Description & Features
Cast steel wedge gate valve is a device widely used in petrochemical, thermal power plants and other water, oil, steam pipelines for connecting or cutting off the medium in the pipeline opening and closing. Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the flow. Gate valves usually have a minimum pressure drop when fully open, provide tight shut-off when fully closed, and remain relatively free of contamination buildup.
● Compact structure, reasonable design, good valve rigidity, smooth passage and small flow coefficient.
● The sealing surface is made of stainless steel and hard alloy with long service life.
● Flexible graphite packing, reliable sealing, light and flexible operation.
● Welding seat rings or Renewable seat rings.
● Low torque design, smooth surface stem.
● Standard ISO top mounting for easy assembly of any type of actuator or bevel gear.
● Available options: wedge vent hole or over pressure pipe, by-pass, limit switch in open or closed position.
