Electro-Pneumatic Positioner

YT-1000 / 1050 series

Product Manual

Ver. 1.30

4.3

Linear positioner Installation

Linear positioner should be installed on linear motion valves such as globe or gate type which uses

spring return type diaphragm or piston actuators.

Fig. 4-2: Installation example

Before proceeding with the installation, ensure following components are available.

➢

Positioner

➢

Feedback lever and lever spring

➢

M6 nut and spring washer (fastening feedback lever to a main shaft)

➢

Bracket, bolts and washers for positioner – not supplied with the positioner

➢

Connection bar – not supplied with the positioner

4.3.1

Preparing Bracket for the positioner

Proper bracket must be made in order to adapt the positioner on the actuator yoke.

Please consider following important points when a bracket is being designed.

➢

Positioner’s feedback lever must be vertical to the valve stem at 50 % of the valve stroke.

➢

The connection bar of the actuator clamp for the feedback lever should be installed in such a way

that the valve stroke length coincides with the corresponding figure in “mm” marked on the

feedback lever. Improper setting may cause poor linearity
