Linear Electro-Pneumatic Positioner YT-1000L

Parameters of Linear Electro-Pneumatic Positioner YT-1000L

It is designed for high durability and performance in high vibration environment.

Durability has proven after testing of 1 million times, at least.

Response time is very short and accurate.

Simple part change can set 1/2 Split Range.

It is economical due to less air-consumption.

Direct/Reverse action can be set easily.

Zero & Span adjustment process is simply.

Feedback Connection is easy.

Linear Electro-Pneumatic Positioner YT-1000L

Description

Linear Electro-Pneumatic Positioner

YT-1000L serial electro-pneumatic positioner accurately controls valve stroke in response to an input signal of 4-20ma form the controller

 

Positioner

Main Features

It is compatible with most 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.

The position transmitter or limit switch is available as an internal or external option on the positioner. However, the positioner is the non-explosion type when an internal option has been selected. In the case of an 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, Type4X(FM)ingress protection grade.

Epoxy polyester powder coating resists the corrosion process.

Maintenance of the positioner is easy because of the modularized inner structure.
