YT-1000 / 1050 series Electro-Pneumatic Positioner accurately controls valve stroke in response to an input signal of 4~20mA from the controller
Main Features and Functions
➢ It is compatible with most of controllers.
➢ Response time is very fast and accurate.
➢ Split range 4~12mA or 12~20mA 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
