ZJ745X Multifunctional Water Pump Control Valve

The ZJ745X multifunctional water pump control valve designed by Dazhong Valve Group is used in the direct water supply and drainage system of industrial and mining, enterprises and high-rise buildings. It has four functions: globe valve, check valve, electric valve and water hammer eliminator. It is especially suitable for supporting automatic control system. It does not need electrical controller and external power. It opens and closes automatically according to the conventional method. It has three functions of quick closing, slow closing and energy absorption cavity to prevent and eliminate water hammer, which can effectively improve the safety and reliability of the system. . Meet the system engineering equipment automation control requirements.

Automatic control, start the pump at light load: Affected by the pressure in the control room, when starting the pump, the main valve opens slowly, thus controlling the start of the pump load due to excessive flow, and eliminating the water hammer.
High safety and reliability: The water hammer elimination device is interlocked with the valve opening and closing action, and it has three measures to eliminate water hammer, namely quick closing, slow closing and absorption.
No need for operation control: when the pump starts and stops, the medium at both ends of the valve and its pressure difference are cleverly used as the driving medium and control power, so that the valve can automatically act according to the requirements of the pump operating procedures.
No need for professional debugging: the valve action is not affected by the hydraulic height difference, the outlet pressure and the change of the water pump flow, and has a wide range of adaptability.
Basically no maintenance, long life.
The energy saving effect is obvious: the pressure at the inlet end is used to enter the lower cavity to support the weight of the diaphragm platen and valve stem, and the resistance loss is small.
