The limit switch valves have been designed to address the constant demand for minimal space requirements without compromising performance and reliability. The "JET" version is available with M5 threaded connections or with quick-connect fittings for a pipe diameter of 4x2, allowing for a rapid connection to various users. These limit switch valves, mounted on threaded plates or with quick-connect fittings, can be combined with different actuation options for panel installation to accommodate all types of systems. An interesting application is as a control for 3/2 - 5/2 valves, in cases where sensitive actuation is necessary.
