The Type-21 ball valve from Asahi-America has the ability to mount a series 79 pneumatic actuator to allow for the valve to be controlled via an air supply. Standard set ups are available in "ready to ship" packages that can be sent out in 24 hours. The actuators are sized to operate on 80 psi of air pressure, and can be sized to operate on different air pressures upon request. Actuators are available as either air to air (double acting) or air to spring (single acting), with fast pack air to spring units being set up as fail closed. The actuators are mounted on the valve through a coupling and bracket set up with an ISO bolt pattern. Units have a visual position indicator and operate as quarter turn actuators.
