Characteristice:
This valve line can replace dome valves, tuming valves. Bel valves and double-disc valves as feeding gates of storehouse pumps, or be used as an on-off for pipelines containing abrasive dry ash, water granulated slag and the like in mines. Chemical engineering and soon, Its working nominal pressure is 1.0MPa applicable temperature, applicable temperature¡Ü200¡æ,and airsupply pressure 0.6-0.8MPa.
After the valve is closed, it¡¯s fully sealed in any direction. Its body and bonnet are made of WCB steel or stainless steel casting, Its sealing surface adopts a hard serling 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.
