3/8" Stainless Steel Pneumatic Shuttle Valve – AASV03
The AASV03 3/8" Stainless Steel Pneumatic Shuttle Valve is a compact high-flow air-piloted axial valve designed for ON/OFF control in pneumatic automation, air logic and industrial process systems.
Featuring a 10mm orifice and straight-through axial flow path, the AASV03 delivers 75 L/min water flow at 1 Bar pressure differential while helping minimise pressure drop and flow restriction. The valve is bidirectional, providing flexible installation for vacuum, air, water, gases, oils and other compatible process fluids.
Manufactured from 304 stainless steel (CF8) with Viton/FKM seals as standard, the valve operates from 0 to 16 Bar and can be supplied in normally closed, normally open or double acting configurations.
Valve Function & Operation
The AASV03 is a 2/2-way pneumatically operated axial shuttle valve designed for automatic isolation and control of liquids and gases.
The standard configuration is normally closed, with normally open and double acting configurations also available.
Operation is provided by an external pneumatic pilot supply through a 1/8" BSP connection and NAMUR interface.
Recommended pilot pressure: 3 to 5 Bar
Maximum pilot pressure: 8 Bar
Ports & Connections
Standard process connection: 3/8" BSP
Alternative connection options include:
✓ BSPT
✓ NPT
✓ Flanged connections
Pilot connection: 1/8" BSP
Pressure & Flow Performance
Operating pressure: 0 to 16 Bar
Orifice: 10mm
Water flow: 75 L/min at 1 Bar ΔP
Maximum media viscosity: 600 cSt
The 10mm axial flow path provides excellent flow capacity from a compact 3/8" pneumatically operated valve.
Bidirectional Axial Flow Design
The AASV03 uses a straight-through axial flow path, helping minimise changes in media direction and unnecessary internal restriction.
This improves fluid dynamics and helps reduce pressure drop and loss of flow compared with more restrictive valve arrangements.
Bidirectional operation also provides additional flexibility when integrating the valve into pneumatic and process pipework.
Construction & Materials
Valve body: 304 Stainless Steel CF8
Internals: Stainless Steel CF8
Standard seals: FKM / Viton
Optional seals: EPDM
The stainless steel construction provides good mechanical strength and corrosion resistance for industrial pneumatic and fluid-control applications.
Seal & Temperature Options
FKM / Viton
Operating temperature: -20°C to +150°C
Suitable for many compatible oils, gases and industrial process fluids.
EPDM
Operating temperature: -20°C to +130°C
Typically selected for compatible water and aqueous fluid applications.
The correct seal should be selected according to the media, concentration and operating temperature.
Media Compatibility
Subject to material and seal compatibility, suitable media include:
✓ Vacuum
✓ Air
✓ Compressed air
✓ Compatible gases
✓ Water
✓ Most compatible oils
✓ Compatible process fluids
Fluids with viscosities up to 600 cSt can be accommodated.
For chemicals, fuels or specialist gases, compatibility with the stainless steel construction and selected elastomer should be confirmed before ordering.
DIN EN 12266 Class A Leakage
The AASV03 is specified to DIN EN 12266 Class A leakage, providing tight shut-off for industrial isolation and process control applications.
This makes the valve suitable where dependable closure and minimal leakage are important.
Optional Magnetic Position Feedback
Optional magnetic switches provide open and closed valve position feedback for connection to PLCs, relays and industrial control systems.
Magnetic switch specification:
✓ Open & closed position feedback
✓ Red LED status indication
✓ 10–30VAC/DC supply
✓ Maximum current 100mA
✓ Two PVC cables
✓ IP67 protection
✓ Temperature -10°C to +70°C
This provides confirmation of the actual valve position rather than relying solely on the pneumatic command signal.
Typical Applications
✓ Pneumatic control systems
✓ Air logic systems
✓ Industrial automation
✓ Compressed air systems
✓ Vacuum applications
✓ Water control systems
✓ Oil and lubricant systems
✓ Process fluid control
✓ OEM machinery
✓ Automated process equipment
Why Choose the AASV03?
The AASV03 combines a compact 3/8" stainless steel body with a 10mm orifice and 75 L/min water flow, providing high flow capacity for its connection size.
Its 0–16 Bar pressure range, bidirectional operation and low pressure-drop axial flow path make it particularly useful where compact dimensions and efficient flow are important.
Optional EPDM seals and magnetic open/closed position feedback provide further flexibility for integration into automated industrial systems.
Ordering Options
