Product Model
grla-3/8-qs-8-d

Selling Points
- 1The GRLA-3/8-QS-8-D one-way flow control valve from Festo features a piloted non-return function, ensuring that fluid flows in one direction only, which is crucial for maintaining system integrity and preventing backflow.
- 2This valve is equipped with a knurled screw for easy adjustment, allowing users to fine-tune the flow control according to their specific application requirements. This makes it highly versatile and user-friendly.
- 3The GRLA-3/8-QS-8-D is designed with a proximity sensor, which enhances its functionality by providing real-time feedback on the valve's status. This feature is particularly useful in automated systems where precise monitoring is essential.
- 4The valve includes a push-in T-connector and push-in L-fitting, making it easy to integrate into various pneumatic systems without the need for complex connections. This simplifies the setup process and reduces installation time.
- 5Constructed from high-quality materials, including wrought aluminum alloy for the threaded plug and NBR for the material seals, the GRLA-3/8-QS-8-D ensures durability and reliability in demanding industrial environments. It also conforms to RoHS standards, making it an environmentally friendly choice.
