Acro-Matic YT1000 Series Valve Positioner
For over fifteen years Acrodyne have been suppliers of the Acro-Matic YT1000 electro pneumatic positioners to the Australian market. The YT1000 can be supplied in either rotary or linear format. The rotary option suits all ¼ turn applications such as rack and pinion and scotch yoke actuators whilst the linear is easily adaptable to diaphragm control valves and linear pneumatic cylinders.
The enclosure consists of diecast aluminium with epoxy paint protection and has an IP66 ingress protection rating. The feedback shaft consists of 316 stainless steel which addresses any corrosion issues which may be encountered. An easy to see visual indicator is standard which indicates true valve position. The option of a rotary dome indicator greatly increases visual indication especially for hard to see locations.
Low air consumption to around 3 litres per minute is another feature of the YT1000 which greatly reduces operational costs. The YT1000 has the ability to be converted from direct acting to reverse acting and can also be set up as split range. Resistance to high vibration is another key feature offering reliable and trouble free performance.
Internally no special tools are required for span or zero calibration. The inclusion of a manual pneumatic override makes trouble shooting easy in the field. The YT1000 requires a 4-20mA loop signal and can be optioned with a 4-20mA feedback signal (Position Transmitter). In addition 2 electrical dry contacts can be added for open and closed indication (Limit Switches)
Acrodyne can supply a range of mounting kits to suit most rotary and linear actuators.
