Butterfly valve is a simple control valve, but also can be used for low pressure pipe switch control medium. Butterfly valve is closed parts (valve flap or disc) to disk, around the valve axis to achieve the opening and closing a valve in the pipe and the throttle cut off from the main use. Butterfly valve open and close a disk-shaped pieces of the disc, the valve body rotating around its own axis, so as to achieve the purpose of hoisting or regulation. Butterfly valve fully open to fully closed is usually less than 90 °, butterfly valves and butterfly bar itself is not self-locking capability, in order to position the disc to install the valve stem worm reducer. With worm reducer, not only to make the disc has a self-locking capability, so the disc to stop at any position, but also to improve the operability of the valve. Industry-specific characteristics of butterfly valves to high temperature and higher applied pressure range, the valve nominal diameter larger body with carbon steel, valve plate to replace rubber seal ring with metal ring. Large butterfly valve with high temperature of steel plate, mainly for high-temperature medium Flue and gas pipelines.
