GENERAL INFORMATION

The following instructions are designed to assist with

installing, calibrating and troubleshooting the Valtek

Position Pac™ valve position indicator. Product users

and maintenance personnel should thoroughly review

this bulletin in conjunction with the maintenance bulletin

for the appropriate valve body and actuator being used.

To avoid possible injury to personnel or damage

to valve parts, WARNING and CAUTION notes

must be strictly adhered to. Modifying this prod-

uct, substituting non-factory or inferior parts, or

using maintenance procedures other than out-

lined could drastically affect performance, be

hazardous to personnel and equipment, and may

void existing warranties.

OPERATION

Position Pac is a ‘package’ unit containing a potenti-

ometer and transmitter, two or four limit switches, or a

combination of a transmitter and two limit switches.

The position transmitter utilizes a potentiometer to

measure the valve’s position and a transmitter circuit

that sends a 4 to 20 mA electrical signal to a remote

monitoring device. Position Pac will continuously trans-

mit the position of a control valve as it modulates

between the open and closed positions.

The limit switches in Position Pac can be independently

set to indicate open, closed or any intermediate valve

position.

Valtek Position Pac

Position Pac’s sealed construction provides protection

from the entry of water, dust and oil as defined by the

National Electrical Manufacturers Association (NEMA)

1, 3, 3R, 4, 12 and 13. Position Pac is also explosion-

proof, providing protection from flammable hydrocarbon

atmospheres, metal dust, coal dust, and grain dust. It is

UL and CSA listed for Class I, Division 1, Groups B, C, D;

Class II, Division 1, Groups E, F, G (See Table I). All

electrical wiring should be installed per NEC articles

501-4 and 501-5.

WARNING: Keep hands, hair, clothing, etc. away

from moving parts when operating the valve. Fail-

ure to do so can cause serious injury.

INSTALLATION INSTRUCTIONS

The following instructions are designed to assist in the

field installation of Position Pac units.

Valtek Linear Actuators

To install Position Pac on Valtek linear actuators, refer

to Figures 1 and 2, and proceed as follows:

1. Remove the name plate from the yoke leg opposite

from the stroke indicator plate.

2. Using the two tapped holes, attach the Position Pac

mounting bracket to the yoke leg using two mounting

bolts. When facing this yoke leg, the bracket will jog

in towards the valve center and protrude to the left.

3. Remove the nut from the stem clamp bolting. Place

the tripper bracket on the bolt so the ‘S’ shape ex-

tends down. Replace the nut and tighten it firmly.
