Installed at the inlet of the water pump, the LH45-16 series flow-limiting check valve is mainly used in a system where multiple pumps are connected in parallel and the number of units is changed for flow adjustment. Play the role of limiting the flow of the pump and stabilizing the head. The device is equipped with a flow-limiting check valve to make the pump work in the high-efficiency area, preventing the low-lift and large-flow pump from over-cutting and burning the motor.
Performance and characteristics of flow limiting check valve:
1. Support the pump working point to run when the work efficiency is low in the high-efficiency area. 2. Limit the large flow of the pump.
Shut off the phenomenon of no water hammer 3. When the pump is stopped slowly with a slight resistance and non-return. >
4. Prevent the pump from burning out the motor when over-rated current is worn
5. Infinitely adjustable head function
6. Medium temperature: 0-150 degrees.
