4 Gate Valves. 5 - 43 Nuclear. 44 Sour Service. Gate valves are designed tooperate in a fully open or fully closed position. When open, the media will flow with minimal turbulence and pressure drop through the valve.Vogt gate valves are availablewith a variety of bonnet types, body and trim materials and stem packings in addition to a broad range of pressure classes, and end connections including extended bodies.The rugged construction ofFORGED gate valves provide an extended life of safe operation.

Globe and Angle valves are suitablefor throttling as well as shut-off. They are customarily installed so that the media pressure and preferred flow direction is under the disc (as illustrated). Flow above the disc is also acceptable.The Vogt Globe and Angle valve linesprovide a variety of design variations to fulfill your requirements.
Flow characteristics can be determined from the Cv Factors listed on pages 122 and 123.Bellowseal globe valves are suitablefor applications requiring total containment of the flowing media frequently necessary to protect the environment and to eliminate the loss. Vogt check valves are forged fromfine grain steel and are available with threaded, socket weld or flanged ends. Most bonnet designs, including bolted, seal weld, union, and bonnetless type check valves are manufactured to meet a wide variety of service applications.Piston, ball, swing and springcontrolled check valve designs for horizontal or vertical (upward) flow applications for the most often specified pressure classes are available.
Aspring can be added to piston check valves not currently equipped with that option if specified on the order.Vogt֒s YӔ pattern check valvescomplement our YӔ. All FLOWSERVE catalogues and technical brochures.
