Series 22 Dia-Cam Pinch Valve
1/2″ to 3″ Sizes, Manual or Motorized Actuation, Quarter Turn
The Series-22 Quarter-Turn Dia-Cam valve is a high flow capacity pinch valve, designed for hard-to handle fluids, especially slurries. The valve interior consists of a fabric reinforced elastomeric or PTFE-lined Diaphragm Spool… the only wetted component of the valve. Two opposing gear-driven cams, contained in a flanged split vinylester-fiberglass body, act on the Diaphragm Spool, providing flow control over the entire 90 degrees of valve stem travel. The valve exhibits negligible pressure drop in the open position and bubble-tight closure even around solids in the closed position. Where solids in the slurry make operation of other types of valves such as ball, plug and butterfly valves extremely problematic, the Series-22 Dia-Cam valve is ideally suited for slurries since there are no “dead zones” in the valve internals.
