79 series pneumatic cut-off valves

brief introduction

In passive state, the valve is closed under the action of spring force (NC). When the actuator is subjected to external force, the piston and connecting rod are pushed, and the valve is opened. The valve can also be applied to the reverse function (NO). It can also provide a double acting actuator.
