Asahi America Inc. has expanded their pneumatic actuator product line by adding the M79P to their family of pneumatic actuators. The double acting (air to air) M79PN pneumatic actuator can produce up to 40,441in pounds of output torque based on an 80psi air supply. The single acting (air to spring) M79PSN pneumatic actuator can produce up to 15,660in pounds of output torque based on an 80psi air supply. This new unit incorporates standard features including adjustable travel stops, captive springs (single acting model only), aluminum alloy body and end caps with Cataphoresis and Rilsan coating inside and outside for maximum corrosion resistance, Cataphoresis coated steel output shaft with double o-ring seal on top and bottom, aluminum alloy pistons, nylon piston guide, PTFE and bronze piston guide rings, self-lubricating BUNA-N O-Rings and stainless steel external hardware. The M79P operates at a temperature range of -25F to 195F, provides output torque range from 15,660in/lbs to 40,441in/lbs at 80psi and is powered with air, non-combustible gas, or non-aggressive fluid. These new actuators are able to be mounted on Asahi/America large size butterfly valves (14in or larger) as well as most thermoplastic or metal large size ball valves and butterfly valves with standard ISO or NAMUR mounting dimensions.
