Series 01 Handle and Notch-Plate
Bray offers handle assemblies for standard Resilient Seated Valves from 1”-6” [25-152 mm] (Through
12” [305 mm] with undercut disc assemblies). These quarter turn handles have a locking spring and a
directional pointer for valve disc position indication. Bolted notch plates with on-off stops to prevent over
rotation of the valve disc complete the assembly.
WARNING: Do not use handle or notch plate to lift a valve assembly.
The following procedure is recommended when mounting a Series 01 handle and notch plate on a
resilient seated valve:
NOTE: For readjustment of the handle and notch plate assembly in the field, remove the
handle and notch plate from the valve and remount according to the procedures below.
!
Step 1: Mount the handle without the notch
plate and use it to assure that the “Double D”
flats on the valve stem are aligned parallel with
the face of the valve
(See Figure 1).
NOTE: When mounting the Series 01 handle
with the valve out of the line it is more ac-
curate to measure from the face of the valve
to the disc face at the 90° and 270° positions
using the handle to adjust the disc until the
measurements are equal
(See Figure 2).
Step 2: Once the Double D flats on the stem
and the disc are centered, remove the handle
and attached the notch plate to the mounting
pad on the valve with two (2) fasteners
(See
Figure 3). Do not tighten the bolts.
Step 3: Carefully replace the handle and make
sure the latch on the lever properly engages the
first notch
(See Figure 4).
Step 4: Tighten the notch plate fasteners.
