  • Introduction
Pressure Relief Valves is a direct acting, self reseating valve with spring washers that controls the system pressure by automatically opening and closing. It provides over pressure protection for high pressure manifolds and vessels, reciprocating plunger pumps with maximum working pressure of 15,000psi or 20,000psi. In case the system pressure exceeds a pre-set value, the valve will automatically overflow to release the pressure and it will close once the system pressure reaches the pre-set value to protect personal safety and the entire flowline.

JASON O&G offers a mechanically adjustable pressure relief valve in 2” bore sizes with a rated pressure of 15,000psi to 20,000psi . Special sealing materials ensure its servicing life.

JASON O&G has also developed pressure relief valves for H2S service in accordance with NACE MR0175 criteria with 2” bore size and 10,000psi rated pressure.

JASON O&G provides a customized design to meet each customer’s unique requirements.
