摘要： A surge relief angle valve (SRA) is disclosed. The surge relief angle valve is held normally-closed by one or more compression spring(s). In certain embodiments the surge relief angle valve includes a body containing a disc and disc seat; a piston and shaft, the piston and shaft in communication with the disc and disc seat; and a spring providing a force against the piston; wherein the spring is enclosed within a housing and wherein the surge relief valve has a closed self-contained hydraulic system containing the piston and shaft, and providing a dampening force against the spring force.

摘要： The present invention is directed to improved valves having removable interior wear rings and valves containing the removable wear rings. In an example, the wear ring comprises a high-hardness metal ring, the high hardness metal ring having an exterior surface configured to engage the body of gate valve. A polymeric overlay covers at least a portion of the exterior surface of the metal ring, the polymeric overlay forming the final dimensional shape of the wear ring.

摘要： Embodiments include a check valve that comprises a valve body defining an inlet port and an outlet port; a disc disposed within the valve body, wherein the disc is coupled to a pivot shaft and the pivot shaft is coupled to the valve body; a lever arm coupled to the disc, wherein when the disc rotates the lever arm rotates; an actuator shaft couple to a motor, and a first interference element coupled to the actuator shaft, wherein the lever arm contacts the first interference element when the disc is in a maximum open position; wherein when the motor rotates the actuator shaft moves longitudinally along its axis to move the first interference element thereby changing the maximum open position. Other embodiments are also included herein.

摘要： The present disclosure is directed to a combination air valve that uses buoyancy to lift seals into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve. The combination air valve includes a low flow vent configured with a pressure equalizing configuration allowing for reduced extrusion forces along the low flow vent, allowing vertical movement of a float shaft at high valve gas pressures with reduced forces.

摘要： The present application is directed, in part, to a device for delivering epoxy material behind the seat of a butterfly valve, the device comprising: a shaft having a first end, a second end, and an internal lumen between the first and second end. The shaft is configured for insertion into an opening in a valve body such that epoxy injected into the first end of the shaft travels along the internal lumen of the shaft to the seat, thereby applying pressure to the seat to press it toward the valve disc.
