Spring type return safety valve

I. Product display and introduction

The Justking 3"RR spring-loaded reposition relief valve protects the mud pump and mud manifold to ensure a safer operation during drilling.Replace shear-type safety valves to reduce mud pump downtime and avoid downhole accidents during pump downtime.The Justking 3"RR Spring Reset Relief Valve is available with LPT, FMC WECO, or 3-1/8" flanges and can be set flexibly with pressure ratings from 400 to 5,000 psi (2.8 to 35 MPa).

Justking 3" type RR spring type reposition safety valve adopts integral piston structure, simple appearance, beautiful appearance, easy to replace wearing parts;Sensitive opening, pressure relief can be achieved without stopping the pump manual reset;The pressure fluid adopts built-in double protection to avoid damage to other equipment and personnel caused by high pressure fluid overflow when sealing failure.
