700X Water Pump Control Valve Product Description:

700X pump control valve consists of the main valve, solenoid pilot valve, needle valve, ball valve, check valve, travel switch, microfilter and pressure gauge hydraulic control system to take over. Pump to stop working, the first by the import pressure to close the main valve 90%, the pump stopped running. The remaining 10% is turned off by the backwater. Water hammer can prevent the phenomenon.

This product uses solenoid pilot control, no other devices and energy. Save energy, easy maintenance, stop the pump steady. Solenoid valve can be AC 220V or DC 24V.

This series of valve products are widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.

700X Water Pump Control Valve works:

When the pump work to the downstream water supply valve, the solenoid valve fully open, the needle valve adjusted to a suitable opening, the upstream water through the needle valve, check valve into the main valve control room, the electromagnetic pilot valve outflow, when the main valve control room The pressure to maintain the main valve at a suitable opening, to maintain normal downstream water supply.

When the pump stops working, solenoid valve first closed, the main valve control room to stop drainage, control room pressure, the main valve began to shut down. When closed to 90%, the main valve upper limit switch output stop pump signal, the pump stops running. At this point the downstream backwater through the one-way valve into the main valve control room, control room pressure, the main valve is closed.
