—Electro-pneumatic Valve Positioner Description—

• 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.
• 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 to manually operate the positioner or valve without any signal.
• It has IP66, Type 4X (FM) ingress protection grade.
• Epoxy polyester powder coating resists the corrosion process. (except YT-1050).
• Maintenance of the positioner is easy because of modularized inner structure.
