Product Description
- The SMC AS301FS-A throttle check valve is used for the precise control of cylinder movements in confined installation spaces.
- It is suitable for control cabinet and panel mounting in sectors such as mechanical engineering, automation technology and packaging systems.
- Thanks to its PTFE coating, the valve is ideal for use in pneumatic systems in the electronics or food industry, and in applications involving high switching frequencies or aggressive media.
- It is ideal for applications involving frequent operation and a high need for adjustment.
- The AS301FS-A air-operated throttle check valve from SMC is equipped with an integrated panel mounting, a practical digital display, an additional PTFE coating and a swivelling plug-in connection.
- The large, easy-to-grip adjustment knob allows for precise regulation and locking of the flow rate.
- The pressure lock ensures that the setting is securely locked in place during operation.
- Several throttle check valves can be easily grouped together and secured as a single unit.
