Product Description
Multi-function hydraulic control valve is the electric valve, check valve and water hammer eliminator in one, according to the control needs to achieve water level, pressure regulation, throttling and other functions of the new valve, effectively improve the safety and reliability of the system, to meet the system process automation control requirements.
Hydraulic control valve characteristics;
1. Automatic control, light load start the pump, affected by the pressure in the control room, when the pump is started, the main valve opens slowly, thereby controlling the start of the pump load due to excessive flow, and eliminating the water hammer of the pump.
2, high safety and reliability, eliminate water hammer device and valve opening and closing action completely chain, at the same time with quick closing, slow closing, absorb three measures to eliminate water hammer.
3, no need to operate control, when the pump starts and stops, the use of the valve at both ends of the medium and its pressure difference as the driving medium and control power, so that the valve automatically according to the requirements of the pump operating procedures for action.
4. No professional debugging is required, and the valve action is not affected by the level difference, outlet pressure and pump flow changes, and has a wide range of applications.
5. The energy-saving effect is remarkable. The pressure at the inlet end is used to enter the lower cavity to support the weight of the diaphragm and the valve plate, and the resistance loss is small.
6. Convenient maintenance and long life, the valve basically requires no maintenance. When there are special circumstances, the upper cover, diaphragm seat, valve stem, slow closing valve plate can be taken out as a whole, convenient maintenance and replacement of rubber sealing ring, O-ring and other vulnerable parts.
Multi-function hydraulic control valve scope of application, mainly installed in the water supply and drainage, construction, petroleum, chemical, gas, natural gas, food, medicine, power plants, nuclear power and other fields of water, water, water, sewage, pump room and petrochemical fluid delivery system, connected to the pump outlet or other piping system as a control.
