Riktad pneumatisk reglerventil Festo R-5-1/4-B

Mechanically actuated valves are often used as "signal valves" and feed back a pneumatic signal to the controller. This feedback, e.g. "End position reached", is realised via a stem actuated valve or roller actuated valve. This is a simple application, but it is an extremely popular solution for smaller machines and conveying systems, e.g. for controlling simple clamping and locking operations in semi-automated assembly and production. The modern design with metal housing combines sturdiness and functionality.
