10 minutes

Prerequisites

• Clean, dry, oil-free air supply

• 147-2000 Positioning Relay

• Part number of the valve assembly or the

stem travel of the valve

Installation

1. Attach the relay mounting bracket (1) to the

lower housing of the valve actuator with the

clamp (8) provided. The lower edge of the

bracket must be against the lower housing

extension.

2. Attach the relay to the mounting bracket with

two captive screws furnished on the relay body.

Loosen the cover screw to remove the cover for

access to one of the screws.

3. Attach the feedback arm to the lever assembly

on the relay using the two screws and two lock

washers provided with the relay. The feedback

arm must clear the mounting bracket and the

actuator lower housing.

4. Loosen the lower hex nut on the valve stem

with an open-end wrench and slip the spring

arm between the hex nuts.

5. Position the spring arm (7) on the valve stem so

the hole for the adjusting screw (3) is in line

with the spring guide. Lock in position between

the two hex nuts on the valve stem.
