Installation, Operation & Maintenance Manual
Model 53BTX Duplex Strainer, Sizes ¾” – 4”
INSTALLATION (
CONTINUED
)
Eaton recommends that basket well drain plugs be removed
and pressure equalizer valves with a drain valve be installed
(standard on 4” size) see Figure 1.
Figure 1
Eaton also recommends replacing each cover plug with a vent
valve and piping to a safe area. See Figure 2.
Figure 2
Pressure gauges near the strainer inlet and outlet are required
to determine differential pressure across the strainer and
cleaning frequency. Pressure gauges are essential for the safe
operation of the strainer.
CAUTION: To protect the operator during
draining and venting, the fluid must be piped
to a safe area. This requirement is for all fluids
and water with temperatures above 120° F.
The operator should wear appropriate protective equipment
(goggles, gloves, vests, clothing etc.) consistent with the
process fluid for strainer operation and servicing.
START UP
1. Open cover vent valves and cartridge vent. Close pressure
equalizer valves and drain valve. Rotate the handle 90º
clockwise, so that the handle is over the strainer inlet.
2. Slowly allow fluid to enter the strainer. First, slowly open
the downstream valve nearest to strainer outlet. Then
slowly open the upstream valve nearest to the strainer
inlet.
3. Close cover vent valves and cartridge vent when air is
expelled. Rotate the handle 90º counterclockwise over the
right side basket well. See Figure 3.
Figure 3
OPERATION
The strainer handle’s position indicates which basket well is in
operation. The handle in the 3 o’clock position over the cover
indicates the right basket operation. This prevents access to
the basket underneath the handle. See Figure 3. The handle in
the 9 o’clock position indicates the left basket operation Note:
Above references are with the strainer inlet in the 6 o’clock
position.
SWITCHING FLOW
Open both pressure equalizer valve to insure that both basket
wells are pressurized and rotate the strainer handle 180°
(traveling over the strainer inlet) until the handle is over the
opposite basket cover from where the handle started. Close
both pressure equalizer valves.
