Product Features
2/2 Way Pneumatic Air Control
The 2Q Series uses a 2-port, 2-position structure for pipeline on/off control. Instead of an electric coil, the valve is controlled by pneumatic pilot air, making it suitable for air-driven control systems.
Pneumatic Pilot Operation
The valve is opened or closed by an air control signal. This design is useful in pneumatic-only systems, air signal circuits, equipment without electrical control, and applications where electrical switching is not preferred.
Suitable for Air, Water, Oil and Gas
The 2Q Series can be used for compatible air, water, oil, gas, and other neutral fluids under proper pressure, temperature, and material compatibility conditions.
Multiple Port Sizes Available
The series covers common pipeline sizes from 1/2″ to 2″, making it suitable for medium and larger flow control applications in industrial fluid systems.
High Flow Capacity Options
With available apertures from 16mm to 50mm, the 2Q Series provides different flow capacities for equipment that requires stable on/off control of fluid or gas pipelines.
No Solenoid Coil Required
Unlike electric solenoid valves, the 2Q Series does not require voltage selection or electrical wiring for actuation. It is controlled by compressed air, which can simplify some pneumatic control layouts.
Threaded Pipeline Connection
The threaded port design supports straightforward installation in air lines, water systems, gas lines, oil circuits, cleaning equipment, filling machines, and industrial automation equipment.
Practical Choice for Pneumatic On/Off Control
The 2Q Series is suitable for systems where pipeline flow needs to be controlled by air pressure signals instead of electrical signals, especially in pneumatic-driven equipment and industrial fluid control systems.
Applications
The 2Q Series air control valve is widely used in compressed air pipelines, water supply systems, oil circuits, gas control lines, cleaning equipment, filling machines, petrochemical equipment, coating machinery, vehicle equipment, packaging systems, wastewater treatment, and general industrial fluid control systems.
It is especially suitable for applications where air, water, oil, gas, or compatible neutral fluid needs to be opened or closed by a pneumatic pilot signal. For pneumatic cylinder direction control, a 5/2 way pneumatic directional valve such as 4V210-08, 4A210-08, or 4H210-08 is usually more suitable.

FAQ
What is the 2Q Series air control valve used for?
The 2Q Series is mainly used for pneumatic pilot on/off control of air, water, oil, gas, and other compatible neutral fluids.
Is 2Q Series a solenoid valve?
No. The 2Q Series is more accurately described as an air control valve or pneumatic pilot valve. It is controlled by compressed air, not by an electric solenoid coil.
Is 2Q Series a 2/2 way valve?
Yes. The 2Q Series is commonly used as a 2-port, 2-position valve for pipeline on/off control.
What media can 2Q Series control?
It can control compatible air, water, oil, gas, and neutral fluids, depending on pressure, temperature, seal material, and valve body material.
What port sizes are available for 2Q Series?
Common models include 1/2″, 3/4″, 1″, 1-1/2″, and 2″ pipeline connection sizes.
What control pressure does the 2Q Series need?
The common control pressure range is 0.3–0.6MPa, depending on the actual model and working conditions.
Can 2Q Series be used for pneumatic cylinder direction control?
It is not the best choice for standard pneumatic cylinder direction control. For double-acting cylinders, a 5/2 way directional valve is usually more suitable.
What is the difference between 2Q Series and PU220 Series?
The 2Q Series is pneumatically controlled by pilot air, while the PU220 Series is electrically controlled by a solenoid coil. Both can be used for fluid on/off control, but their control methods are different.
