Installed at the municipal, construction, steel, metallurgy, petroleum, chemical, gas (gas), food, hospital, power stations, nuclear power in areas such as water, water, diving, sewage pump room and fluid conveying system in the petroleum, chemical industry, electric valve, check valve and water hammer eliminator three equipment functions into an organic whole, can effectively improve the system safety and reliability, meet the requirements of automatic control system.

1.High safety and reliability. Cavity has quick closing, slowly-closing and three kinds of measures to eliminate water hammer, and fully interlock, won't produce false action.
2. No operational control. When the pump stops, skillfully using the medium at the ends of the valve and the pressure difference as driving medium and control of the power, make the valve automatically according to the requirements of the water pump operation procedures.
3. No professional debugging. Valve action is not affected by water pressure 
and liquid level height difference and the influence of water pump flow change, to adapt to the range.
4. Basic no need maintenance, long service life.
5. The energy saving effect is obvious. Using the import side pressure into the inferior vena to support the weight of the diaphragm pressure plate and the valve stem, resistance losses small.
