Application-based Solutions: Increased efficiency and productivity in your plant with LESER Pilot Operated Safety Valves
We efficiently secure your plant with an operating pressure of up to 426 barg / 6170 psig with our Pilot Operated Safety Valves (POSV).
Construction of a POSV
The POSV consists of a main and a pilot valve. The pilot valve has two designs: The pop action-design ensures a rapid opening of the main valve. This version is important for applications where the discharge capacity needs to be reached quickly e.g. for gas applications. The modulate action-design has a gradual opening. The aim is, to minimize the media loss. The Pilot Valves are robust and not sensitive to vibrations, which guarantees a safe working even if there are vibrations and oscillations in the system.
Spacialties about the POSV
A POSV has a higher tightness especially near the set pressure, resulting in possible operating pressures of up to 97% of the set pressure. Besides, POSV are applicable for high back-pressures of up 70% of the set pressure. Above that, the POSV has a compact construction and a lower weight.
Possible application areas are:
- compressors in gas main systems
- blow-off pipes in the oil and gas industry
- feed pipes in the oil and gas industry
- pumps in all industries
- Off-shore (platform, FPSO)
