Cast Steel Rising Stem Rigid Wedge Gate Valve For Water, Steam And Oil Use
Product Introduction:
Gate Valve is a particular type of valve product that regulates fluid flow in pipeline by opening or shutting a gate or wedge that moves vertically to let or limit fluid flow. Idealistically, it shouldn’t be utilized as a regulating valve or control valve. The gate travels perpendicular to the service flow, hence the name. The most typical and straightforward form of valves are gate valves.
Gate valve is always used to open and close pipelines, not used to throttle flow, and stainless steel gate valve for nitric acid type application and cast steel gate valve normally for water, steam and oil pipeline application,
Gate valves are frequently opened and closed by spinning a handwheel or utilizing a bevel gear actuator, pneumatic actuator or a motorized actuator to rotate a threaded stem.
