Zeron Fastners
Industrial Valves & FastenersControl Valves
Control Valves are automated mechanical devices designed to modulate fluid flow, pressure, temperature, and liquid levels across industrial process systems by varying the size of the flow passage in response to signals from an external controller. At Zeron Fastners, we manufacture and supply a comprehensive lineup of high-precision Control Valves engineered to deliver optimal flow dynamics, tight shutoff, and ultra-reliable throttling performance even under severe service conditions.
Our Control Valves are available in linear globe, rotary eccentric plug, high-performance butterfly, and V-notch configurations, equipped with pneumatic diaphragm, piston, or motorized electric actuators. Built using top-tier materials including Carbon Steel (WCB), Stainless Steel (CF8/CF8M), Duplex, Super Duplex, Inconel, Monel, and Hastelloy, our control valves resist severe cavitation, flashing, and corrosive erosion across power plants, oil & gas refineries, petrochemical complexes, and pharmaceutical facilities.
