RPB - FLANGED PISTON VALVE

Features


A stainless steel piston enclosed by two resilient valve ring forms the sealing system. The sealing area is the surface of the piston. The upper valve ring ensures tightness against the atmosphere while the lower valve ring provides sealing across to ports.

Advantages & cautions


Assets : 
  • Asbestos free
  • Reliable, leak-tight shut off in line and to the atmosphere
  • Unique robust construction principle
  • Insensitive to impurity
  • Long service lige and optimized life cycle cost
  • Excellent regulation of flow
  • Maintenance free
  • Valve remains in line if replacement of seat rings and internal parts are necessary
  • Designed for automation using electro-mechanic or pneumatic actuator

Design Pressure : 16 bar - 25 bar - 40 bar

RPF - SCREW PISTON VALVE

Features


Piston valves have two important components : fine ground cylindrical piston made of stainless steel and elastic valve rings. Suitable ring materials are used for almost all kinds of fluids. Elastic upper lower rings compress the piston with the required tightness. Thrust is provided by tightening the bonnet nuts. It is transmitted from upper ring to lower ring via lantern bushing. Axial thrust is converted to radial pressure by compressing the elastic rings. The compressed rings enable an outstanding leaktightness. the lower ring is leakproof across the ports, the upper ring is leakproof to atmosphere. At fully open or fully closed position, since there is no contact between the cylindrical piston surface and the fluid; abrasion does not take place
