Pressure Relief Valves Our Weco pressure relief valves are direct acting, self reseating valve designed for over pressure protection, pumps, pressure vessels and pressure pumping applications. We offer a standard Pressure Relief Valve and an Electronic Pressure Relief Valve. Standard Pressure Relief Valve 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. To determine which pressure relieve valve meets your technical specifications and applications. Introduction and Product Explanation The FMC 2” Figure 1502 1, 000 to 15, 000 psi pressure relief valve is a direct acting, self reseating valve. The relieving mechanism is a spring loaded ball and seat arrangement and will relieve fluid at pressures up to 15, 000 psi. An adjustment screw at the top of the valve allows the relieving pressure to be adjusted form 1, 000 to 5, 000 psi or 5, 000 to 15, 000 psi based on the spring configuration and number of springs. The valve can be preset at the factory or adjusted in the field. The integral end connections for the valve are FMC WECO Figure 1502, wing union connections. Recommended Operating Practices Installation and Maintenance Requirements The FMC relief valve should be mounted in the vertical position on a branch of the high pressure line. Mounting the valve vertically will reduce the likelihood of any contaminants settling inside the valve, thus, reducing the chance that the valve will remain open and leak after it has relieved. To assure that the valve will continuously reseal after relieving, one should only relieve liquids that do not contain large suspended particles. Fluids that contain large particles, such as proppants, should be isolated from the valve using an isolator valve between the pressure line and the relief valve. When installing a relief valve, the following standard practices should be used: 1. Lubricate the connector threads prior to initial make-up. 2. Inspect the seal ring ( item # 11) prior to each installation. 3. Assure that the end connections are made up fully andtight before pressurization. 4. Assure that all pressure is bled from the line beforeloosening any end connections. 5. Insure the valve or the attached discharge plumbingis positioned with the discharge pointing away from personnel and equipment. 6. Insure that there are no restrictions in the discharge piping. 7. Make sure the pressure setting is correct on the relief valve for the application. Advantage: Recommended service Over pressure protection for pumps, treating lines, and pressure vessels. Note: The FMC Technologies 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. Easily Adjusted Adjustment screw allows the relief pressure to be easily adjusted in the field. ACME Thread Body Cap Full ACME thread engagement between body and body cap ensures 3: 1, burst pressure: cold working pressure ratio. Belleville Washers To ensure reliable closure, Belleville washers act as a spring to resist fluid pressure. Various spring stack configurations are available for different relief pressure ranges. Field Repairable If ball, seat, or seals need replacing, easy-to-use field repair kits are available. Relief Mechanism The spring, ball, and seat arrangement provide a direct acting, self reseating valve. No manual intervention is required to reseat the valve after pressure stabilization.
