Cast Steel Gate Valve Fig.553

      Cast steel Gate Valve are manufactured to the latest edition of API Standard 600 and tested to API Standard 590.

Application & Function

      Cast steel Gate valves are primarily used for stop valves fully opened or fully closed. They are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the flow. Gate valves usually have a minimum pressure drop when fully open, provide tight shut-of when fully closed, and remain relatively free of contamination buildup.


      Accessories such as gear operators, actuators, bypasses, locking devices, chain wheels, extended stems and bonnets for cryogenic service and many others are available to meet the customers requirements.
