Product Description
- The SMC AS200-X785 throttle check valve is used for the safe intermediate positioning and control of pneumatic cylinders, particularly when mounted vertically.
- Typical applications include assembly automation, handling technology, packaging technology and general industrial plant.
- The valve allows for temporary stops and protects workpieces from dropping in the event of a compressed air failure. It is therefore particularly suitable for systems with high safety requirements when holding loads.
- The AS200-X785 pilot-operated throttle check valve from SMC features a robust metal housing and G-threaded connections.
- The nickel-plated brass components and NBR seals ensure high resistance to compressed air and environmental influences.
- The pilot connection allows precise control of the check valve function at variable operating pressures
