Cadel Engineering Works supplies Double Lock Type Valves. Cadel Engineering Works manufactures valves like Single Lock Valves, Double Lock Valves, Release Assembly Valves, Ring Type Valves, etc. The Double Lock Type Valves are available in aluminum alloy, SS 304 and SS 316. A cylindrical, flexible diaphragm is fitted with flanges at both ends. The flange at the upper end is held stationary while the flange at the lower end is rotated so as to twist the diaphragm. These results in an effective locking and unlocking arrangement which helps control the flow of material through the diaphragm. In addition to the two flanges, an intermediate flange is introduced in the middle of the tubular diaphragm. The "middle" or "intermediate" flange is rotated while the other two flanges remain stationary. Since the middle flange rotates through 180 degrees, there is double locking of the diaphragm. An added advantage of this type of valve is that the bottom flange being "fixed" or stationary, the valve can be easily used with down-line equipment. An optional feature of Double Lock Type Valves is a guide sleeve passing through the orifice of the diaphragm. The sleeve will carry the material [e.G. Powders, granules etc.] without direct contact with the diaphragm. This feature helps to enhance the life of the diaphragm.
