OPERATING INSTRUCTIONS:
These products are designed to operate as Dry Disconnect couplings. They are to be used in place
of standard couplings when it is desired to prevent product from spilling from the fittings upon
disconnect. This product is not intended to be the primary flow control or flow shut off device. Just
as with standard non-dry disconnect fittings, it is intended that a flow control and flow shutoff valve
will be installed in the system.
To use these fittings, attach the coupler to the mating adapter by aligning the three bayonet studs
with the three corresponding notches in the adapter. Push the coupler onto the adapter and rotate
clockwise about 20
clockwise until the coupler stops rotating.
To open the fittings, rotate the lever on the coupler approximately 190
counterclockwise until it
moves into an over center position and remains in place. At this time, the flow control valve can be
opened to transfer product.
After the product has been transferred, close the flow control valve, then rotate the coupler lever
clockwise until it returns to its over center closed position and remains in place. Rotate the coupler
about 20
counterclockwise until the coupler stops rotating. Separate the coupler from the adapter.
Care must be taken in the design of the piping system to avoid trapping liquid between a shut off
valve and a Dry Disconnect Coupler or Adapter. If liquid is trapped in this manner and the
temperature increases, the pressure in the closed volume will rise dramatically and the Dry
Disconnect fitting will be damaged.
DISASSEMBLY INSTRUCTIONS:
WARNING: When assembling or disassembling these products, always
wear safety glasses. Severe eye injury may result if not wearing safety
glasses.
1. If you are repairing the swivel seals or wish to remove the swivel to gain better access to the
i
nside mechanism, proceed as follows… (Note you must remove the elbow style swivel to
repair the shaft seals.
a. Remove the BALL PLUG.
b. Remove the BALLS by holding the access hole pointing downward over a cup and
rotating the MAIN BODY. A small cylindrical magnet may be useful to help remove
balls that are stuck in the grease.
c. After all balls have been removed, pull the swivel axially from the BODY.
2. Remove the BUMPER RING by heating with an industrial heater to soften the material.
3. Depress the LOCK RING and rotate clockwise to disengage it from the BAYONET STUDS.
4.
Remove the BAYONET STUDS by holding the head with an “Allen” wrench while loosening
the JAM NUT holding the BAYONET STUD.
