

effectively. With a guide disc, the valve can be installed ver-

tically, and regulating function can be designed conveniently.

Didtek DIN Globe Valves are manufactured to the latest edition of EN 13709 and tested to EN12266-1.Application & Function:Didtek Din Globe Valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop. The globe valve is an excellent valve to use for on-off service, but is high-ly suited for frequent cycling and control of fluids anywhere in amount or volume between the open and closed positions.Didtek Din Globe Valve must be installed in the proper relation to the media flow as indicated by the flow direction arrow marked on the valve body. This valve is considered uni-directional and must be installed with the pressure side or inlet under the seat.Accessories:Gear operators, actuators, locking devices, chain wheels and So

Didtek DIN Angle Globe Valves are manufactured to the latest edi-tion of EN 13709 and tested to EN12266-1.Application & Function:Didtek Din Angle Globe Valve with ports at an angle are called angle globe valves. The two ports may be oriented straight across from each other on the body, or oriented at an angle such as a 90°angle. Also It is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop. The globe valve is an excellent valve to use for on-off service, but is highly suited for frequent cy-cling and control of fluids anywhere in amount or volume between the open and closed positions.Didtek Din Angle Globe Valve must be installed in the proper re-lation to the media flow as indicated by the flow direction arrow marked on the valve body.

Didtek DIN Gate Valves are manufactured to the latest edition of EN 10434 and tested to EN 12266-1.

Application & Function:

Didtek DIN Gate valves are primarily used for stop valves ful-ly opened or fully closed. They are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendic-ular to the direction of the flow. Gate valves usually have a mini-mum pressure drop when fully open, provide tight shut-off when fully closed, and remain relatively free of contamination buildup.

Accessories:

Accessories such as gear operators, actuators, bypasses, locking devices, chain wheels, extended stems and bonnets for cryogen-ic service and many others are available to meet the customer’s requirements.

Applicable Standards:- Design DIN3352- Face to face EN 558-1- End Flanges EN 1092-1- Butt welding ends EN 12627- Inspection and test EN 12266-1Size Range:- DN40~DN900Pressure Rating:- PN16~PN100Temperature Range:- -50°C~650°C

Didtek Swing Check Valves are manufactured to the latest edition of EN10739 and tested to EN 12266.Application & Function:Didtek swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the me-dia flows through the line. Back pressure in the line holds the disc in the closed position.Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indi-cated by the flow direction arrow marked on the body.Accessories:Accessories such as bypasses, locking devices, counter weight and many others are available to meet the customer’s requirements.

Design Description:



- Flange Ends

- Butt-welding Ends

- One piece body

- Unidirection

Seat and Disc has 13%Cr or Stellite Overlay to provide increased resis-tance to wear, abrasion, erosion.

Disc is secured by welded disc nut to prevent disassembly due to vi-bration and closure impact.Disc to hanger connection allows for free disc movement to avoid localized wear.

The spring also helps reduce noise, and minimize the effect of pulsating flow and “water hammer” lineshock.Applicable Standards:- Design EN13709- Face to face EN 558-1- End Flanges EN 1092-1- Butt welding ends EN 12627- Inspection and test EN 12266-1Size Range:- DN15~DN400Pressure Rating:- PN16~PN40Temperature Range:- -50°C~650°C

Didtek Lift Check Valves are manufactured to the latest edition of EN 13709 and tested to EN 12266-1.Application & Function:Didtek Lift check valve , or “non-return” valves as they are often called, are made in a variety of designs, including globe lift, piston, ball, swing, tilting disc, squib, flapper, etc. All serve the same function, which is to allow flow in one direction, while preventing flow in the other. The most common types of lift check disc is spring-loaded, fully guided by the body bore and rests on the valve seat, integral with the body. The valve is installed with the flow under the disc, such that the inlet line pressure will force the disc to “lift” off the seat and allow the line fluid to flow through the valve. Should the flow suddenly reverse itself, the disc will automatically and quickly, assisted by the weight of the disc and spring, be forced to the closed position, preventing the line fluid from returning. Some lift check valves have no spring and depend on the weight of the disc to start closure. These are called “horizontal lift check valves,” as they will only function properly when installed in

Design Description:




- One Piece Shaft

- Low torque enables the compact actuator and a long cycle life




Category DIN Triple Offset Butt Welded Butterfly Valve-DIN 3354-Specification

Didtek DIN Triple Offset Butt Welded Butterfly Valves are manu-factured to the latest editionof DIN Standard 3354 and tested to EN Standard 12266-1.Application & Function:Didtek DIN Triple Offset Butt Welded Butterfly Valve is used to prevent galling and scratches between the metal seat and the metal disc due to its unique design. The only time where the seal comes into contact with the seat is at the point of complete clo-sure. Triple offset valves are generally used in applications which require bi-directional tight shut-off in oil and gas, LNG/NPG termi-nal and tanks, chemical factories, and shipbuilding. They are also used for dirty/heavy oil to prevent extrusion.Accessories:Accessories such as gear operators, actuators, locking devices, chain wheels, extended stems and bonnets for cryogenic service

and many others are available to meet the customer’s requirements.Applicable Standards:- Butterfly valve design according to DIN3354- Face to face EN 558-1- End Flanges EN 1092-1- Buttwelding ends EN 12627- Inspection and test EN 12266-1Pressure Rating:- PN 10,16,25,40Temperature Range:- -50°C~650°CSize Range:- DN50~DN1400

Zero leakage benefited from the unique design of the disc element and meticulously machines seat to create a perfectly matched disc and seat fit, this design also ensures that the metal seat and metal laminated sealing never be in contact with each other while the valve is cycling. Contact is made between disc seal and body only as final shut off position is reached.

1st offset

The rotation axis of disc is moving back from the sealing surfaces of disc. The pur-pose of this offset is to have a continuous sealing surface on the disc.

2nd offset

The rotation axic of disc is relocated from the centerline of the body. The purpose of this offset is to lift the disc quickly off and away from the seat ring of the body.

3rd offset

The conical axis, which is extended from the sealing surface of disc, is inclined from the rotation axis of disc. The purpose of this offset is to eliminate friction, galling and wear of sealing surfaces during operations and to provide bubble tight shut-off at high and cryogenic temperatures.

About us Since year ‘1985’ our founders started the workshop for valve production, we have always been adhering to the belief that we are going to be the leader in the Chinese market on resource and development, in order to build the top standard among our competitors.

The chosen location was OuBei town, a strategic position to reach a wide range of suppliers of semi-finished products, foundries and raw materials and to be very close to Shanghai port. Since the beginning, our company policy did reward our employees who are outstanding for precision and meticulousness. Those choices get paid back immediately: from a simple workshop of 800 m2, we did expand our actual factory to over 25,000 m2 size and more than 600 employees, among whom over 20% have a university degree.

In order to fulfill our customer needs, we established a partnership with 2 valves production sites in Tianjin, a forged flange and a fitting production sites in Shijiazhuang, 5 valves and a pipe production in OuBei town then we incorporated a foundry in Li Shui.

Low cost of labor is not anymore the only advantage to produce in China as it was before, thus our second generation managers did enhance our business attitude to compete in the world market by developing quality control on our suppliers and our service, which can now compete with any European company.
