Description
1" Stainless Steel Pneumatic Shuttle Valve – AASV08
The AASV08 1" Stainless Steel Pneumatic Shuttle Valve is a high-flow air-piloted axial valve designed for ON/OFF control in pneumatic automation, air logic and industrial process systems.
Featuring a large 25mm orifice and straight-through axial flow path, the AASV08 provides excellent flow performance with minimal pressure loss. Its bidirectional design allows flexible installation for air, water, vacuum, oils, gases and other compatible process fluids.
Manufactured from 304 stainless steel (CF8) as standard, with 316 stainless steel (CF8M) available as an option, the valve operates from 0 to 16 Bar and can be configured for normally closed, normally open or double acting operation.
Valve Function & Operation
The AASV08 is a 2/2-way pneumatically operated axial shuttle valve for automatic isolation and control of liquids and gases.
The standard configuration is normally closed, with normally open and double acting configurations also available.
The valve is operated 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: 1" BSP
Alternative connection options include:
✓ BSPT
✓ NPT
✓ Flanged connections
Pilot connection: 1/8" BSP
The range of connection options allows the valve to be incorporated into threaded and flanged industrial process systems.
Pressure & Flow Performance
Operating pressure: 0 to 16 Bar
Orifice: 25mm
Water flow: 253 L/min at 1 Bar ΔP
Maximum media viscosity: 600 cSt
The large 25mm flow path provides high flow capacity while the axial valve design helps minimise pressure losses through the assembly.
Bidirectional Axial Flow Design
The AASV08 uses a straight-through axial flow path, reducing unnecessary changes in fluid direction through the valve.
This provides improved fluid dynamics with minimal pressure drop and loss of flow, making the design particularly useful where maintaining system flow efficiency is important.
Bidirectional operation also provides greater flexibility when designing process pipework and automated fluid control systems.
Construction & Materials
Standard body: 304 Stainless Steel CF8
Optional body: 316 Stainless Steel CF8M
Internals: 304 Stainless Steel CF8
Standard seals: FKM / Viton
Optional seals: EPDM
The stainless steel construction provides mechanical strength and corrosion resistance for demanding pneumatic and industrial process 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, the AASV08 can be used with:
✓ Vacuum
✓ Air
✓ Compressed air
✓ Compatible gases
✓ Water
✓ Most compatible oils
✓ Compatible process fluids
Fluids with viscosities up to 600 cSt can be accommodated.
For aggressive chemicals, fuels or specialist gases, compatibility with the selected stainless steel and elastomer materials should be confirmed before ordering.
DIN EN 12266 Class A Leakage
The AASV08 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 reliable closure and minimal leakage are important to system operation.
Optional Magnetic Position Feedback
Optional magnetic switches provide open and closed valve position feedback, allowing the actual valve position to be monitored by a PLC, relay or industrial control system.
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 positive valve-position monitoring rather than relying solely on the pneumatic command signal.
Typical Applications
✓ Pneumatic control systems
✓ Air logic systems
✓ Industrial automation
✓ Compressed air systems
✓ Water control systems
✓ Vacuum applications
✓ Oil and lubricant systems
✓ Process fluid control
✓ OEM machinery
✓ Automated process equipment
Why Choose the AASV08?
The AASV08 combines a large 25mm orifice and 253 L/min water flow with a compact 1" stainless steel axial valve design.
Its 0–16 Bar operating range, bidirectional flow capability and low pressure-drop flow path make it a strong alternative to conventional pneumatically actuated valves where high flow and compact dimensions are important.
With 304 or optional 316 stainless steel construction, FKM or EPDM seals and optional open/closed position feedback, the valve can be configured for a broad range of industrial automation duties.
