Line of relief valves protects a system from over-pressure damage and failure of gas or liquid service. The factory set relief valves offer pressure ranges from 1,500 through 60,000 psi and 17-4PH stainless steel removable seats and pistons. Viton O-ring is standard on the piston and the valves may be used up to 350°F. These factory-set relief valves are not recommended for use below 1,500 psi and are not readily adjustable in the field without proper test equipment.
