Product Description

Api Standard Flange Gate Valve:

Api standard flange Gate Valve refers to a gate valve that is designed and constructed according to the American Petroleum Institute (API) standards, specifically for use in flanged pipe connections. This gate valve adopts a wedge-shaped gate design. The sealing surface between the gate valve and the valve seat ensures sealing through the wedge force, These types of valves are commonly used in high-pressure, high-temperature, and corrosive environments where durability and reliability are essential, such as in the oil, gas, and petrochemical industries.
