Product Features
Manual Pneumatic Operation
The valve controls air direction through a handle, lever, or push-pull action without electrical actuation.
Direct Operator Control
Manual control is useful where maintenance, setup, testing, or simple machine operation requires local switching.
Directional Air Switching
The valve can route compressed air to actuator ports according to the selected handle position.
No Coil Wiring Required
Manual valves reduce wiring needs and can simplify small pneumatic control circuits.
Industrial Valve Supply
The 4H Series can be supplied for automation equipment, machine panels, maintenance replacement, and OEM pneumatic systems.
OEM and Distributor Support
HOMIPNEU supports model confirmation, bulk supply, private label packaging, and export orders for pneumatic and fluid control valves.
Applications
Manual Cylinder Control
Operators can use the valve to manually control pneumatic cylinder movement without wiring a solenoid coil.
Maintenance and Test Fixtures
Manual valves are useful for test benches, maintenance points, and fixtures that need direct operator control.
Simple Pneumatic Panels
The valve can be installed in compact pneumatic panels for local air direction switching.
Machine Setup and Adjustment
Manual control helps during setup, adjustment, or troubleshooting of pneumatic equipment.
OEM Equipment Controls
Equipment builders can use manual valves for machines that require local operator actuation.

FAQ
What is the 4H Series used for?
It is used for manual directional air control for pneumatic circuits in pneumatic, fluid control, actuator, machine panel, or industrial automation systems.
What should I confirm before ordering?
Confirm way and position type, port size, handle style, flow rate, working pressure, mounting space, and operator access, as well as order quantity, packaging requirement, and the equipment or circuit where the valve will be installed.
How do I choose the correct valve function?
Select the valve according to the circuit requirement. A 2 way valve is used for on-off flow control, while 3/2, 5/2, or 5/3 valves are used for pneumatic actuator direction control.
Why does a solenoid valve leak or switch slowly?
Common causes include dirty media, wrong pressure range, incorrect voltage, damaged seals, blocked exhaust, wrong port connection, unsuitable medium, or incomplete switching.
Can the same valve be used for both air and water?
Only when the body material, seal material, pressure range, temperature range, and valve design are suitable for both media. Always confirm the specification before use.
Can HOMIPNEU support OEM purchasing?
Yes. HOMIPNEU can support OEM and distributor orders with model confirmation, custom logo, private label packaging, export cartons, and sourcing support for complete pneumatic systems.
OEM & ODM Support
HOMIPNEU provides OEM and ODM support for pneumatic solenoid valves, manual valves, directional control valves, brass water valves, NAMUR valves, and related air control components. Services can include model matching, custom logo, private label packaging, export cartons, distributor supply, and sourcing support for complete pneumatic systems. Buyers can provide the model, port size, voltage, valve function, working pressure, medium, connector type, application environment, and expected quantity so the correct product can be confirmed for production, maintenance, or resale.
