Rotary actuators, valves

Airmax Pneumatics offers ISO rotary actuators for valves and damper control, from Aira Valve Automation. These are characterized by the following features: Namur standard pinion top (an international standard) - pinion (shaft) top drilled and slotted for easy assembling of switches, positioners and other accessories; Namur pad for solenoid valve (an international standard) - air supply ports are covered with interface plate as per Namur standard to facilitate direct mounting of solenoid valve at actuator; ISO-5211/DIN - 3337 standard mounting for valve (an international standard) - double bottom drilling for actuator to valve assembling and centering, designed for strength and easy mounting or interchangeability; ISO-5211//DIN - 3337 standard pinion bottom (an international standard) - bottom of the pinion (shaft) as female key, double square hole for assembling on valves with square key stem and in line or turned 45( designed for strength and sure - fix with stem; Sliding skates - the innovation for replaceable sliding skates, between pistons (racks) and internal bore surface of the actuator, just to avoid metal contact, which enhances the actuator life; Pre-loaded spring cartridges - the introduction of pre-loaded spring cartridges, that remove the danger in the case of disassembly of spring return actuator, and that allows easy change of spring number present inside; and Compact design - Aria actuators are designed as compact and common for both double acting and single acting (spring return), which offers high torque values. Internal sliding surface is lapped and anodised to minimum friction and long life of actuator. External protection: corrosion strength to 500 hours in salted fog.
