- Infinite intermediate positions are possible with the limit switch
- It can be fine tuned to the application easily
- The settings can be changed at site with ease, by simply adjusting the third cam provided
- It is applicable for 90 or 180
- Any spring return actuator can be converted into this arrangement by adding Metso limit switch along with NAMUR valve type 30138
- The accuracy and repeatability depends upon the air pressure variation, change in the torque of ball valve, change in density and the pressure of media, etc

QTF actuator for regulating service
Features
- Backlash free operation between rack and pinion makes the actuator suitable for regulation duty coupled along with positioner (pneumatic or electro-pneumatic)
- Long life of the actuator seals, the non-wearing characteristic of the mechanical parts ensure that the control action is maintained, over the life time of the actuator
- It can be coupled along with the various types of valves (ball, V-port ball or plug, segment ball, butterfly, plug) or louvers and dampers for variety of applications
- Typical control schemes along with the regulating actuator includes provisions for:
- 1. Air failure safety includes stay-put or fail safe operation, like full close or full open
- 2. Power failure safety, including stay-put or fail safe operation, like full close or full open
- 3. Both air & power failure safety, including above
- The single acting 180 actuator can provide centre off for the 3-way ball valve, bottom entry by choosing theoption, of 3-position
- It can be converted to 3-position 0 90 180 actuator for 3-way valves using Metso limit switch and NAMUR valve type 30138
- The end stop adjustment is provided for opening and closing direction as a standard
- Actuator mounting is as per ISO 5211 and accessories to NAMUR
- 180 actuator has 50% of torque value, of that of 90actuator
