Pressure Reducing Valve – PR Valve

Pressure Reducing Valve – PR Valve piston EOLO PN 20 – 1/2” – PR Valve

The EOLO model pressure reducing valve is an automatic valve that reduces and stabilizes the pressure of a fluid in a water distribution conduit according to a preset value.

Its reduced size, silent operation and internal self-cleaning seat render this valve ideal for use in espresso machines. The nickel-plated surface, besides giving it a pleasing appearance, protects against corrosion and calcareous incrustation. Given the valve’s elevated maximum allowable working pressure, it may be connected directly to main distribution networks, where the water pressure reaches values up to 20 bar.

The internal piston structure guarantees rigidity, strength and an enhanced regulation precision thanks to the compensated seat. The O-rings, in anti stick-slip Perox EPDM elastomer with a low friction coefficient, are durable and require only limited maintenance interventions. The internal finish of the body and the broader dimensions of the passage allow an elevated flow even with a small water draw. This product adheres to the standards set forth by the European health authorities for the transport of alimentary fluids and
potable water.
