Product Features
2/2 Way On-Off Fluid Control
The PU225 Series is designed for automatic on-off control in fluid and compressed air systems. Its 2 port 2 position structure opens or closes the flow path by electrical signal, making it suitable for general industrial control applications.
Pilot Operated Large Flow Design
The pilot operated structure supports larger flow capacity than many small direct acting valves. It is suitable for pipelines and equipment that require stable switching for air, water, oil, and compatible neutral fluids.
Wide Port Size Range from 3/8″ to 2″
The PU225 Series covers multiple port sizes, including 3/8″, 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, and 2″. Customers can select the correct size according to pipeline diameter, flow demand, pressure range, and installation space.
Normally Closed Control Function
The valve is normally closed when the coil is not energized and opens when powered. This function is widely used in fluid control systems where the default state should keep the pipeline closed.
Suitable for Air, Water, and Oil Systems
The valve can be used for air, water, oil, and compatible neutral fluid applications. Medium compatibility, viscosity, temperature, pressure, and seal material should be confirmed before ordering.
OEM and Distributor Supply Friendly
HOMIPNEU supports model confirmation, bulk orders, export packaging, and OEM supply for solenoid valve distributors, fluid control equipment builders, and industrial automation customers.
Applications
Water Control Systems
Used for automatic on-off control in water supply equipment, washing systems, cooling circuits, irrigation systems, cleaning machines, and general water control pipelines.
Compressed Air Systems
Suitable for opening and closing air lines in pneumatic equipment, compressed air circuits, air supply systems, and automated machine control panels.
Oil and Neutral Fluid Circuits
Applied in compatible oil and neutral fluid systems where electrical on-off control is required. Fluid viscosity, seal material, temperature, and pressure must be checked before installation.
Industrial Fluid Control Equipment
Used in fluid control panels, process equipment, machine tools, packaging equipment, filling systems, and maintenance replacement projects.
OEM Machinery and Distributor Stock
Suitable for OEM equipment builders, spare parts programs, solenoid valve distributors, and customers who need multiple port size options for different pipeline systems.

FAQ
What is the PU225 Series solenoid valve used for?
The PU225 Series is used for 2/2 way on-off control of air, water, oil, and compatible neutral fluids in industrial equipment, water systems, air systems, oil circuits, and OEM machinery.
Is the PU225 Series a normally closed valve?
Yes. The PU225 Series is commonly used as a normally closed solenoid valve. The valve stays closed when the coil is not energized and opens when power is applied.
What does 2/2 way solenoid valve mean?
A 2/2 way solenoid valve has two ports and two positions. It controls whether the fluid path is open or closed.
Is the PU225 Series direct acting or pilot operated?
The PU225 Series uses a pilot operated guide type structure. This design is suitable for larger flow control applications, but the working pressure and pressure differential should be checked before use.
Can the PU225 Series be used for water?
Yes. It can be used for water control when the pressure, temperature, thread type, installation direction, and seal compatibility match the application.
Can the PU225 Series be used for oil?
Yes. It can be used for compatible oil applications, but the oil viscosity, temperature, pressure, and seal material must be confirmed before ordering.
What should be confirmed before ordering?
Please confirm the model, port size, thread type, voltage, working medium, pressure range, temperature range, viscosity, seal material, installation direction, and order quantity.
Does HOMIPNEU support OEM or distributor orders?
Yes. HOMIPNEU supports OEM and ODM orders, bulk supply, private label packaging, export cartons, and model confirmation for solenoid valves and related pneumatic components.
