The operating temperature of the sealing ring of the butterfly valve

The operating temperature of the sealing ring of the butterfly valve

Soft seal butterfly valve is suitable for hot and cold water systems below 100℃. If the system requires higher temperatures, use metal sealed butterfly valves (available in systems up to 500 ° C).

Application of butterfly valve and gate valve in different application conditions

Application of butterfly valve and gate valve in different application conditions

Gate and butterfly valves are used to switch and regulate flow in pipelines. Of course, Shanghai Shanghai mega valve valve manufacturer in the butterfly valve supporting process is also a method and gate valve. According to the function and use of gate valve and butterfly valve, the flow resistance of gate valve is small and the sealing performance is good. Because the gate valve valve plate is perpendicular to the medium flow, if the gate valve is not switched in place, the medium on the valve plate will make the valve plate vibration, easy to damage the gate valve seal.

Beginners to valves often mistake the faucet for a valve. In fact, the faucet strictly belongs to the bathroom series. Valves are divided into gate valve, globe valve, butterfly valve, high pressure valve, low pressure valve, fluorine lined valve, safety valve, pressure relief valve, anti-corrosion valve, filter, check valve, pressure reducing valve, over flow valve, ceramic valve, medium pressure valve, high temperature valve, low temperature valve and so on.

Rate of various valve applications

Rate of various valve applications

Urban heating valves: In urban heating systems, a large number of metal sealed butterfly valves, horizontal balance valves and directly buried ball valves are needed. Because of these valves, the longitudinal and transverse hydraulic imbalance of the pipeline can be solved, thus achieving energy saving and heat balance.
