Description

1/8" Brass Solenoid Valve – SHAKO PU220AR-01


The SHAKO PU220AR-01 is a compact 1/8" 2/2 way normally closed direct acting brass solenoid valve designed for reliable control of compressed air, water, light oils and compatible neutral fluids.

Its direct acting design requires no minimum operating pressure, making the PU220AR-01 suitable for both pressure and vacuum applications. The compact 22mm wide forged brass body and low-power coil make it particularly suitable for OEM equipment, control panels, laboratory equipment and general industrial automation where installation space is limited.

Available with NBR, FKM (Viton), EPDM or HNBR seals and optional ATEX / IECEx explosion-protected solenoid operators, the PU220AR-01 can be configured for a wide range of industrial fluid control applications.

Valve Function & Operation

Function: 2/2 way normally closed
Operation: Direct acting
Port size: 1/8" BSP
Optional thread: NPT
Orifice: 1.5mm
Effective area: 1.8mm²
The direct acting construction operates from zero pressure differential and does not rely upon upstream pressure to open or close the valve.
This makes the PU220AR-01 particularly useful for low-pressure, vacuum and small-volume fluid control applications.

Pressure & Temperature

AC pressure range: 0 to 8.5 Bar
DC pressure range: 0 to 7 Bar
Proof pressure: 10 Bar
Minimum pressure differential: 0 Bar
Fluid temperature: -10°C to +90°C
Ambient temperature: -10°C to +60°C
Maximum operating pressure may vary according to voltage, coil and application conditions.

Construction & Materials

Body: Forged brass
Internals: Stainless steel
Orifice: 1.5mm
Effective area: 1.8mm²
Standard seal: NBR
Optional seals:
✓ FKM (Viton)
✓ EPDM
✓ HNBR
Installation: Any direction
Recommended installation: Horizontal
Net weight: Approximately 175g

Seal & Media Selection

Correct seal selection is important when using the PU220AR-01 with different fluids.
NBR:
✓ Air
✓ Water
✓ Neutral gases
✓ Mineral oil
FKM (Viton):
✓ Fuel oil
✓ Gasoline / petrol
✓ High-test gasoline
✓ Diesel fuel
EPDM:
✓ Air
✓ Water
✓ Gear oil
✓ Engine oil

✓ Detergent liquids
Always confirm chemical and temperature compatibility of the selected seal and valve materials before use with fuels, gases, oils or specialist process fluids.

Flow Performance

Orifice size: 1.5mm
Effective area: 1.8mm²
The compact orifice provides controlled flow for pneumatic, water and light fluid applications where a small direct acting solenoid valve is required.

Coil & Electrical

Coil type: DIN
AC power consumption: 6VA
DC power consumption: 4.8W

✓ Gas monitoring equipment
✓ Vacuum control applications
✓ General industrial automation

Compact Direct Acting Design

The SHAKO PU220AR-01 combines a compact forged brass body with simple direct acting operation for dependable fluid control from zero pressure differential.
Unlike pressure-assisted diaphragm valves, the PU220AR-01 does not require upstream pressure to operate. Energising the solenoid directly moves the internal plunger, providing quick response and making the valve suitable for low-pressure and vacuum applications.
The compact 1/8" body is particularly useful in OEM equipment, control cabinets and machinery where installation space is restricted. Despite its small size, the valve provides pressure capability up to 8.5 Bar with an AC coil and up to 7 Bar with a DC coil.
A choice of NBR, FKM, EPDM and HNBR sealing materials allows the valve to be configured for different media and temperature requirements, while optional explosion-protected ATEX / IECEx coils extend its use to suitable hazardous-area installations.

Ordering Information

Select the required seal material, thread, voltage and electrical option before adding the valve to your basket.
Available options include:
✓ 1/8" BSP thread
✓ Optional 1/8" NPT thread
✓ NBR, FKM, EPDM or HNBR seals
✓ AC and DC voltage options
✓ Optional LED connector
✓ Optional timer control
✓ Optional ATEX / IECEx coil
For fuels, gases, oxygen or unusual process media, contact us before ordering so that material compatibility and the correct valve configuration can be confirmed.
