Max-Air SHD Series scotch yoke actuators sit perched atop beastly 8” Class 300 trunnion ball valves. Strong and swift, these spring return actuators tame the intimidating ball valves and force the ball to the closed position when critical shutoff is required. Complete with seamless mounting adaptation and outfitted with Max-Air limit switch feedback and solenoid valve, these actuators are hungry for torque and ready to automate your largest valves.
