Description

Main characteristics and USES

1、 compact structure, reasonable design, good rigidity, smooth channel, small flow resistance coefficient.
2、 the sealing surface of stainless steel and carbide, long service life.
3、using the flexible graphite packing, reliable seal, flexible operation of the light.
4、 drive way points in dynamic, electric, qigong, gear transmission, structure: elastic wedge single ram, rigid wedge single ram and double disc type.
5、 is widely used in petrochemical, oil, steam pipeline, such as coal-fired power plants connected or truncated the medium inside the pipe opening and closing device.

As the material different, the general medium and the temperature are also different, for example when the material is carbon steel , the general medium is allowed water、 steam 、oil and the temperature is 425or less.
