The function of valve body:
1. Switch type：The inside coil of the battery valve is energized by a certain current or voltage, and then the internal needle valve or ball valve is driven to displace, thereby blocking or opening the oil way, which mostly is used to control the shift.
2. Impulse type：Current duty cycle control through the frequency, which is used to adjust the oil pressure
The classification of the check valve:
It can be divided into the lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into the vertical one and the straight-through one. The swing check valve can be divided into the single-lobe type, double-lobe type and peel-type. The butterfly check valve can be divided into the butterfly single-lobe type and the butterfly double-lobe type.
Matters needing attention in installation of the check valve:
1. Do not allow the check valve to bear the weight in the line pipe. It should be independently supported so that it is not affected by the pressure produced by the piping
2.Pay attention to the medium flow direction should be the same to the medium flow arrow logo on the valve body.
3.The vertical lift check valve should be installed on the vertical pipe.
4.The horizontal lift check valve should be installed on the horizontal pipe.
