Pneumatic Actuators

Asahi/America’s Series 79P pneumatic actuators for quarter turn ball and butterfly valves provide accurate and dependable control, especially in corrosive applications.

The units are compact, yet extremely durable and available in output torques from 59 to 40,710 in/lbs based on an 80psi air supply.

Three standard actuator materials are offered: glass-reinforced polyamide, cataphoresis & Rilsan-coated cast aluminum alloy, and 316 stainless stee – all of which incorporate ISO and NAMUR mounting configurations for simple installation of valves and accessories. These material choices provide excellent protection from adverse environments and corrosive process materials.

Two versions of this actuator are offered: single acting (air-to-spring or “failsafe”) and double acting (air-to-air). Both versions use a double piston, double rack and pinion design.
