The hydraulic automatic valve can be used at the outlet of centrifugal pump, which has the functions of check-in, light load start-up, elimination of water hammer and flow regulation, which can effectively protect the safety of water pump and pipe network equipment; the valve opening can be observed on site, with remote digital display; at the same time, it can output 4-20mA DC current for centralized computer control.

Product introduction and Application

Product features

1. It has the functions of check-in, light load start-up, elimination of water hammer and so on.
2. The opening and closing of the valve is driven by the conveying medium and is automatically interlocked with the water pump, so it is very convenient to operate without personnel and external force.
3. Slowly open the pump: after starting the pump, the valve can only be opened after the inlet pressure of the valve reaches the preset value, which can reduce the pump starting current and ensure the safety of the motor and electronic control system
4. The energy saving effect is remarkable: the opening and closing parts are inclined butterfly plate, the water flow is smooth, and the loss along the way and local loss is very small
5. The structure of butterfly valve has the characteristics of small volume and light weight, small space occupation and low civil engineering cost; the electro-hydraulic control system of hydraulic butterfly valve is cancelled to reduce cost, increase reliability and stability, reduce power consumption, and achieve the purpose of energy saving.
