S51 – VSF123 – VSF123/34
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 1” – F and 3/4” – F.
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 for pressure up to 15 bar (217, 5 psi), by a piston for greater pressure.
The product complies with the directive 2014/68/EU PED.
