Purchase Specifications
The Model 100S/2100S shall be a hydraulically operated, diaphragm-actuated, globe or
angle pattern valve. It shall contain a resilient, synthetic rubber disc, having a rectangular
cross-section, contained on three and one-half sides by a disc retainer and disc guide,
forming a tight seal against a single removable seat insert. The diaphragm assembly, con-
taining a valve stem, shall be fully guided at both ends by a bearing in the valve cover and
an integral bearing in the valve seat. This diaphragm assembly shall be the only moving
part and shall form a sealed chamber in the upper portion of the valve, separating operat-
ing pressure from line pressure. The diaphragm shall consist of nylon fabric bonded with
synthetic rubber and shall not be used as a seating surface. Packing glands or stuffing
boxes are not permitted and there shall be no pistons operating the valve or its pilot con-
trols. All necessary repairs shall be possible without removing the valve from the line. All
materials shall be compatible with seawater.
Valve shall be Model 100S/2100S manufactured by Cla-Val, Newport Beach, CA 92659-0325
