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≤200℃,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.
