V511 Vertical Pump Control Valve is designed to put into use and unmount the pumps without damaging the system. Tee fitting is provided. When the system is off, the valve is on. When the system starts, the valve enables water to flow by closing itself gradually. The control of these valves can be maintained by a control device, intermittent relay, switch, PLC control unit, etc.
Connect the signal pipe and orifice plate sent together with the valve to the network as it is shown in user’s manual. Move the three-way globe valve on the valve to automatic mode. Open the protection cap of the three-way pilot on the valve. If the flow passing through the valve is insufficient, boost the flow by screwing the adjusting bolt. If the flow passing through the valve is more than demanded amounts, reduce the flow by loosening the adjusting bolt.
