High-Pressure Soft Seat Relief Valves for Gas Applications



High Pressure Equipment Company (HiP) introduces a new soft seat relief valve designed to protect liquid and gas tubing systems from over-pressure damage and failure. These new relief valves are available in pressure ranges from 1,500 through 25,000 psi for 9/16" O.D. tubing with adapters for other sizes available. Outlet connections are 1/2" NPT. The soft seat valve design provides a bubble-tight seal ideal for venting gas and can be reseated.

HiP relief valves are factory set to the designated pressure and tagged accordingly. They feature 316 stainless steel bodies and removable seat glands with 17-4PH stem and seal ring for standard applications. Nitronic 50 stem and seal rings are required for hydrogen service. The soft seat material is Peek. These valves have orifice sizes of 3/8" and 1/8" and may be used up to 400°F with standard Viton O-ring or 450°F with a Kalrez O-ring option.

All HiP relief valves are now available with CE marking. These products will be proudly marked with the CE symbol, signifying they comply with the stringent requirements of the Pressure Equipment Directive (PED).
