Membrane valve, with fixed high-lift calibration and direct reaction spring.
The calibration screw cannot be tampered with, without causing irretrievable damage to the valve.
The shutter membrane is guaranteed non-stick type and will not alter shape after prolonged utilisation.
The calibration pressure is stamped in relief on the plug placed on top of the valve.
The possibility of the valve being opened accidentally is prevented by a protection cap.
In order to turn the knob, it is necessary to remove the cap.
The addition of a pressure gauge is alredy foreseen.
