Product Description
Cast Steel Wedge Gate Valve is a kind of gate valve. It is named because its sealing surface is at a certain angle to the vertical centerline, that is, the two sealing surfaces are wedge-shaped. It is characterized by a traveling wedge, which is moved with the operation of the stem nut. This kind of valve can withstand high pressure because the sealing surface of the valve is at a certain angle with the vertical center line, and the sealing is better. Cast Steel Wedge Gate Valve is widely used in petrochemical, thermal power plants and other water, oil, steam pipelines
Features
● The most prominent feature of Cast Steel Wedge Gate Valve is a movable wedge, which moves with the operation of the stem nut.
● Its sealing surface is made of stainless steel and cemented carbide, which makes it have a longer service life.
● It generally have minimal pressure drop when fully opened, provide tight closure when fully closed, and remain relatively free of contamination accumulation.
● Low torque design, smooth surface stem.
