API Cast Steel Gate Valve

API Cast Steel Gate Valve

API cast steel gate valve is a kind of gate valve which is mainly made of cast steel according to the valve standards and specifications of API-American Petroleum Institute. API cast steel gate valve is a double disc gate valve with the Outside Screw & Yoke, Bolted Bonnet Design. The body materials of API cast steel gate valve are cast steel, alloy steel, stainless steel and trim material. As for the design standards of API cast steel gate valve, there are API600 , BS1414 , API603 , ASME B 16.34. API cast steel gate valves’ size ranges are ANIS Class 150, 300 and 600.

As one kind of gate valves, AIP cast steel gate valve has the features of gate valves. Therefore, it is also most commonly used as shutoff valves in industry today. AIP cast steel gate valve is used where minimum pressure drop and bi-directional on-off service is required, is manufactured to provide maximum service life and dependability and is not designed for throttling service. Prolonged use in the partially open position is likely to damage seating surfaces. AIP cast steel gate valves are ideal for neutral media such as water, drinking water, seawater, air and so on. AIP cast steel gate valves are available with different wedge configurations (solid, flexible and split) to meet specific service conditions. Normally gate valves are provided with flexible wedges unless otherwise asked for. Valves with class 150lb & 300lb ratings in sizes up to 300m are normally handwheel operated. Sizes 350mm and above in class 150lb & 300lb ratings are gear operated. Class 600lb valves are handwheel operated in sizes up to 200mm and gear operated from 250mm and above. AIP cast steel gate valves can also be fitted with a range of electric actuators
