Right Angle Relief Valves

Pneu-Hydro right angle relief valves are pressure balanced internally and pressure referenced to atmosphere. This yields insensitivity to downstream pressure and permits the valve to be used as a back-pressure regulator. The valve seals against a soft seat and has a metal stop that bears the spring load, prolongs seal life, and prevents sticking.

These valves remain bubble-tight up to cracking pressure and reseal bubble-tight at less than 10% drop from cracking pressure (significantly less in the higher pressure ranges). The external setting adjustment is particularly useful in applications where changes are required. The design provides full flow at a very small rise above cracking pressure.

Features include a wide series of available pressure ranges, smooth, chatter-free performance, reliable and repeatable cracking and reseating pressures, along with 316 stainless steel construction. Seal material selections are available for compatibility with virtually any fluid chemistry. Standard seal materials are Buna-N and Viton.
