Purchase Specifications
The valve shall open to allow filling of the tank and shall close
tightly when liquid level reaches predetermined high level. The
valve shall consist of a main valve and a remotely located float
control. The main valve shall be a hydraulically operated,
diaphragm actuated, globe 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
renewable seat. The valve stem shall be guided at both ends by a
bearing in the valve cover and an integral bearing in the valve seat.
The diaphragm assembly shall be the only moving part and
shall form a sealed chamber in the upper portion of the valve,
separating operating 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 and/or stuffing boxes are not permitted and
there shall be no pistons operating the valve. All necessary
repairs shall be possible without removing the valve from the
line. If the diaphragm becomes damaged the valve shall close
tight. Valve shall be equipped with a position indicator.
The pilot control shall be a precision-lapped, rotary-disc, plate
type valve. Positioning of the pilot valve shall be by a float and
arm assembly.
This valve shall be the Model 129AF-1 High Level Shut-Off
Valve as manufactured by Cla-Val, Newport Beach, California.
