CONVENTIONAL DIAPHRAGM ACTUATORS• Effective Area variesthroughout the Travel• Diaphragm Pivots Acrossthe Edge of the DiaphragmPlate• Thick Piston Plat Requiredfor Support of Diaphragm• Single/Double ConcentricSprings or Multiple OffCenter Spring Designs• Little/No Friction withCycling Except for ShaftSeal and Bearing Loads• Travel is Limited

REASONS FOR USING CONVENTIONAL FLATDIAPHRAGM ACTUATORPros• Most Economical• Reliable• Long History of Field Performance• Low Cost of OwnershipCons• Diaphragm Area Not Constant• Limited on Travel Lengths• Limited on Air Supply Pressure• Requires a Lot of Space• To Field Reverse, Requires New Actuator

REASONS FOR USING MULTI-SPRINGDIAPHRAGM ACTUATORPros• Lower Cost of Ownership• More Economical• Reliable• Long History of Field Performance• Constant Diaphragm Area• Less Space Required• Field Reversible without added parts• WeightCons• Limited Travel• Limit Air Supply

Multi Spring ActuatorDirectReverse

87/88 FEATURES• Multiple Spring DesignFour standard spring types achievable byvarying spring quantity and placement• Heavy One-Piece YokeProvides maximum strength and rigidity.• Diaphragm CasesPressed steel upper and lower casescombine lightness, high mechanical strengthand protection in the event of overpressurization.

WHY DO YOU WANT TO USE CYLINDER?• Handles High Air Supply Up to 100 PSIG Versus 60PSI• Longer Strokes• Increase Force Output Even More by RemovingSpring• Faster Response• Larger Sizes Require Less Space• More Economical Than EHA and Electric
