4" Flanged 3DS-4B Cast Iron Triple Duty Valve

A combination shut-off, center-guided non-slam check valve and calibrated balance valve in one device. The combination of three valves in one minimizes cost and reduces installation time. Available in angle or straight pattern in 1'' through 16'' sizes; in flanged, grooved or NPT connections. The Triple Duty Valve has a cast iron body, brass seat, cast bronze disc and SS stem. A calibrated nameplate and memory button allow return of the valve to the balanced position after shut-off. The backseating valve stem allows repacking under full-line pressure.
