SOLENOID-OPERATED CHECK VALVE（HK2）■Features
In the normal state this type of valve prevents the flow of pressurized fluid from aspecified direction. However, it allows control of the direction of flow as needed byelectric operation. This type of valve is mainly used for preventing a cylinder fromfalling under its own weight.
1. With the internal drain type, a back pressure of up to 14 MPa can be applied to theOUT port.
2. Reverse flow from the OUT port to the IN port is possible, if energized on the externaldrain type.
3. Continuous energization is possible with both AC and DC.
4. External oil leakage is minimized by the adoption of an oil-immersed solenoid valve.
5. A DIN connector is adopted to facilitate wiring work.
6. Water-proofing and corrosion resistance are improved.
● The switching frequency must be within 1 time/sec.
● Maintain voltage range within ±10% of the rated voltage.
● Since the cracking pressure of the check valve is 0.3 MPa, the fluid pressure must
always be higher than this value. (Fluid temperature: 20˚C or higher, equivalent toISO VG32)
