Summary of the premise of a vertical valve: I believe that everyone is still unclear about the use of JD745X multi-function water pump control valve. Today, a vertical valve is introduced for everyone. Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. It is also resistant to thermal shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is precisely because of the excellent properties of Si3N4 ceramics that it is often used to make bearings. , mechanical components such as gas turbine blades, mechanical seal rings, permanent molds.

Summary of the premise of a vertical valve:
I believe that everyone is still unclear about the use of JD745X multi-function water pump control valve. Today, a vertical valve is introduced for everyone.
JD745X multi-function water pump control valve is installed in the water supply, water supply, diving, sewage pumping station of municipal, construction, steel, metallurgy, petroleum, petrochemical, chemical, gas (natural gas), food, medicine, power station, nuclear power, water conservancy and irrigation. In the transportation system of petroleum and chemical fluids, it is automatically controlled by interlocking with the pump.
Its advantages:
One valve combines the functions of three types of electric valve, check valve and water hammer eliminator. It has low failure, tight shut-off, and reliable performance when the water pump can be stopped when the pump is stopped, the power is cut off, or the valve is closed. Such advantages can effectively improve the safety and reliability of water supply, and meet the requirements of mechanization and automation of water supply and drainage engineering equipment.
