Carefully check and confirm actuator position when in confined areas, especially with non-symmetrical units likes Bettis. Specify torque requirements and safety factors for break away torque, especially for important safety valves, which are used only in emergency cases. Use partial stroke test procedures.
~Mick V., Engineer, Hoogvliet, The Netherlands
Consider maximum torque developed by actuator at full line pressure and select suitable valve stem torque. When air is available at 5 bar, use maximum air pressure to actuator rather than limiting to 3.5 bar, which is not economical.
~Vinayak Chillal, Marketing/Sales, Hubli, INDIA
Use a regulator on a smaller tank at a very high psi (thousands of PSI) to save space and money, and to achieve a constant actuation pressure (hundreds of PSI) for a greater number of cycles.
~Aidan C, Student, Cabin John, MD
Do not demand cheapest price- RELIABILITY is best assured by careful and conservative matching of an actuator to valve and process conditions, not by the cheapest assembly possible.
~Mike M, General Management, Osborne Park, Australia
Make sure that the actuator that you select has sufficient torque output to open and close the valve you are going to mount it on.
~Robert D., General Management, Hackensack, NJ
Go for the Pneumatic Valve Actuator more reliable and accurate in the equal % application.

Do check size when selecting for ESD.

Look for ultimate solution.
