Chemline - Model AV Series - Manual Diaphragm Valves - Datasheet

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.
