■700X pump control valve product introduction:
The 700X pump control valve consists of a main valve, solenoid pilot valve, needle valve, ball valve, check valve, stroke switch, micro filter and pressure gauge to form a hydraulic control take-over system. When the pump needs to stop working, the pump will stop running after the main valve is closed 90% by the inlet pressure. The remaining 10% is closed by backwater. It can prevent water hammer from happening.
This product is controlled by a solenoid pilot valve and does not require additional equipment and energy. Energy saving, easy maintenance, and smooth pump stop. The 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 working valve is supplied to the downstream, the electromagnetic pilot valve is fully opened, the needle valve is adjusted to the appropriate opening degree, the upstream water enters the main valve control room through the needle valve and the check valve, and flows out through the electromagnetic pilot valve. At this time, the main valve control room The pressure maintains the main valve at the proper opening to maintain normal downstream water supply.
When the pump stops working, the solenoid valve closes first, the main valve control room stops draining, the control chamber pressure rises, and the main valve begins to close. When it is closed to 90%, the main valve upper stroke switch outputs the 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 control chamber pressure rises, and the main valve is closed.
