With worm reducer, not

only can make the disc with self-locking capability, so that the disc stops at any position, but also to improve the operational

performance of the valve. Industry-specific characteristics of Butterfly valve valves to high temperature, for higher pressure range, the

valve nominal diameter of large, carbon steel valve body, valve plate rubber seal with metal ring instead of ring. Large-scale manufacture

of high temperature valve welded with steel plate, the main medium for high-temperature air duct smoke and gas pipelines.
Butterfly

valve benefits
Butterfly valve valves open and close easily and quickly, saving, small fluid resistance, can often operate, simple

structure, small size, light weight, can carry mud accumulation of fluid in the pipe outlet at least, low pressure, can achieve a good

seal, adjusting performance,
Valve defects
Butterfly valve valve with pressure and operating temperature range is small, poor

sealing, the installation, the valve flap to stop in the closed position, open position to disc rotation should be determined with a bypass

valve Butterfly valve valve, Open the bypass valve opening should be preceded.
Electric Butterfly valve valve uses the integrated

structure, with features, small volume, light and pleasant, reliable performance, supporting a simple element, flow capacity, on the

temperature, clean the media, the choice of disc plus soft seal, rubber ring, PTFE ring to reduce leakage, high temperature and pressure

conditions can choose three eccentric seal body.
