Pinch Valve
|
Pinch Valves, ideally suited for the handling of slurries,
liquids with large amounts of suspended solids, and systems
that convey solids pneumatically, are relatively inexpensive
and the simplest in design of any valves. The effective
throttling range of a pinch valve is between 10 % and 95 % of
the rated flow capacity.
Fine Tech Pinch Valves are available in ‘sleeve exposed’ and
‘sleeve enclosed’ versions. In ‘sleeve exposed’ pinch valves
vacuum application is limited due to the tendency of the
sleeve to collapse when vacuum is applied. Flow control in the
‘sleeve enclosed’ version is by wheel & screw pinching device,
or hydraulically or pneumatically with the pressure of liquid
or gas within the metal case forcing the sleeve walls together
to cut off flow. |

As the closing mechanism in Fine Tech Pinch Valves is totally
isolated from the pipeline fluid, the valves gives minimum
pressure drop and hence, unobstructed full bore flow. The sleeve,
of a reinforced elastomer like neoprene, nitrile, hypalon, silicon
etc., is easily replaceable. In case of the requirement being very
specific, a suitable pinch valve to handle that specific need can
be designed and manufactured.
