Product Features
3/2 Way Manual Air Control
The 3R210-08 hand pull pneumatic valve uses a 3-port, 2-position structure for manual air supply and exhaust control. It is suitable for simple pneumatic circuits that need direct operator control.
Normally Closed Structure
In the normal position, the air inlet remains closed while the output side can exhaust. This makes the 3R210-08 useful for air dump, pilot control, and single-acting cylinder applications.
Manual Push-Pull Operation
The valve can be switched directly by hand without electrical wiring, solenoid coils, or PLC output. This makes it practical for manual workstations, test benches, maintenance circuits, and simple pneumatic equipment.
1/4 Port for Practical Airflow
The 1/4″ port size provides suitable airflow for small and medium pneumatic control circuits, including single-acting cylinders, air pilots, clamps, and auxiliary air lines.
Compact Aluminum Alloy Body
The aluminum alloy body provides stable strength, light weight, and reliable performance in general factory compressed air environments.
Smooth Sliding Spool Structure
The sliding spool design supports smooth manual switching, stable sealing, and consistent airflow control during repeated operation.
No Extra Lubrication Required
The 3R210-08 can operate in clean compressed air systems without additional oil lubrication, helping reduce maintenance work and keep the air circuit cleaner.
Suitable for Air Dump and Exhaust Control
Compared with 5/2 way hand pull valves used for double-acting cylinders, the 3R210-08 is better suited for 3/2 way control tasks such as air on/off, signal air control, exhaust release, and single-acting actuator operation.
Applications
The 3R210-08 hand pull pneumatic valve is widely used in single-acting cylinder control, air dump circuits, pilot air control, exhaust release, manual air on/off control, pneumatic clamps, test equipment, maintenance air lines, assembly stations, packaging machinery, and simple pneumatic automation systems.
It is especially suitable for applications where an operator needs to manually control compressed air flow without using electrical signals, solenoid coils, or PLC control.

FAQ
What is the 3R210-08 hand pull pneumatic valve used for?
The 3R210-08 is mainly used for manual compressed air control, single-acting cylinder operation, pilot air control, exhaust release, and air dump applications.
Is 3R210-08 a solenoid valve?
No. The 3R210-08 is a manually operated hand pull pneumatic valve. It does not require a coil, cable, or electrical signal.
Is the 3R210-08 a 3/2 way valve?
Yes. The 3R210-08 is a 3-port, 2-position pneumatic directional valve.
Is 3R210-08 normally closed?
Yes. The 3R210-08 is commonly used as a normally closed manual air valve.
What is the port size of 3R210-08?
The standard port size is 1/4″, suitable for small and medium pneumatic control systems.
Can 3R210-08 be used for double-acting cylinders?
It is not the best choice for standard double-acting cylinder forward and backward control. For double-acting cylinders, a 5/2 way valve such as 4R210-08 is usually more suitable.
What is the difference between 3R210-08 and 4R210-08?
The 3R210-08 is a 3/2 way valve mainly used for air on/off, exhaust, and single-acting cylinder control. The 4R210-08 is a 5/2 way valve mainly used for controlling double-acting cylinders.
Does the 3R210-08 need electricity?
No. It is manually operated and can be used in pneumatic systems where electrical control is not required.
