Product Description
This product was developed by our factory's technical personnel based on advanced similar products from both domestic and international markets. The pump control valve mainly consists of a main valve, solenoid valve, needle valve, ball valve, micro check valve, limit switch assembly, pressure gauge, etc. This valve features a novel structure, rational design, excellent sealing effect, low fluid resistance, high flow rate, and long service life. A control system with conduits for the solenoid valve and limit switch is installed on the main valve, utilizing hydraulic operation. It is commonly used in automatic control systems for water supply and drainage as well as industrial systems, offering advantages such as compact size, light weight, easy maintenance, convenient use, and safety reliability.
The water pump control valve is a kind of diaphragm hydraulic control valve, which is installed at the outlet of the water pump. It mainly plays the role of check and eliminate water hammer to protect the pipeline and the water pump.
When the pump starts, the main valve should be opened slowly to prevent the generation of sudden pressure. Before the pump stops running, the solenoid valve should be closed first. At this time, the main valve will close 90% and trigger the travel switch group, and the pump will stop running through the electronic control system to prevent the generation of water hammer by reducing the flow rate of water behind the valve.
In case of sudden power failure, the main valve will automatically close the main valve to protect the pump.
