Pneumatic three-way flange ball valve

         Pressure-control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit. Types include relief, reducing, sequence, counterbalance, and unloading. All of these are normally closed valves, except for reducing valves, which are normally open. For most of these valves, a restriction is necessary to produce the required pressure control. One exception is the externally piloted unloading valve, which depends on an external signal for its actuation.

Pneumatic Actuator
 

1,Indicator

     Position indicator with NAMUR is convenient for mounting accessories such as Limit Switch box, positioner and so on.


2,Pinion

     The pinion is high-precision and integrative,made form nickelled-alloy steel, full conform to the latest standards of ISO5211,DIN3337,NAMUR. The dimensions can be customized and the stainless steel is available.


3,Actuator Body

     According to the different requirements, the extruded aluminum alloy ASTM6005
Body can be treated with hard anodized, powder  polyester  painted ( different
colours is available such as blue, orange, yellow etc.),PTFE or Nickel plated.


4,End caps

     Die-casting aluminum powder polyester painted  in  different  colours,  PTFE  or Nickel plated.


5,Pistons


     The twin rack pistons are made form Die-casting   aluminum   treated   with   Hard anodized or made form Cast steel  with galvanization. Symmetric mounting position, long cycle life and fast operation, reversing rotation by simply inverting the pistons.


6,Travel adjustment

    The tow independent external travel stop adjustment bolts can adjust±5°at both open and close directions easily and precisely.


7,High performance springs

    Preloaded coating springs are made form the high quality material for resistant to corrosion and longer service life, which can be denounced safelyand conveniently to satisfy different requirements of torque by changing quantity of springs.


8,Bearings & Guides

    Made form low friction, long-life compound material, to avoid the direct contact between metals. The maintenance and replacement are easy and convenient.


9,O-rings

    NBR rubber O-rings provide trouble-free operation at standard temperature ranges.For high and low temperature applications Viton or Silicone.
