➢The manual can be altered or revised without any prior notice. Any changes in product’s
specification, design, and/or any components may not be printed immediately but until the
following revision of the manual.
➢When the manual refers to “Valve Zero / Zero” means the final valve position upon pneumatic
pressure has been fully exhausted from positioner’s OUT1 port. For example, the valve zero
position may differ between linear direct and reverse actions. (DA/RA)
➢The manual should not be duplicated or reproduced for any purpose without prior approval from
Rotork YTC Limited, Gimpo-si, South Korea.
➢In case of any other problems that are not stated in this manual, please make immediate contact
to Rotork YTC Limited.
➢Positioner is an accessory of the control valve, so please make sure to read the applicable
instruction manual of the control valve prior to installation and operation.

1.3 Explosion Proof Warning (Only for explosion proof type positioners)
Please ensure the unit is being used and installed in conformity with local, regional, and national
explosion proof environment.
➢Refer to “2.6 Certifications”
➢Explosion proof type of cables and gaskets should be used, when explosion gases are present at
the installation site.
➢Power should be turned off completely when opening product’s cover. When opening the cover,
ensure that there is no power remaining in any electrical parts nearby.
➢Flameproof enclosure type positioner has 2 ports for power connection. Explosion proof type wires
and packing should be used. Blind plug is required when any port is not being used.
➢Ring terminal with surface area of more than 1.25 mm2 with M4 spring washer should be used to
connect the power.
➢For external ground terminal, ring terminal with surface area of more than 5.5 mm2 should be used.
➢There is risk of explosion due to static electricity charge. Static electricity charge may develop
when cleaning the product with a dry cloth. It is imperative to avoid static electricity charge in the
hazardous environment. If cleaning the surface of the product is needed, must use wet clothes.
➢To meet explosion-proof marking information and ingress protection of IP66, use certified Ex-cable
glands and Ex-plugs.
➢If you need additional information about the values of the flameproof joints, contact Rotork YTC
Limited directly.

2 Product Description
2.1 General
YT-1000 / 1050 series Electro-Pneumatic Positioner accurately controls valve stroke in response to an
input signal of 4 ~ 20 mA from the controller.
2.2 Main Features and Functions
➢It is compatible with most of controllers.
➢Response time is very fast and accurate.
➢Split range 4 ~ 12 mA or 12 ~ 20 mA can be set by simple operating. (Inform us when ordering as
the parts are different.)
➢Low air consumption.
➢Simple Direct / Reverse Action change.
➢Simple Zero & Span adjustment.
➢Position transmitter or limit switch is available as internal or external option on the positioner.
However, positioner is non-explosion type when internal option has been selected. In case of
external option, both the positioner and the external products can be selected with explosion-proof
certified products.
➢Orifices can be installed even in the field to minimize the hunting occurrence and optimize
operating conditions.
➢A/M switch can be used to direct supply air to the actuator or to manually operate the positioner
or valve without any signal.
➢It has IP66, Type 4X (FM) ingress protection grade.
➢Polyester powder coating resists the corrosion process. (except YT-1050).
➢Maintenance of the positioner is easy because of modularized inner structure.
