Your Benefits

Increased operating pressure

Pilot-operated safety valves open from an overpressure of 1% and close from a pressure of 97% of the set pressure. This allows you to increase the operating pressure of the system.

Less media loss

Thanks to the low overpressure difference and the tightness until set pressure, the loss of media in case of an emergency is reduced compared to other designs.

Back pressure independent

Due to their design, pilot operated safety valves only react to the pressure on the inlet side and thus operate independently of the back pressure.

Robust design

LESER's low-maintenance, durable design for efficient operation of your plant. The design with integrated piping makes LESER pilot operated safety valves smaller and lighter.

Offshore proven

The LESER High Alloy level concept and corrosion protection systems according to FROSIO, ISO 12944 C5M and NORSOK M-501 meet the high requirements for corrosion resistance.

Worldwide availability
