Festo HE-3-QS Series Pneumatic Manual Control Valve, 10 Bar Maximum Operating Pressure, 60 °C Maximum Operating Temperature - HE-3-QS-6, Numeric Part Number:153475


This pneumatic manual control valve provides manual actuation of compressed-Air lines for industrial automation tasks. Intended for in-line installation, it operates as a bistable valve suitable for controlling Air flow in systems that require manual switching between flow paths. The valve is constructed from reinforced PBT and is intended for use with standard compressed-Air media, including lubricated systems where lubrication will then be required.

Features & Benefits


• Operates to 10 bar to handle typical plant supply pressures
• Withstands vacuum down to −0.95 bar for negative-pressure tasks
• Rated for ambient temperatures up to 60°C for warm environments
• Push-in QS fittings enable Compact hose connections at both ends
• Soft sealing provides reliable shut-off and leak minimisation

Applications


• Suitable for machine-tool Air supply isolation during maintenance
• Ideal for simple on/off control in pneumatic assembly fixtures
• Used with control manifolds requiring Compact push-in connectors
• Can be used for pilot switching in pneumatic control circuits

What mounting orientation is permitted for this valve?


It is designed for any mounting position and supports in-line installation with through-hole mounting where required.

Which media are acceptable and any lubricant considerations?


Compressed Air per ISO 8573-1 is specified

if lubricated Air is used, operation must remain lubricated thereafter.

How is exhaust handled during switching?


The exhaust function does not include flow control

it vents directly without adjustable metering.

What material is the valve housing and are material restrictions noted?


The housing is MADE from reinforced PBT and the materials conform to RoHS requirements.
