BFDZ701XThe hydraulic control valve can be used at the outlet of centrifugal pump, with 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 computer centralized control.
major function

Small resistance: using directional valve control technology, large valve plate has high opening degree and low resistance,
The resistance coefficient is 0.3-1.1; the volume is small: the butterfly structure is adopted for the valve body, and the volume is only 1 / 3-1 / 5 of that of the multi-function hydraulic control valve with the same diameter
Light weight: the weight is only 1 / 3-1 / 5 of that of multi-function hydraulic control valve
Long service life: oblique sealing amplitude is adopted, with automatic compensation function for wear of sealing surface, and service life is greatly prolonged
Automatic control: the valve and water pump are interlocked through the medium in the pipe, and the pump valve is linked without manual intervention. The pump valve is opened and the pump stop valve is closed
Energy saving and consumption reduction: it is driven by medium pressure without external power supply, which can save energy and reduce consumption; good sealing: the double sealing technology of soft and hard combination is used to effectively solve the sealing problem of large diameter valve, which can ensure "0" leakage for a long time; easy opening and closing: the large valve plate adopts eccentric structure, with small friction torque and easy opening and closing; Easy maintenance: the control system components are outside the valve body, easy to debug, easy to maintain, online maintenance.
