Brass relief valves, suitable for compressed air, gas and liquid.
Product
Relief valve for pressure up to 50 bar (725 psi).
Inlet and outlet connections:
VSF130 1” 1/2 – F
VSF130/2 2” – F by flanges screwed to the body.
Flange connections EN or ASME available on request.
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 decrease under the set point.
