Safety Valve
A type of pressure relief valve with a 'pop-action' (snap-open) mechanism that fully opens when set pressure is reached and remains open until pressure drops below the reseat pressure. Used on steam boilers (ASME Section I) and pressure vessels (ASME Section VIII). Sized to API 520/526.

What is a Safety Valve used for?
Safety Valves are used in industrial piping systems for on-off isolation, flow control, or backflow prevention depending on the valve type. They are selected based on the process fluid, operating pressure and temperature, required shutoff class, and pipeline size. Vajra Industrial Solutions supplies Safety Valves certified to API 6D, ASME B16.34, and other applicable standards.
How do I select the right Safety Valve for my application?
Selecting the correct Safety Valve requires specifying: (1) nominal pipe size (NPS/DN), (2) pressure class per ASME B16.34, (3) body and trim material based on fluid compatibility and temperature, (4) end connections (flanged RF/RTJ, butt-weld, socket-weld, or threaded), (5) required certifications (API 6D, ISO 9001, fire-safe API 607).
