a overview of hydraulic automatic control valve, hydraulic automatic control valve can be applied to the centrifugal pump outlet, have to stop the flow, light load to start the pump, eliminate water hammer and flow control, and other functions, can effectively protect the safety of the water pump and pipeline equipment. Live can observe the valve open conditions, remote digital display, at the same time can output 4 ~ 20 mA dc current, centralized control by computer. 2. The technical characteristics of small resistance: hydraulic automatic control valve USES the directional valve control technology, the valve plate open degree is high, small resistance, resistance coefficient of 0. 3≤1. 1; Volume small, the body USES the wing structure, the volume is only with the caliber of multi-function hydraulic valve 1/3 1/5 or less; Light weight: the weight is only multi-function control Industrial Valves of water conservancy hub 1/3/1/5; Long service life: the helical seal, has the function of automatic compensation sealing surface wear greatly prolong the service life. Automatic control: the valve and pump through a pipeline medium linkage, valve linkage, without manual intervention, pump valve, pump valve closed; Energy saving: medium voltage drives, without external force, saving energy and reducing consumption; Good sealing: using soft and hard combined with double sealing technology, effectively solve the problem of large diameter valve sealing, which can ensure the '0' leak; Easy opening and closing: large valve plate adopts eccentric structure, friction torque is small, convenient opening and closing. Easy maintenance: in all parts of control system is located outside of the body, debugging is simple, easy maintenance, control system, on-line overhaul. Hydraulic automatic valve can be applied to the centrifugal pump outlet, have to stop the flow, light load to start the pump, eliminate water hammer and flow control, and other functions, can effectively protect the safety of the water pump and pipeline equipment. Live can observe the valve open conditions, remote digital display, at the same time can output 4 ~ 20 mA dc current, centralized control by computer.

The use and installation of wedge gate valve is compared with most other systems for managing the resilient seal gate valve effectively and no doubt flanged gate valve have won the race so many times.
