Aluminium relief valves, suitable for compressed air and gas.


Relief valve for pressure up to 15 bar (217,5 psi).
Inlet and outlet connections:
VSF130 LL 1” 1/2 – F
VSF130/2 LL 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 piston.
The product complies with the directive 2014/68/EU PED
