YT-3700 / 3750 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, and HART Protocol Communications.
Main Features
◆ LCD display enables users to monitor the positioner status.
◆ User will easily understand the method of using 4 buttons because it work same in all versions of firmware interfaces.
◆ When unexpected situation like momentary blackout happens, our positioner boot-time only take 0.5 second and this can minimize the travel of valve which consequentially increase the safety of system.
◆ Positioner operates normally even there are sudden changes in supply pressure and / or high vibration environment.
◆ The method of Auto Calibration is very simple.
◆ As an advantage of having very low air consumption, It could greatly reduce operating costs in large-scale plants.
◆ It is compatible with most of controllers.
◆ Orifices can be installed even in the field to minimize the hunting occurrence and optimize operating conditions.
