OPERATION

The Cla-Val Series PV20 Closed Body Pinch Valves provide simple means to
manually control the flow of abrasive and corrosive slurries, liquids and solids.
The valve operates by turning the handwheel clockwise to close, counter­clockwise to open like a gate valve, but unlike a gate valve the PV20 series
valve has no packing or metal surfaces to wear out - the sleeve is merely
squeezed to the desired open or closed position.The standard sleeve materi­al, pure gum rubber, is made with reinforced polyester fabric for highest
strength and longer lasting cycle life. Sizes 8” and larger are available with
bevel gear operators for automatic operation.

MAINTENANCE

Cla-Val Pinch Valves are basically maintenance free because the sleeve iso­lates all mechanical parts from the media. The sleeve is the only part typical­ly inventoried for future replacement.

Heavy Construction at No Extra Cost!
