Product Features
2/2 Way Normally Closed Design
The PU220 Series uses a 2-port, 2-position normally closed structure. When the coil is not energized, the valve remains closed; when power is applied, the valve opens to allow medium flow.
Brass Body for General Fluid Control
The brass valve body provides stable strength and practical corrosion resistance for common air, water, oil, and compatible neutral fluid applications.
Multiple Port Sizes Available
The PU220 Series covers common threaded sizes from G1/8″ to G1″, making it suitable for compact equipment, medium-flow pipelines, and larger fluid control circuits.
Suitable for Air, Water and Oil Systems
This series is designed for general fluid on/off control in automation equipment, water systems, air lines, oil circuits, cleaning machines, filling equipment, and industrial pipeline applications.
Normally Closed Safety Function
The normally closed design helps shut off the flow automatically when power is removed. This is useful for systems where the default state should remain closed for safety or process control.
Optional Seal Materials
NBR, VITON, and EPDM seal options can be selected according to medium type, temperature, and application requirements.
Multiple Voltage Options Available
The PU220 Series can be supplied with common voltage options such as DC12V, DC24V, AC24V, AC110V, and AC220V to match different control systems.
Practical Choice for Automated On/Off Control
The PU220 Series is suitable for equipment that requires electric signal control of pipeline flow, especially where a compact brass valve and multiple size options are needed.
Applications
The PU220 Series normally closed brass solenoid valve is widely used in compressed air pipelines, water supply systems, oil circuits, cleaning equipment, filling machines, irrigation systems, HVAC auxiliary systems, water treatment equipment, laboratory devices, and general automation fluid control systems.
It is especially suitable for applications where air, water, oil, or compatible neutral fluid needs to be opened or closed by an electrical signal. For pneumatic cylinder direction control, a 5/2 way pneumatic solenoid valve such as 4V210-08 or 4V310-10 is usually more suitable.

FAQ
What is the PU220 Series solenoid valve used for?
The PU220 Series is mainly used for electrical on/off control of air, water, oil, and other compatible neutral fluids.
Is PU220 Series a pneumatic directional valve?
No. PU220 Series is a fluid control solenoid valve for pipeline on/off control. It is not a 5/2 way pneumatic cylinder directional valve.
Is PU220 Series normally closed?
Yes. The standard PU220 Series is normally closed, meaning the valve stays closed when the coil is not energized and opens when power is applied.
What port sizes are available for PU220 Series?
Common port sizes include G1/8″, G1/4″, G3/8″, G1/2″, G3/4″, and G1″.
Can PU220 Series be used for water?
Yes. It can be used for water if the pressure, temperature, seal material, and medium compatibility match the system requirements.
Can PU220 Series be used for oil?
Yes. It can be used for compatible light oil applications, but final selection should confirm fluid viscosity, pressure, temperature, and seal material.
What seal materials are available?
Common seal options include NBR, VITON, and EPDM. The correct seal should be selected according to the working medium and temperature.
What is the difference between PU220 Series and 2V025 Series?
Both are 2/2 way normally closed fluid control solenoid valves. PU220 Series offers a wider port size range up to G1″, while 2V025 Series is usually a compact small-flow valve with a smaller orifice.
