Technical parameters:
1. Working pressure: Oil port ①: 240 bar (3500 psi); Ports ② and ③: 207 bar (3000 psi)
2. Flow regulation in the three-way mode: Range A: 57 lpm (15 gpm) Range B: 38 lpm (10 gpm)
3. Maximum input flow rate in three-way mode: Range A and B: 114 lpm (30 gpm) maximum in two-way mode
Flow rate: Range A: 53 lpm (14 gpm) Range B: 31 lpm (8 gpm) Note: To increase the two-way flow rate
Control the flow rate, refer to KPV72-20 model. Internal leakage: 207 bar (3000 psi) when the valve is fully closed
At pressure, it is 0.38 lpm (0.1 gpm).
4. Electrical characteristics: 2 voltage standards
5. Medium: Mineral oil with a viscosity between 7.4 to 420cSt (50 to 2000ssu) or synthetic oil with lubricating properties
6. Valve hole: VC12-3;

Working principle:
KPV72-30 will adjust the flow rate of oil port ③, which is not affected by the working pressure of the system. As the current in the solenoid valve increases, the output flow of KPV72-30 will also increase. Note: If the priority flow port of the equipment is closed by an external valve, and this valve is used for bypass flow control, if a small amount of leakage does not occur at the priority oil port, the bypass pressure drop will increase. Please consult the factory. Emergency manual operation: When starting, rotate clockwise for about 1 turn to reach the starting point. Continuing to rotate for about 5 more turns can achieve maximum displacement. At the end: Rotate counterclockwise for about 6 cycles until it stops in the forward direction.
