Product Description

YT-2300 Smart Valve Positioner accurately controls valve stroke, according to input signal of 4-20mA,

which is being input from the controller. In addition, built-in micro-processing operator optimizes the

positioner's performance and provides unique functions such as Auto calibration, PID control, Alarm,

and Hart protocol.

YT-2300R YT-2300L

Main Features and Functions

1. LCD display enables users to monitor the status of the positioner.

2. The positioner operates normally even if there are sudden changes in supply pressure and in

high vibration environment.

3. The method of Auto Calibration is very simple.

4. Due to the small size of the positioner, it can be installed on a small actuator.

5. Low air consumption level and low voltage use (8.5V) yield to lower operating cost. The

positioner is compatible with most of controllers.

6. Variable orifice can minimize the hunting occurrence and optimize operating condition.

7. Various sets of information can be interchanged by HART communication protocol between a

valve and a positioner.

8. Valve system becomes more stable by outputting analog feedback signal.

9. Various characteristics of valve can be adjusted - Linear, Quick open, and Equal percentage.

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

11. PID parameters can be adjusted in the field without any additional communicator.12. A/M Switch can change the flow of the pressure, whether to send directly to actuator or to

operate by positioner.

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

14. Hand Calibration function can set Zero and Span values.

15. It has IP66 protection grade.

16. Air filter regulator can be attached with only one linear nipple. It does not require extra piping.

17. Epoxy polyester powder coating resists against the corrosion process.

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

Installation

Safety Warning

When installing a positioner, please ensure to read and follow safety instruction.

All input and supply pressure to valve, actuator, and other related devices must be

turned off.

Use bypass valve or other equipment to avoid entire system "shut down."

Make sure there is no remaining pressure in the actuator.

Tools for Installation

Hexagonal wrench

Screw drivers (+) & (-)

Spanners for hexagonal-head bolts

YT-2300L Installation

YT-2300L should be installed on linear motion valve such as globe valve or gate valve using spring

return type of diaphragm or piston actuator. Before installation, be sure to check for following

installation components.

YT-2300 main body

Feedback lever and lever spring

Flange nut (bottom side of YT-2300L)

4 pcs of hexagon head bolts (M8 x 1.25P)

4 pcs of M8 plate washer

(1) Proper bracket must be made in order to attach positioner on the actuator yoke. Please

consider following when making a bracket.

Feedback lever should be leveled at 50% of valve stroke. (Refer to Step 7)

Feedback lever connection bar of actuator clamp should be installed at the positioner that the

valve stroke and numbers which indicated on the feedback lever must be fitted. (Refer to Step

8)

(2) Attach YT-2300L to the bracket, which was made in earlier step, by using bolts. Please refer to backside of the product for size of the bolts. The standard size of bolt is M8

X 1.25P, and other bolt sizes are available. Please contact YTC sales department.

(3) Attach YT-2300L (with bracket) to the actuator yoke - DO NOT TIGHTEN COMPLETELY.

(4) Connect YT-2300L feedback lever to the actuator clamp. The gap on the YT-2300L feedback

lever is 6.5mm. The connection bar thickness should be less than 6.3mm.

(5) Connect air filter regulator to the actuator temporarily. Set supply pressure of the regulator in

order to position the actuator clamp at 50% of valve stroke.

(6) Insert connection bar into the YT-2300L feedback lever. The connection bar should be

inserted at the 50% point on the feedback lever, which would help to reduce

hysteresis.

(7) If connection bar does not point at 50% point, then adjust bracket or feedback link bar position.

Failure to position at 50% would lower the linearity of the positioned

(8) Check valve stroke. The stroke numbers are indicated on the feedback lever. Position

connection bar at the number on the feedback lever according to the valve stroke. To adjust, move the bracket or the connection bar.

Note

After installing YT-2300L, operate the valve from 0% to 100% stroke by using air filter

regulator on the actuator. Both at 0% and 100%, the feedback lever should not touch the

lever stopper, which is located on the backside of YT-2300L. If the feedback

lever touches the lever stopper, YT-2300L should be installed further away from the center of

the yoke.

(9) After the proper installation, tighten all of the bolts on the bracket, the feedback lever, and the

connection bar.

YT-2300R Installation

YT-2300R should be used for rotary motion valve, that is ball valve, butterfly valve using rack and

pinion, scotch yoke or complex type actuator, which its stem rotates 90 degrees. Before installation,

be sure to check for following installation components.

YT-2300R main body

Fork lever and lever spring

1 set of bracket

4 pcs of hexagon head bolts (M8 x 1.25P)

4 pcs of M8 plate washer
