■Features
This valve is used to enable smooth starting and stopping by alleviating the shock generated
during acceleration/deceleration of an actuator with larger inertia.
The conventional series is modified significantly so as to allow accurate and smooth start and
stop control even with larger pressure variation in the circuit.
1. The valve smoothly controls starting and stopping of actuator that has larger inertial.
2. Since it is operated by a solenoid, the actuator can be controlled at any position without
changing the valve position.
3. The main valve switching speed adjustment dial and the stroke adjust screw allow to
adjust the acceleration/deceleration and maximum and minimum flow rates.
4. There are valves in which a pressure reducing valve with fixed pressure in a pilot circuit is
assembled, and internal drain valves.
● Use with a switching frequency within 60 times/min.
● Use the voltage within a range of ±10% of the rated voltage.
● For the solenoid characteristics, refer to page 94.
● Use the stroke adjustment screw to control the maximum or minimum flow rate.
● Specify separately when the sub-plate SHLD**-**T1 is necessary.
● The valve is compatible with the conventional valves.
● Pilot valves are as follows: HD3-2S-BcA-025B-WY**
HD3-2WD-BcA-025B-WY**
HD1-2S-BcA-025B -WY**
HD1-2WD-BcA-025B-WY**
● Since the drain is connected to the OUT port on the internal drain type valve, do not apply
back pressure to the OUT port. (Permissible back pressure: 0.3 MPa or less)
● The main valve speed adjustment dial A adjusts the time from SOLb energization to main
valve switching. The main valve speed adjustment dial B adjusts the time from SOLb
energization or de-energization to main valve’s return to home position.
