Pneumatic ceramic feed valve WZ644TC-150LB Description

Characteristice:

This valve is applicable for discharge and transportation of dry ash systems in power plants and storehouse pump, or can be used as an on-off for pipelines containing abrasive dry ash, water(such as cinder water) and the like in mines. Papermaking, chemical engineering and so on, Its working nominal pressureis 1.0MPa, applicable temperature≤200℃,and airsupply pressure 0.6-0.8MPa.

After the valve is 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 biocks, and it has an anti blockage blowing unit, with strong abrasion resistance, a good seal ability, a small starting load and with little ash seizure or 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.
