Product Features
2/2 Way Pneumatic On-Off Control
The Q22HD Series uses a two-port, two-position structure to open or close the flow path in industrial pipeline systems. It is suitable for applications that require straightforward on-off control rather than directional cylinder control.
Air Operated Piston Structure
The main valve is actuated by a compressed-air control signal. This pneumatic operating method separates the pilot control circuit from the primary fluid passage and is suitable for automated pipeline switching.
G1/2 to G2 Port Range
The series includes Q22HD-15, Q22HD-20, Q22HD-25, Q22HD-35, Q22HD-40, and Q22HD-50 models, covering common threaded pipeline sizes from G1/2 to G2.
Suitable for Air and Compatible Fluids
Commonly listed media include compressed air, water, oil, liquefied gas, and free-flowing low-viscosity fluids. Final compatibility depends on body material, seal material, pressure, temperature, and the properties of the medium.
Brass Body for Industrial Pipeline Use
The commonly documented Q22HD configuration uses a brass valve body with a compact pneumatic actuator. Thread options may include G, BSP, or NPT depending on the supplied version.
No Main Electrical Coil Required
The valve is actuated by a pneumatic pilot signal rather than a coil mounted directly on the main valve body. An external pilot solenoid valve may still be used when electrical automation control is required.
Applications
Compressed Air Pipeline Control
Used to open and close compressed-air supply lines, branch circuits, process-air systems, testing equipment, and industrial utility pipelines.
Water Control Systems
Suitable for water supply, drainage, washing equipment, cooling lines, filtration systems, and other automated water-control applications when the materials and seals are compatible.
Oil and Low-Viscosity Fluid Control
Applicable to compatible oils and free-flowing fluids after confirming viscosity, seal material, pressure, temperature, and flow requirements.
Gas and Process Equipment
The series may be selected for compatible gases or liquefied-gas systems only after confirming material compatibility, leakage requirements, pressure conditions, and applicable safety standards.
Industrial Automation Machinery
Used in cleaning equipment, process machinery, fluid delivery systems, packaging machinery, and production lines that require pneumatically controlled pipeline isolation.

FAQ
What is the Q22HD pneumatic control valve used for?
The Q22HD Series is used for pneumatically controlled on-off switching of air, water, oil, gas, and compatible low-viscosity fluids in industrial pipelines.
Is the Q22HD a 2/2 way valve?
Yes. It has two main ports and two operating positions, providing a basic open-or-closed flow path.
Is the Q22HD an electric solenoid valve?
The main Q22HD valve is pneumatically actuated. It does not require a coil directly on the main valve, although an external solenoid pilot valve can be used to control its air signal.
What models are available?
Common models are Q22HD-15, Q22HD-20, Q22HD-25, Q22HD-35, Q22HD-40, and Q22HD-50, with main ports from G1/2 to G2.
What pilot connection does the valve use?
Common versions use a G1/8 pneumatic pilot connection. The actual thread standard should be confirmed before ordering.
Can the valve control water and oil?
Yes, provided the medium is compatible with the brass body and selected seal, and the pressure, temperature, viscosity, and flow conditions remain within the rated range.
Is the Q22HD normally closed or normally open?
Normally closed versions are common, and some product literature also shows alternative configurations. The required valve state should therefore be confirmed by model and ordering code.
What should be confirmed before ordering?
Confirm the model, port size, thread standard, normally closed or normally open function, pilot pressure, medium, operating pressure, temperature, seal material, required flow, and installation direction.
Does HOMIPNEU support OEM and distributor orders?
Yes. HOMIPNEU supports OEM and ODM supply, bulk orders, export packaging, private-label requirements, and specification confirmation for Q22HD pneumatic control valves.
