Main features

RTX1000 - Electro Pneumatic Positioner
  • Compact design, rugged construction with rigid ISO5211 mounting
  • Vibration resistant because of its unique design and construction
  • Quick and ultra-precise response of torque motor
  • Special polymer shaft bush with built in grease reservoir to avoid shaft seizure due to formation of aluminum oxide
  • Split range control can be easily adopted by change in few internal components
  • Simple to convert from direct acting to reverse acting or vice versa
  • The springs exhibit a stable force along with a highly balanced diaphragm
  • Low hysteresis due to lip seal instead of an O-ring which results in high gain and low friction
  • Various orifice size options available for different volume of actuator to prevent from hunting and also to control speed
  • Easy and precise calibration with zero and span adjustment
  • All the internal parts are anodized
  • Bright visual indicator on both flat and high dome type positioners
  • Internal and external mounting of the position transmitter and limit switch made possible and easy
  • No component is exposed thus preventing from corrosion in hazardous environment
  • IP66 protection
  • CE certified
RTX1200 - Pneumatic Positioner
  • Special polyethylene low pressure diaphragm direct acting valve ensures quick and precise response to minor changes in signal pressure
  • Zero hysteresis increases overall efficiency
  • Normal operation in extreme environmental conditions such as vibration
  • High life of diaphragm and zero maintenance
  • Compact design, rugged construction with as rigid ISO 5211 mounting
  • Wide range of zero and span adjustment for easy and precise calibration
  • Stable, fast and accurate response with change in supply pressure due to unique poppet and diaphragm valve design
  • All the internal parts are hard anodized
  • Split range control can be easily adopted by change in few internal parts
  • Simple to convert from direct acting to reverse acting or vice versa
  • Throughout there is a stable spring force along with a highly balanced diaphragm
  • Low hysteresis due to lip seal instead of an O-ring which results in high gain and low friction
  • Orifice option prevents from hunting and also controls speed
  • Bright visual indicator on both flat and high dome type positioners
  • Internal and external mounting of the position transmitter and limit switch made possible and easy
  • Internal circuit of the positioner is highly corrosion resistant as no part (metal plate) is exposed
  • IP66 protection
  • CE certified

ROTEX Infinity actuators are engineered to provide the longest possible service life. The exclusive ROTEX V-Seal polymer double lip seal offers the most efficient, dynamic sealing in the industry. Massive bearings with greater surface area allow for higher load capacity. Monolithic billet pinion provides for incredible strength and durability. Two-part epoxy paint over anodized aluminum body gives superior corrosion protection. Infinity actuators are greater than the sum of their parts.

ROTEX warranties the complete actuator for 3 years or 3 million cycles, including all seals. All major components, including body, pinion, bearings, springs, seals, and all hardware are covered for the full term of the warranty. No other actuator manufacturer stands behind their product the way ROTEX does.
