- Select Air-To-Raise (Lower) actuator based on control (valve) action and fail-safe condition requirements.
- Select minimum actuator size based on stroke, pnematic control signal and maximum deliverable force requirements.
- Select spring based on stroke (T), pneumatic control range (typically, P1 = 3 PSI and P2 = 15 PSI), pre-load (typically, pressure drop x unbalanced area of plug ΔP x AP) and maximum allowable spring force (Fmax)

CAUTION: Use of an actuator supply gas other than air can create a hazardous environment because a small amount of gas continuously vents to atmosphere.
SUGGESTED SPECIFICATION
Pneumatic Actuator* shall be (Air-To-Lower) (Air-To-Raise) type with minimal internal volume for fast response and molded nylon reinforced BUNA-N diaphragm capable of delivering near constant force throughout (1") (1 1/2") minimum stroke. Actuator shall have a wide choice of interchangeable range springs with readily accessible compression nuts permitting easy range change and adjustment. Actuator shall include a position indicator to provide a visual aid in determining inner valve position. Pneumatic Actuator shall be W.E.
