Pneumatic Ceramic Feed Valve(GZD644TC)

Characteristics:
This valve is applicable for discharge and transportation of dry ash systems in power plants and storehouse pumps, or can be used as an on-off device for pipelines containing abrasive dry ash, water (such as cinder water ) and the like in mines, paper making, chemical engineering and so on, as an on-off for pipelines with both soft grains and corrosive media. Its working nominal pressure is 1.0MPa, applicable temperature is below 200 Deg C, and air supply pressure is 0.6-0.8MPa.

After the valve closed, it's fully sealed in any direction. Its middle body adopts WCB steel casting and seamless steel pipe welding. Its sealing surface adopts a hard sealing element.

Its feed inlet is fully through without any blocks, and it has an automatic compressed air anti-blcikage blowing unit, with strong abrasion resistance, a good sealability, a small starting load and with  little ash sezure of accumulation.

It adopts a high-grade toughened structural ceramic seal, featuring high mechanical strength, strong abrasion resistance, a long service life and a compact structure, which can be installed at any angle.

Special ceramics is different from general ceramics, its hardness even more than steel,
second only to diamond, and corrosion resistant, high temperature resistant!!!!! "" metal
valve with long easy to produce the gap, ceramic valve is not. Because of wear-resisting,
anti-corrosive, sealing strong, ceramic water valve very water saving. "" our valves can be
used 500000 times, if every switch 60 times, can use 22.8 years, this is metal valve can not do it. "
