2. Air Supply Pressure:
Standard double-acting actuators require 40-120 psig supply
air. Spring-return actuators require 80-120 psig supply air.
Spring-return actuators can also be set up to operate on
supply air pressures ranging from 40-80 psig by using fewer
springs. See “Rebuilding Instructions”, Spring-Return
Actuator, paragraph 1 on page 12 for proper number and
location of springs for reduced supply air pressures.
3. Air Supply Connection:
Connect air supply to Z\v" NPT connection on control block.
For units with no integral solenoid valve, air connection block
has two
Z\v" NPT connections for inlet air (only one used for
spring-return units).
4. Recommended Tubing Sizes:
In order to provide sufficient flow of supply air to the Series
39 actuator, the following tubing sizes are recommended:
5. Air Consumption:
The following chart shows the amount of pressurized (80
psig) air consumed per stroke in cubic feet. To determine the
total amount of air consumed per complete cycle for double-
acting actuators, simply add the volumes for both the
opening and closing strokes together; for spring-return units,
the total volume of air consumed is the volume shown for
the opening stroke.
6. Electrical Supply:
Make electrical connections in accordance with the wiring
diagram on the inside of cover or appropriate wiring diagram
in Section B.4.
The power supply to the solenoid coil is three watts. Required
amperage is as follows:
*Inrush is 80% greater than holding values on AC solenoids.
7. Switch (Sensor) Ratings:
Mechanical Switch – 15.1 amps at 125/250 VAC; 5 amps at
125 VDC.
Proximity Sensor – 5-200 mA, 20-140 VAC, 10-140 VDC,
current leakage < .8 mA, sensor frequency 25 Hz. Not
sensitive to polarity.
ELECTRICAL CONNECTION
NOTE: Wiring diagrams for units with a PC board as found in this
IOM are for the new PC board. The solenoid (power) and the limit
switch circuits of the new PC board are now separate. The new board
is rated for 10 amps maximum and can be identified by the board
part number label. See table on page 8 for identification of color-
coded part number label.
The old circuit board in the original unit was designed for a single
voltage and current for the solenoid (power) and limit switches, and
was rated for 6 amps maximum. If used on a dual voltage installation,
damage will occur in the control device.
B. 1. The “standard” mounting configuration of the 39 actuator to
the valve is in-line, fail-closed. In this configuration, SW-2, as
described in part 3 below and in the wiring diagram, will give
indication when the actuator is in the closed position, or CW
(clockwise) limit of rotation and the red LED will be on. SW-1
gives indication of the open position, or CCW (counter-
clockwise) limit of rotation and green LED will be on (refer to
appropriate wiring diagram in Section B.4.).
NOTE: The CW or CCW rotation of the actuator shaft is
determined when viewing the actuator from the nameplate
side of the actuator while being able to read the nameplate
from left to right.
2. Fail-open mounting configuration may be obtained by either
inverting the actuator, using in-line coupling or mounting the
actuator cross-line. In these cases, SW-1 and SW-2 indication
will be reversed from the above but actuator shaft rotation will
vary depending on which fail-open mounting is used. The fail-
open wiring diagrams in Section B.4 and adjustments in
Section 3 below are for cross-line mountings only. For wiring
and adjustments of other fail-closed or fail-open
configurations consult Flowserve.
3. Switches (sensors) have been factory adjusted, but should be
rechecked after installation. Adjustment is as follows:
a. Switch adjustment for “standard” mounting (24 VDC; 24,
120 VAC PC Boards using LEDs):
With actuator mounted in “standard” mounting
configuration (see step 1) and wired per appropriate
wiring diagram, set actuator in the closed position. With
the adjustment screw near its loose limit, adjust closed
position switch SW-2 by tightening the adjustment screw
until red LED turns on. Then tighten the adjustment screw
one additional turn. With air supply to actuator, energize
the solenoid and cycle valve to full open position. The red
LED will shut off and the yellow and orange LEDs will be
lit indicating the valve is no longer in the fully closed
