Current limiting check valve Description: Current limiting check valve is mainly used for parallel installation of multiple pumps and pump pressure outlet, from the pump to limit the work flow, to prevent the pump back to the role of reflux. Current limiting check valve function and role: 1, the current limiting function The valve is installed at the pump outlet, in the single-pump start and non-full design work pump work, more work from the pump to limit the flow of the role of the pump in the higher efficiency state Under work 2. To prevent the motor love pump low head, high flow, low efficiency, overload occurs; to prevent over-rated current burning phenomenon, at the same time play a certain energy-saving effect. Current limiting check valve works: Current limiting check valve based on pump design conditions lift, pilot valve automatically detects and controls the actual working lift of the pump to limit the pump's work flow and limit the load on the motor. The valve to set a control working gas lift, when the pump head is lower than the control lift valve to do the valve action, so that the actual working lift increased; flow check valve when the pump head lift is greater than the set lift valve wide open, Valve resistance is minimal. The setting of control gas lift can be set according to the rated current of the motor, or set by the high efficiency working condition. The setting value of the working lift of the valve is adjustable, and the general factory setting is the head of the design working condition. The check function of the current-limit check valve is exactly the same as that of the micro-check slow check valve, and no closing noise and zero return current. This valve is mainly used for multi-pump installed in parallel with the use of pump pressure outlet, from the pump to limit the work flow, to prevent the pump back to the role of reflux. The valve adopts pilot valve - main valve structure, compact structure, light weight.
