Solenoid Valves (CKD)
4GA/B Series
- 3, 5-port valve
- Cylinder bore size: φ20 to φ100
Residual pressure exhaust option added
Integrated exhaust mechanism.
Residual pressure release of center closed position of a 3-position valve to relieve pressure in an emergency stop.
Rod transfer after intermediate cylinder stop for 3-position APR connection (with malfunction prevention valve).
Reliability
Superb main valve sliding mechanism realizes low sliding/long service life.
Response time 12 ±2 ms (4G1 type)
Durability count: 100 million times (single solenoid)
Improved responsivity after shutdown.
Environmental performance
Continuous energization is made possible by adopting a new coil actuator.
Reduced power consumption is also achieved. (0.35 W, 0.1 W / low exoergic / energy type
Safety
For both metal base and resin block, exhaust check valve is provided as standard.
Prevents backflow of air at the time of exhaust, preventing cylinder malfunction.
Ease of use
Wiring connector can be moved freely upwards and sideways.
As the D sub-connector is also a rotary type, it can be moved freely upwards and sideways.
4GD/E Series
- 3, 5-port standard valve
- Cylinder bore size: φ20 to φ100
Environmental performance
Reduces power consumption by adopting a new coil actuator. (0.35 W).
Helps prevent misoperation problems
For both metal base and resin block, exhaust check valve is provided as standard.
Prevents backflow of air at the time of exhaust, preventing cylinder malfunction.
Ease of use
Wiring connector can be moved freely upwards and sideways.
As the D sub-connector is also a rotary type, it can be moved freely upwards and sideways.
4GD/E ATEX
CKD has extended the 4GD / E EA valve series with ATEX valves for ZONE 1 (ATEX standard: II 2G Ex ib IIC T4 Gb).
The valve series is available in 4 sizes from 10mm to 25mm.
Valves are characterized by compactness and reliability.
3/2 valves, 2x3 / 2NC valves, 5/2 valves and 5/3 valves are available as individual or valve terminals with IP67 protection class.
