PVC-U pressure retaining valve


Pressure retaining valves are used where a constant back pressure is required for operating process systems. When installed as a bypass, it can also be used as a relief valve for reducing pressure peaks. Our model (DN 10-50) has an almost zero-static lower body that makes it particularly suitable for use in very high-purity water applications. The variety of available materials covers a wide range of applications.

  • All parts that come into contact with the medium are made of highly-resistant plastics
  • The control diaphragm separates the actuating drive from the flow section
  • The operating pressure is adjusted with an adjustment screw and is secured with a lock nut. The setting can also be lead sealed if required
  • The shape of the housing that assists flow results in good flow values
  • No auxiliary energy is required in order to operate the valve
  • The valve is largely maintenance-free and can be installed in any position
