PM/ (D) S Pressure or Vacuum Relief Valve

Brand: PROTEGO
The PM/(D)S type pilot-controlled Protego diaphragm valve is a highly developed valve for pressure and vacuum relief.

It is primarily used as a safety device for outbreathing in tanks, containers, and process engineering equipment and it also offers reliable protection from vacuum and overpressure.

It prevents the intake of air and unacceptable product vapor loss up to the set point. The valve can also be used as inbreathing valve.

The main valve is directly controlled when it is exposed to a vacuum; e.g., it functions as a weight-loaded diaphragm valve.

This valve is highly suitable under atmospheric conditions and for use in cryogenic service.
Features
  • High degree of safety due to double pilot
  • Controlled by corrosion-resistant, low-temperature-resistant permanent magnet
  • The tank medium does not continuously flow through the pilot valve
  • Pop-open characteristic from a minimum pressure rise to full lift
  • Extreme tightness and hence least possible product losses and reduced environmental pollution
  • Set pressure is close to full lift pressure, which results in high level of design freedom and product savings
  • High flow capacity
  • The control diaphragm of the main valve is shielded from low temperatures-high-level durability
  • Can be used in areas subject to an explosion hazard
  • Designed for use at low temperatures
  • Self draining
