    AV Manual Diaphragm Valves

    Chemline Type 14(1/2” to 4”) and Type 15(5” and 6”) Diaphragm Valves are an improved version of the older DV Series. The 8” and 10” DV’s are still current design but are now called Type 72. Types 14 and 15 have been redesigned using modern computer design technology. Improvements are higher pressure resistance, lower hand wheel torques to close, better hydraulics (lower pressure losses) and other features. Tests show Type 14 to outperform major competitors in resistance to bonnet leakage on tough applications with thermal cycling.

    Chemline Diaphragm Valves have service histories dating back to 1970 operating in some of the toughest chemical plant applications in Canada. They have proven internal and external corrosion resistance.

    This is an excellent throttling valve, and is suited for slurries or viscous liquids. Because of the self-draining design with no dead volume, it is good for sanitary and high purity applications. These diaphragm valves offers higher temperature/pressure ratings and chemical resistance compared to other Chemline valve types.

    ✓ Excellent Chemical Resistance
    Large Selection of materials including PVDF bodies and PTFE diaphragms for extremely aggressive services
    ✓ Externally Corrosion Resistant
    Plastic bonnet, handwheel, covered and sealed indicator
    ✓ High Pressure Resistance
    Designed with a high safety factor against leakage
    ✓ Designed for Long Diaphragm Life
    Standard travel stop prevents over-tightening and excessive stress on diaphragm
