Metal, PVC, & Lined Diaphragm Valves, Actuators & Controls

Century Diaphragm Control Valves are ruggedly designed to give the maximum in performance, and will provide the essential flow characteristics required wherever highly accurate control of temperature, pressure, or flow is desired, in the handling of steam, water, air, oil, or gas.

They are widely used, in conjunction with pilot liquid level controls, and air-operated temperature and pressure controllers, on all types of industrial applications, such as chemical processing, oil refining, plating, metal furnishing, rubber vulcanizing, etc.

For automatic and remote control of difficult - hard to handle and corrosive services, Century close-coupled actuators on Saunders Type diaphragm valves offer positive, low cost, trouble free operation. Because the valve body can be lined with glass, rubber or plastic, it can be produced less expensively than the exotic metals normally required of corrosive materials.

Rugged, close-coupled Century actuators are available in all three modes: spring to open, spring to close and springless air to air.

Advantages of Century Automatic Diaphragm Valves

• 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 vertical, horizontal, or any intermediate position.
