Product Details

Korea brand YTC YT-3400 flameproof valve positioner

1. Product Description:

YT-3400/3450 series Smart Valve Positioner accurately controls valve stroke in response to an input signal of 4-20mA from the controller. Built-in micro-processor optimizes the positioner’s performance and provides unique functions such as Auto-Calibration, PID Control, Alarms, and HART Protocol Communications.

2. Main Features and Functions:

LCD display enables users to monitor the positioner status

Variable orifice can be used to minimize the hunting occurrence and optimize operating conditions.

Valve system feedback is greatly improved by the accuracy and fast response of the YT- 3400/3450.

Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and Custom which user can make 16 points characterizations.

Tight Shut – Close and Shut - Open can be set.

PID parameters can be adjusted in the field without any additional communicator.

A/M switch can be used to direct supply air to the actuator or to manually operate the positioner or valve.

Split range 4-12mA or 12-20mA can be set.
