SAS61 Series Electronic Valve Actuators

Item Number: 129-612, Rev. AA Page 1 of 3

Product Description

The SAS actuators require a 24 Vac or 24 Vdc, Class

2, supply and a 0 to 10 Vdc or 4 to 20 mA signal to

control Powermite 599 Series terminal unit valves with

7/32-inch (5.5 mm) stroke. In the SAS61.33U, a

mechanical spring returns the valve to its normal

position when there is no power supply.

Warning/Caution Notations

WARNING:

Personal injury/loss of life may

occur if you do not perform a

procedure as specified.

CAUTION:

Equipment damage, or loss of

data may occur if you do not

follow the procedures as

specified.

Product Numbers

actuator

SAS61.33U – Spring Return (Fail-safe) actuator

Required Tools

• #2 Phillips or flat-blade screwdriver

• Flat blade calibration screwdriver (3 mm) for

wiring connections

• Wire cutter/stripper

Estimated Installation Time

• 12 minutes for wiring a factory-installed

actuator.

• 30 minutes for field replacement of an

actuator.

Prerequisites

WARNING:

Disconnect the controller power before

replacing the actuator.

WARNING:

If mounting the actuator to a valve

already in line, either close the shut-off

valves in the piping (upstream first,

then downstream) or switch off the

pump to allow the differential pressure

in the valve to drop.

Mounting

Figure 1 shows acceptable actuator mounting positions

for water applications. The recommended mounting

position of the actuator for low pressure steam

applications is between 45° and horizontal.

Installation

If you are mounting an actuator on a new valve, begin

with the instructions, Mounting an Actuator to a Valve.

Remove Actuator from Valve

1. Remove actuator cover screws using either a

No. 2 Phillips or a No. 2 flat-blade screwdriver and

detach actuator cover.

2. Identify and disconnect wires.

3. Replace actuator cover. Use cover screws to
