700 X Water Pump Flow Control Valve Differential Pressure Regulator Valve

Pump Control Valve

1. PRODUCT PROFILE

The 700X pump control valve is a type of pump outlet that is installed in high buildings and other feed water systems to prevent reverse flow of the dielectric valve. When the pump is about to stop the water supply, the valve slowly closes about 90 percent, preventing the water hammer and water hammer from stopping the pump. When the pump stops completely, the valve closes completely and prevents the pumping of water from the pump. Effectively protect the pump from the reflux shock. The product is an essential protective device for the export of pumps. The valve is streamlined and is designed by the solenoid valve, which is safe and reliable to prevent water hammer and water hammer. Long service life, easy installation and maintenan.

2. WORKING PRINCIPLE

When the working valve of the pump supplies water to the downstream, the solenoid pilot valve is fully opened, the needle valve is adjusted to an appropriate opening, the upstream water enters the main valve control room through the needle valve and the one-way valve, and flows out through the solenoid pilot valve. At this time, the main valve control room The pressure keeps the main valve at the proper opening and maintains normal water downstream.
When the water pump stops working, the solenoid pilot valve closes first, the main valve control room stops draining water, the pressure in the control room rises, and the main valve starts to close. When it is closed to 90%, the upper travel switch of the main valve outputs a pump stop signal, and the pump stops running. At this time, the downstream return water enters the main valve control room through the one-way valve, the pressure in the control room rises, and the main valve is closed.
