Aluminium high precision relief valves , suitable for compressed air and gas.
High precision relief valve for pressure up to 3 bar (43,5 psi).
Inlet and outlet connections G 2 – F by flanges screwed to the body.
The relief valve opens when the inlet pressure increases above the set point initially regulated by the adjusting screw and it closes when the pressure goes down under the set point. Set point pressure is controlled by a rubber diaphragm.
The product complies with the directive 97/23/CE PED.
