Century Instrument Co. - Flanged End Manual CPVC (Solid Plastic) Diaphragm Valves (Unlined)

Catalog

Compact Low Profile
With the specially designed flat-top bonnet, the Century actuator provides a strong, totally enclosed unit with extremely low over-all height.

Wide Selection
Actuators furnished in seven sizes to provide more efficient and economical use of available operating air pressures up to 200 psig.

Longer Strokes
Together with higher air pressure capability provides greater flexibility in valve/actuator selection. Example, the No. 0 (smallest actuator) has more than double the stroke of its nearest competitor.

Lower Air Consumption
Because of unique design, air consumption is extremely low - in most instances less than half that of competition.

Adjustability
In the spring-closed actuator, the adjusting screw provides a convenient means of obtaining valve closure when line pressures are higher than expected.

Adaptability
Suitable for either pneumatic or hydraulic operation, the unit can be mounted in vertical, horizontal, or any intermediate position.

Description	N/A Wide Selection — available in a wide variety of body materials, linings and end connections. By utilizing such highly resistant linings as Saran, Polypropylene, Kynar, Tefzel, Glass, Rubber, etc., virtually any chemical service within the pressure/temperature limits of the valve can be handled safely and economically. No Stem Leakage — since the diaphragm isolates the fluid stream there is no need for a packing gland — no atmospheric contamination, no leakage or waste, no expensive maintenance of stem, seats or stuffing box. Bubble-Tight Shut Off — results when the downward thrust of the stem and compressor assembly molds the flexible diaphragm against the weir. The diaphragm will accommodate itself to rust, scale, slurry, or fibrous material. Streamline Flow — with minimum pressure drop because of the absence of grooves, pockets or sharp changes in direction of flow. Cost Saving — simple in-line maintenance. In less time than it takes to remove and replace a conventional valve, a new body diaphragm can be installed. Thus providing essentially a brand new valve at a tiny faction of the cost of a new or repaired conventional valve — all without removing the valve body from the line. Flow Control — the automated diaphragm valve provides an excellent means of handling the changing flow requirements in most process installations. By the addition of a positioner to the actuator, even more precise control can be achieved, especially in the handling of slurries, or viscous and fibrous materials. Body Materials — available in cast iron, ductile iron, carbon steel, stainless steel, Alloy-20, aluminum and bronze
