Series 22 Dia-Cam Pinch Valve Features
|
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.
The valve ID mates to Schedule 40 piping systems and installs
without flange gaskets. The valve is utilized in either ON-OFF
or FLOW CONTROL applications.
