Wedge Gate Valve Cast Steel - S/Z40H Z541 41H - Farpro Valve These wedge gate valves cast steel S/Z40H Z541 Z41 are suitable for fully open and fully closed pipelines, not for throttling. Wedge gate valves made of cast steel are commonly used in high-pressure and high-temperature applications, particularly in the oil and gas industry. The cast steel material provides the necessary strength and durability for these demanding applications. The wedge gate valve design features a gate or wedge-shaped disc that slides between two parallel seats to control the flow of fluids. When the valve is fully open, the disc is completely removed from the flow path, minimizing pressure drop and turbulence.
