Relief Valves

Relief Valves (Factory Set)

Relief valves are offered in pressure ranges: 1,500 through 60,000 psi.

Standard materials include 316 stainless steel bodies and removable seat glands with 17-4PH stainless steel removable seats and pistons. Standard O-ring material on the piston is Viton Valves may be used up to 350 F.

Inlet connections are for 9/16" O.D. tubing (HF9) with adapters for other sizes available. Outlet connections are 1/2" NPT. These valves are not recommended for use below 1,500 psi, and are not readily adjustable in the field without proper test equipment. Pressure settings are made at the factory and valves are tagged accordingly.

To order, simply specify catalog number and set pressure. See table below.

Relief Valves (Field Adjustable)

Relief valves are offered in pressure ranges: 1,000 through 20,000 psi.

Standard materials include 316 stainless steel bodies and seat glands. Standard O-ring material is EPDM, with teflon packing and nylon seats.

Inlet connections 1/4" NPT-HIP-10RV; HF4-HIP-20RV.
Outlet connections are 1/4" NPT.
These valves are not recommended for use below 1,000 psi, and are readily adjustable in the field.

To order, simply specify catalog number. Example: HIP-10RV
