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¡Ü200¡æ,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.
