Hydraulic Variable Displacement Vane Pump

Hydraulic Variable Displacement Vane Pump can be used when there is electricity and the working pressure P20 is 4.5MPa. 

Electric angle control valve working principle: Electric angle control valve usually uses an open flow direction. At present, in the valve market, environmental protection and noise are becoming more and more popular. The regulating valve has a higher adjustment accuracy than the automatic valve. The adjustment accuracy of the self-propelled regulating valve depends on the precision of the spring and the diaphragm of the self-propelled valve. In general, the final adjustment accuracy does not exceed 5%, and the adjustment accuracy is guaranteed at 10%

P20 working pressure is 4.5MPa when user selects electric shut-off valve. The user uses electricity as energy. under normal circumstances, particularly suitable for fiber-containing media small solid particles, slurry, etc. That can meet the requirements of the ventilation throttle valve installation, temperature change in working conditions and the melting process resulting in impenetrable media. Trapezoidal threads used for power transmission are located at the valves. Therefore, it is moderately susceptible to corrosion and cannot be used. The opening level cannot be directly observed and the display device is required. Threaded valves are most valves with a nominal diameter of less than 50 mm.

At the same time  we will in accordance with reputation first, customer first priciple, always put the customer/s interesrs first, wholeheartedly to offer each of our customers the best products and the best quality service as in the past.
