Spring Packed Radiator Hand Actuated Valves

Sterlco Spring Packed Radiator Hand Actuated Valves Model 511 is designed for steam heating systems with pressures of 25″ of vacuum to 150 PSI. It may also be applied to water systems with pressures up to 200 PSI. Like other Sterlco® Radiator valves, the 511 is equipped with positive “on” and “off” control for any type of heating element or radiator. 511 Valve features a heavy brass body casting which will resist strains during installation. This simple, rugged pattern is available in four body patterns. Heavy coil spring maintains pressure on special one-piece synthetic fiber ring, providing a tight seal around the valve stem. Valve is fully opened or closed with less than one turn of the handle. Positive valve shut-off means a perfect seal in closed position. Attractive, simple styling, heat-resisting composition handle with non-rising stem, permits installation in exposed locations.
