Product Model
hgl-1/8-qs-6

Selling Points
- 1The Festo HGL-1/8-QS-6 piloted non-return valve is built to last, ensuring reliable operation in various pneumatic systems.
- 2This valve allows air to flow only when a signal is present at the pilot signal port, making it suitable for safety-related systems.
- 3The valve can be mounted in any position using a screw-in method with an external male thread, providing flexibility in installation.
- 4The moderate corrosion resistance ensures the valve performs well in environments where some level of corrosion is expected.
- 5The compact design and use of NBR seals make the valve suitable for lubricated air systems, ensuring smooth operation and durability.
