The valve has been designed for a continuous use at a water temperature of 60°C. It can resist for short periods at a
maximum temperature of 90°C.
(2)
This is the pressure reduction necessary in comparison to the set up, in order that the valve brings back pressure in
the circuit.

- Sturdy steel and brass construction.
- By-pass control actuated at very low pressure values with
reduced pressure in the delivery line when gun is shut.
- Quick start at gun opening assures gradual pressure reset,
essential for use on endothermic engines.
- Specially designed check valve prevents jamming and vibrations
even in presence of sand and scales
- Working typology protected by registered patent.
