The pop-type safety valve is designed to give high discharge capacity. Bottom guided design, good reseating characteristics and adjustable blowdown control ensures stable performance.

Pop action and modulating pilot operated safety valves with a unique full nozzle design and dimensions to API 526. Safeset valves are self-contained pilot operated safety relief valves available for both gas and liquid duties which use the system pressure to control the valve opening and closing with no other energy source required. 2017 Emerson.

Our only valves that meet ASME Code Section VIII for use with cryogenic pressure vessels. They are for use with argon, carbon dioxide, helium, hydrogen, methane, nitrogen, and oxygen. Choose from our selection of pop-safety valves in a wide range of …

The 3376/3373 pop-type bronze safety valve is of traditional design where simple features reduce both the initial outlay and maintenance costs. Good reseating characteristics and adjustable blowdown control ensures a stable performance, whilst positive shut-off is achieved by precision lapping of the seating surfaces. DN40

Well-designed POP ACTION type safety relief valves ensure safety in critical industrial applications with their fail-safe mechanism. Precision in the engineering of these valves leads to low maintenance costs.

Protect your water-heating system with these valves that meet ASME Code Section IV for hot water heaters and boilers. Also known as T & P valves, these open when water temperature reaches 210° F or at the set pressure. These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi.
