Block valve pressure gauge, Bushing - taps, made of bright brass, G 3/8, PN 16 bar, AF 22, max. 50 °C
It is useful to install a stopcock as a shut-off element between the pressure gauge and the pipe.
When the lever is set to the »blow out« position, the medium is discharged into the atmosphere.
Stopcocks with a test port allow pressure gauges to be simultaneously connected to the pipe.
