Summary of D671X Pneumatic Butterfly Valves

 

     An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. Actuators are operated by some kind of power source, be it a human operator turning a valve handle, a pneumatic cylinder, or an electric motor. The two most common types of automatic actuators in the process industry are electric and pneumatic actuators.

     Pneumatic actuators are the most common type of automatic valve actuator we specify. A pneumatic actuator usually consists of a piston, a cylinder, and valves or ports. The piston is sealed to the cylinder wall with an o ring or some other type of elastomeric seal. Some pneumatic actuators use a diaphragm instead of a piston. The diaphragm keeps the air in the upper portion of the chamber, allowing air pressure to force the diaphragm/piston downward, moving the actuator stem, and actuating the valve.

      Most pneumatic actuators will utilize an air supply pressure of 40-120 PSI, with most common pressure ranges in the 60-80 PSI range. Higher air pressures can be difficult to guarantee and sustain, while lower pressure will require a very large piston in order to generate the torque needed to actuate the valve.

       Pneumatic actuators will often incorporate an additional spring for fail-safe operation. In a fail-safe actuator, when the air supply is lost, the spring drives the valve back to a predetermined location- either opened or closed. This is where the nomenclature for pneumatic actuators comes from.
