Rising stem gate valves are usually made from cast or forged steel while non rising stem gate valves are more typically brass, bronze or cast iron. Its round handle rotates a threaded shaft which is attached to its center. Turning the handle will cause the stem to rise as it opens the valve and descend as it closes the valve. Casting gate valve is one of the most commonly used valves for connecting or cutting off the flow especially for medium and large diameter pipeline, has been widely used in conveying fluid pipeline water treatment, fire, gas, petroleum, chemical, shipbuilding and other projects.

Features
  • Compact structure and reasonable design offer a wide range of application.
  • Sealing surface by the fluid resistance is small, at the same time, stainless steel and carbide alloy seal has a longer service life.
  • The horizontal design at the bottom of the resilient seat is not easy to block to make the fluid can flow freely. It can be used for the severe working environment like sewage system.
  • Grooved design in a certain angle overcome the pipe connection is not coaxial caused by the deviation and solve the temperature difference caused by thermal expansion and cold contraction.
