The shut-off valve protects the operator and compressed air installation in the event of a breakdown (e.g. when air line or hose breaks).
Meets the requirements of:
Principle of operation
When the air flows through the valve it is moderated by longitudinal grooves on the outer side of the piston (1). When the flow rate is too high, the air cannot flow through the piston fast enough, so it forces the piston against the spring (2) towards the socket (3). The maximum air flow rate is factory pre-set and is basically set to allow normal air consumption when using pneumatic tools. In the event of a breakdown or malfunction (when the air flow rate exceeds the set maximum value) e.g. when the hose breaks, then the air supply is immediately shut off. The valve instantly shuts down but still allows some residual air out the damaged part of the installation.
