100-42 700 Series Roll Seal Valve

The Cla-Val Pacific 100-42 Roll Seal valve is a hydraulically operated valve used to control liquid flow by means of a flexible control element: the liner. 
The basic valve consists of only two parts: a one piece, investment cast body and an elastomeric liner. The valve body is constructed with internal ribs and slots forming a grillwork which surrounds the liner to provide support. A normally closed type valve is formed by the installed liner which covers the grillwork and seats against the raised seating surface in the valve body. 
This valve is tested and shown to be in compliance with NSF/ANSI  61 Drinking Water System Components - Health Effects Standard.  Please see Certifications & Approvals for more information.
