Product Overview
The CKD 4G2-PCS is a precision-engineered pneumatic solenoid valve from CKD Corporation, a globally recognized manufacturer of high-reliability fluid control components. Operating on a direct-acting or pilot-assisted solenoid principle, this 4G2 series valve is designed for directional control of compressed air and inert gases in industrial automation systems. The “PCS” designation indicates a specific configuration within the 4G2 family, typically featuring a compact body, a single solenoid pilot with spring return, and a 5-port 2-position (5/2) or 4-port 2-position (4/2) spool function. Its role is to precisely direct, stop, or divert pneumatic flow to actuators, cylinders, and process equipment with fast response and minimal pressure drop.

Engineering Features & Advantages
- Precision Spool & Seal Design: The 4G2-PCS utilizes a balanced spool mechanism that ensures low friction, minimal leakage, and consistent shifting even under varying pressure conditions, delivering reliable directional control for critical pneumatic circuits.
- Fast Response & High Cycle Life: Optimized solenoid and spring return design provides rapid actuation and de-actuation times, supporting high-speed automation sequences and extended service intervals in continuous-duty applications.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction that resists vibration, contamination, and temperature fluctuations commonly found in factory environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original CKD 4G2 series mounting and port standards, ensuring drop-in replacement without modification to existing manifolds or piping.
- Manual Override: Integrated manual override allows for safe system testing, troubleshooting, and emergency actuation without energizing the solenoid coil.
Typical Industrial Applications
The CKD 4G2-PCS pneumatic solenoid valve is widely deployed in heavy industrial and process automation environments, including plastic injection molding machines for mold opening/closing and ejector
