Pneumatic stop valves by Metal Work

The STP L stop valve belongs to the LINE ON LINE® family and can be connected in series or in parallel with the other products in the same family.
It is available in a version for pipe-pipe connection, which includes two push-in fittings, and a version for thread-pipe connection, which includes a nickel-plated brass male thread and a push-in fitting.
The stop valve is normally mounted on the inlet port of cylinders and allows the flow of air only in the presence of a pneumatic pilot. Cylinder movement ceases if there is a drop in pneumatic pilot pressure
The compressed air port is a push-in fitting for Ø 4 pipe.
This stop valve is available in a unidirectional version, so the flow can be interrupted in one direction, but remains free in the other direction.
This valve can also be used as a unidirectional normally-closed 2/2 pneumatic control valve.
