manualhydraulicfor control

Designed to stabilize and reduce pressure in the water supply network, thereby protecting pipeline and equipment connected to it from high pressure. Operating principle CLOSED upward flow of water presses on the outer chamber of the hose, brings the hose into hydraulic balance and closes the flow by pressing of the sleeve on the center saddle. WHILE OPENED water pressure is released from the sleeve chamber, allowing the valve to open. MANUAL CONTROL All valves are equipped with a three-way manual selector valve. Manual OPEN / CLOSE control is used to open or close. the valve. The flow through the valve is controlled by a rubber sleeve, which is driven by hydraulic pressure. The valve is positioned either in the full open or closed position. AUTO position on the selector does not affect valve control, but is used, when the valve is equipped with automatic control.
