Cast Steel Wedge Gate Valve

2025-06-26

The cast steel wedge gate valve is a classic and essential flow control device widely utilized in industrial pipelines. Crafted from high-quality cast steel materials like WCB, it combines strength, durability, and corrosion resistance, making it suitable for a variety of demanding applications, including oil and gas, power generation, and water treatment.

The defining feature of this valve is its wedge-shaped gate, which moves vertically within the valve body to control fluid flow. When the valve is opened, the wedge gate is lifted completely out of the flow path, minimizing pressure drop and allowing for unobstructed flow. In the closed position, the inclined surfaces of the wedge gate tightly press against the valve seats, creating a secure, leak-tight seal. This design enables excellent shut-off performance, even under high-pressure conditions.

Operation of the cast steel wedge gate valve is typically achieved through a handwheel, lever, or an actuator for automated control. The valve's robust construction can withstand high pressures and temperatures, with pressure ratings ranging from PN16 to PN160 and temperature capabilities reaching up to 425°C. The use of cast steel ensures the valve can endure the harsh environments of industrial processes, such as the corrosive effects of certain fluids or the abrasive nature of particulate-laden media.

With its reliable sealing performance, low flow resistance, and long service life, the cast steel wedge gate valve remains a trusted choice for applications where precise flow control and isolation are crucial. Its versatility and durability make it an indispensable component in maintaining the safe and efficient operation of industrial piping systems.
