Zeron Fastners
Industrial Valves & FastenersPressure Reducing Valves
Pressure Reducing Valves (PRVs) are self-acting control valves engineered to automatically reduce high, variable upstream pressure to a steady, predetermined downstream pressure regardless of fluctuations in inlet pressure or system flow demand. Zeron Fastners supplies top-tier Pressure Reducing Valves widely employed across steam distribution networks, commercial plumbing, fire water rings, and industrial air mains.
Manufactured in both direct-acting diaphragm designs for quick reaction on low-flow systems and pilot-operated piston designs for heavy-duty steam and water distribution mains. Built from Cast Steel, Ductile Iron, and Stainless Steel, our pressure regulators safeguard downstream equipment, lower energy consumption, and eliminate water hammer.
