  • NAMUR VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
  • The standard angle of rotation is 180°. Additional travel rotations of 120°, 135°, 150° are available. MA016 and larger sizes feature a travel stop with ± 10° adjustment in both open and close directions (International Patent).
  • The 'patent pending' bottom plate design, unique to Dixon Sanitary secures a captive pinion (anti-blowout system) and permits flexibility in mounting by retaining AISI 304 nuts (standard) or AISI 304 bolts (optional) In either dual ISO patterns, or to customer dimensions
  • All pinions are supplied with anti-blowout retention in both directions
  • The female pinion drive Is standard with a double square output drive and optional with a double-D drive, keyed drive and designs to meet your specific requirements
  • Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle applications
  • The pinion teeth are engaged for the full length and stroke of the piston. The pinion height allows manual override without disturbing the position Indication
  • Extruded aluminum body is internally machined and lapped to exact specifications. All internal and external surfaces are anodized for corrosion resistance
  • External open/closed indicator Is standard, available for all rotations
  • Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings
  • Epoxy coated special steel springs are pre-loaded with non-metallic materials. The stainless steel end cap fasteners are extra long to allow for spring relaxation, all parts are corrosion resistant
  • Air pressure operation from 40 to 150 PSI. Water, nitrogen and compatible hydraulic fluids may as be used to power the actuator
  • All external fasteners are corrosion resistant stainless steel
  • All units are permanently lubricated at the factory with non-silicone grease
  • All units are externally stamped with a progressive traceable serial number
  • 100% of all units are factory pressure and leak tested
