Features

  • These soft seat safety valves have an elastomer (Viton / silicon) seal that ensures zero-leakage and can resist high temperatures up to 400 degrees F and pressures ranging between 25 to 300 psig.
  • They open at a predetermined set pressure and close when the system pressure has returned to a safe level.
  • They feature a spring-loaded mechanism that exerts a force on the sensing element and acts to close the valve.

Standards and Approvals

  • ASME
  • CSA

Frequently Asked Questions

What should be the mounting orientation to install a pressure safety valve?

The SRV valves should be installed vertically to ensure that the valve body is self-draining and the correct seat tightness and set pressure are achieved.

How to maintain the valve?

Take a visual inspection and check for clogged drains & drainage pipes, dirt buildup around the seat and broken, damaged or missing parts and seals.

What is the purpose of a drain hole in the valve body?

The drain hole prevents condensate from accumulating in the valve body which could freeze or corrode internal valve parts.
