Product Description
- The SMC AS201-X785 throttle check valve regulates the supply air to pneumatic actuators and is primarily used in systems with high cycle rates or complex motion control.
- It is suitable for sectors such as mechanical engineering, assembly automation, robotics and packaging technology.
- The valve allows for temporary stops and prevents workpieces from dropping in the event of a compressed air failure, making it ideal for applications requiring precise control under varying process conditions.
- The AS201-X785 air-operated throttle check valve from SMC features a durable metal body and G-threaded connections.
- The pilot control allows the check valve function to be specifically deactivated to enable a controlled air flow even in the reverse direction.
- Nickel-plated brass components and NBR seals ensure reliability in demanding industrial environments.
