Goodwin Check Valves are available in 5 basic body styles: Wafer, Flanged, Solid Lug, Buttweld end, Hub end, and in an extensive range of sizes, pressure classes, and materials. Its principal features are those of it being Retainerless as standard, i.e. nobody plugs, and its patented “slim” plate design giving improved flow efficiencies and superior metal-to-metal seating shut-off. The Goodwin Check Valve embodies other performance-enhancing features such as Plate Shock Bumpers, Independent Plate Closing Action, and heel lift (Seat Life).
Forged steel valves are used in Oil Refining and other industrial applications where forged steel material is required. Higher pressures and temperatures are usually involved and the line size is generally under the size of “2”. In other conditions, forged steel valves might be a good choice for better performance, such as system requirements for socket-weld piping and compatibility of media. Forged check valves, forged gate valves, forged globe valves are a few of the different types, and depending on what the media is, depends on which one is used.
Global Valve and Controls trunnion design ball valves incorporate the use of upper and lower supports (GVC trunnion plate system) to retain the ball under pressure. Global Valve and Controls API 6D trunnion ball valves have a secondary sealant injection system for stem seals and seats in the event of providing a temporary seal to an otherwise damaged area. The Global Valve and Controls trunnion ball valve design using the upper and lower trunnion plate system essentially doubles the safety and reliability of a standard trunnion ball valve.
