Designed with tamper-proof qualities, this vent to atmosphere high-pressure relief valve is suitable for liquid or gas-based applications. With an encapsulated o-ring seal and narrow-band interchangeable springs, this relief valve eliminates seal extrusion, cold flow, and minimizes system pressure rise.

With seat and poppet geometry combined with optimized spring ranges, this industrial relief valve provides high flow rates with minimum pressure accumulation. Relief pressure can be discharged to the atmosphere or a downstream connection.

Compacte, très précise et à action directe, cette vanne de décharge est préréglée en usine selon les spécifications de pression et/ou de débit souhaitées. Avec une bague d'étanchéité quadruple, cette vanne offre une précision extrême ainsi qu'une répétabilité avec une bande de réinstallable étroite.

Compact, highly accurate, and direct-acting, this vent relief valve is factory preset to desired crack pressure and/or flow specifications. With a quad ring seal, this valve provides for extreme accuracy as well as repeatability with a narrow reseal band.
