WECO Pressure Relief Valves are available from SPT
Superior Pump Technologies
The Weco pressure relief valve is a direct acting, self reseating valve designed for over pressure protection, pumps, pressure vessels and pressure pumping applications.
These valves are offered in pressures up to 20,000 psi CWP in a 2 inch and 15,000 psi CWP in a 3 inch. The integral end connections for the valve are FMC Weco wing union connections.
The valve is not considered a full flow relief valve; therefore, its main function is a tattletale which indicates the set pressure has been reached. To keep the pressure from continuing to increase, other measures must be taken.
