General
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 controller.
- Response time is very fast and accurate.
- Split range 4~20mA or 12~20mA can be set by simple operating.
- Low air consumption.
- Simple Direct / Reverse Action change.
- Simple Zero & Span adjustment.
- Internal & External options,such as position transmitter (PTM) and / or limit switch(L/S)
are available. (Internal options are for non-explosion proof and External options are for
explosion proof.)
- 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 manually operate the
positioner or valve without any signal.
- It has IP66,Type 4X (FM) ingress protection grade.
- Epoxy polyester power coating resists the corrosion process. (except YT-1000)
- Maintenance of the positioner is easy because of modularized inner structure.
