4R Series: High-Performance 5/2-Way Hand Pull Valves
The 4R series is a premier line of manually operated directional control valves. Designed for precision and ease of use, the 4R series (including the popular 4R210 and 4R310 models) provides reliable 5-port 2-position (5/2-way) control for pneumatic cylinders and actuators. Its robust "Hand Pull" mechanism is the ideal choice for manual assembly lines, testing jigs, and emergency air control stations.
Core Technical Features
Smooth Manual Actuation: The hand-pull mechanism is designed for tactile precision and smooth operation, ensuring reliable switching even in high-frequency manual tasks.
Sliding Column Structure: The internal sliding column mode provides excellent sealing performance and superior tightness, minimizing air leakage and ensuring consistent pneumatic force.
Low Friction Internal Hole: The valve body utilizes AirTAC’s proprietary internal hole processing technology, resulting in minimal attrition friction, a low starting force, and an exceptionally long service life.
Lubrication-Free Design: High-quality seals and precision engineering allow the 4R series to operate reliably without additional oil lubrication, maintaining a clean and maintenance-free system.
Multi-Directional Mounting: The compact aluminum alloy body is designed with multiple mounting holes, allowing for flexible installation in both horizontal and vertical orientations.
Standardized Porting: Available in 1/8", 1/4", and 3/8" port sizes to match standard pneumatic fittings and tubing.
