CLA-VAL 129AF-1 : High Level Shut-off Valve
The Cla-Val Model 129AF-1 High Level Shut-Off Valve automatically opens to fill a storage tank and closes tightly when liquid level reaches a predeterminded point. No attention is required once adjusted to the desired level. It is a hydraulically-operated, diaphragm-actuated, pilot-controlled globe pattern valve. Should the diaphragm become damaged the valve will close tight, provinding "fail safe" operation. The 129AF-1 is controlled by a CFM2 float actuated pilot mounted near the hugh level shut-off point in the tank. The float pilot control is a precision-lapped plate type valve actuated by a float attached to a lever arm.
