ITT Engineered Valves Double Diaphragm Valve .5-F-428-6-TM-963 – ½” Flanged Dual-Body Manual Valve Assembly, Corrosion-Resistant, Ideal for Clean/Containment Service

Condition: Good used condition.
The ITT .5-F-428-6-TM-963 Double Valve Assembly is a dual-body diaphragm valve setup designed for redundant shutoff, containment isolation, or sampling loops in controlled process environments. This specific configuration includes two ½” ITT Dia-Flo diaphragm valves (Model 428 Series) joined in series or parallel, depending on intended flow control layout. It is typically used where zero leakage, high purity, or double block and bleed (DBB) functions are required.
This model is part of ITT’s robust Dia-Flo® diaphragm valve product line, known for top-entry access, maintenance-friendly design, and excellent corrosion resistance. The 428 Series is often used in chemical processing, pharma, and ultra-pure water systems, and the TM-963 suffix indicates a specific internal trim or diaphragm material configuration—possibly PTFE, EPDM, or a combination suited for chemical resistance or hygienic service.
