[Basic Information]

The opening and closing parts of the electric shut-off valve are plug-shaped clappers, the sealing surface is flat or conical, the valve flap moves linearly along the centerline of the fluid. Stem movement form, lifting rod (stem lift, hand wheel does not lift), there are lifting rotary rod (hand wheel with the stem rotating together, the nut is located in the valve body). Electric shut-off valve only applies to fully open and fully closed, does not allow for regulation and throttling.
 

[Valve Features]

1, Compact structure, reasonable design, good valve rigidity, smooth passage, small flow resistance coefficient.

2, the sealing surface of stainless steel and carbide, long life.

3, Flexible graphite packing, reliable sealing, light and flexible operation.

4, sub-manual, electric, pneumatic, gear transmission, structure type: elastic wedge single gate, rigid wedge single gate and double gate type.

5, Widely used in petroleum chemical industry, thermal power plants and other oil products, water vapor pipeline for access or cut off the medium pipeline opening and closing devices.


[Adaptation conditions]
 Electric valve, valve seat sealing surface using iron-based alloy surfacing or Stellite (Stellite) cobalt-based carbide surfacing made of wear-resistant, high temperature, corrosion resistance, scratch resistance Good performance and long service life, suitable for pipeline with various working conditions such as petroleum, chemical, pharmaceutical, chemical fertilizer and electric power industry whose nominal pressure PN1.6 ~ 16MPa and operating temperature -29 ~ 550 ℃, cut off or connect the pipeline medium. Drive mode manual, gear transmission, electric, pneumatic and so on.
