LH45X Flow Limit Check Valve
LH45X Flow Limiting Check Valve Structure
LH45X current-limiting check valve is installed at the outlet of the pump. When a single pump is started and a non-full design working number is designed, the working pump will limit the flow of the working pump and make the pump work at a higher efficiency. Overload occurs at head, large flow rate, and low efficiency; it prevents the phenomenon of over-rated current from burning the motor, which has a significant energy saving effect. The valve adopts a pilot-main valve structure, which is compact in structure and light in weight. The valve function is completely equivalent to a micro-resistance slow-closing check valve without closing noise and zero backflow.
- According to the design working condition of the pump, the lift head : the pilot valve automatically detects and controls the actual working head of the pump to limit the working flow of the pump and the load of the motor. This valve sets a control working gas head. When the pump working head is lower than the control head, the valve will close the valve, which will increase the actual working head.
- When the pump working head is greater than the set head, the valve is fully open : the valve resistance is extremely small. The setting of the control gas lift can be set according to the rated current of the motor, or it can also be set according to the high-efficiency working conditions. The valve working head setting is adjustable. Generally, the factory setting is the design working head.
