Disassembly/Assembly Instructions
Series 36H Resilient Seated Buttery Valves
Disassembly –
1. Remove the gear operator or power actuator from the actuator mounting ange.
2. Secure the valve in a horizontal position with the taper-pin nuts facing upward.
CAUTION
Prior to removal of the valve stem the valve disc must be secured and
supported to insure it does not drop out of the valve body once the stem is
removed. Lay the valve down with two wood blocks located under the disc
at the 6 o’clock and 12 o’clock positions making sure the blocks are in close
contact with the disc but not supporting the valve.
3. Remove the packing gland by removing the retaining screws and sliding the gland off the top of the
stem.
4. Remove bottom plate and thrust bearing to expose bottom of stem.
5. Remove nuts and washers from ends of taper pins and drive taper pins out of the disc. Avoid damag-
ing the disc coating or surface when removing taper-pins.
6. Once taper-pins are removed, drive the stem, bushing, and packing out of the valve body through the
top.
7. Remove the disc from the seat, protecting disc edge at all times.
Note: Valve is provided with the seat bonded to the body and therefore is not easily eld re-
placeable. Please contact your local Bray representative for seat replacement.
