hgl-3/8-qs-8
Selling Points
- 1The Festo HGL-3/8-QS-8 piloted check valve ensures one-way flow control in pneumatic systems, preventing backflow and maintaining system integrity.
- 2This valve is actuated pneumatically, allowing for precise control over the flow of compressed air, making it ideal for various industrial applications.
- 3Built with high-quality materials, including copper-free and PTFE-free components, the valve is RoHS compliant and resistant to moderate corrosion stress.
- 4The valve can be mounted in any position, offering flexibility in system design and installation. It also features a screw-in design with a male thread for easy installation.
- 5With a standard flow rate of 1200 l/min and a nominal flow rate of 830 l/min, the Festo HGL-3/8-QS-8 ensures efficient operation within a wide range of operating pressures (0.5 to 10 bar).
