Positioners
Our electro-pneumatic positioners and pneumatic positioners are designed for the operation of quarter-turn or linear actuated valves in accordance with a proportional control signal. The design utilises a robust aluminium enclosure and stainless steel components for long-term reliability in harsh operating environments.
Excellent operating performance delivers repeatability of less than 0.3% of full range, hysteresis of less than 0.5% of full range and 99% full range linearity. All models are available with ATEX certification for operation in hazardous areas.
The Electro-Pneumatic Positioner YT-1000R is used for operation of pneumatic rotary valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20mA or split ranges.
- Simple zero and span adjustment
- No resonance between 5-200Hz
- Auto/Manual switch
- RA v.s. DA action and 1/2 split range setting by simple adjustment.
- Internal feedback signal is available as an option (weather proof only)
The Pneumatic Positioner YT-1200R is used for pneumatic rotary valve actuators by means of pneumatic controller or control systems with an output signal of 3 to 15 psi or split ranges.
- Simple zero and span adjustment
- No resonance between 5~200Hz
- Auto/Manual switch
- RA v.s. DA action and 1/2 split range setting by simple adjustment
