Main Features & Benefits |
1). Hydraulic control check butterfly valves opened by
hydraulic-driven and closed by counter-weight’s potential energy
provides excellent and reliable operation. 2). The valve is installed behind the pumps and served as both gate valve/butterfly valve and check valve with only *0% flow resistance coefficient of above two kinds of valves. It provides significant energy saving. 3). The operation of hydraulic actuator is divided into two steps of quick closing from *0° to *0° and slow closing from *0° to 0°. The closing speed and angle can be adjusted according to working condition to prevent excessive water hammer. 4). The above three models of valves can be operated manually when power failure. 5). HD**3X valve features in auto-resetting. When the valve opening reduces by *5°, the oil pump starts and make the counter weight return to original position. 6). HD7BT*3X Features in: A. The valve closing is divided into two steps of quick closing from *0°ï½ž*0° in 5～*0 seconds and slow closing from *0°ï½ž*0° in *0～*0 seconds. B. Pressure Retaining The hydraulic actuator is equipped with an energy accumulator storing with pressure oil to compensate pressure when leak occurs. C. Standby Resetting Device |
