DBC 3" Series Dry Disconnects

Operating Instructions

These products are designed to operate as Dry Disconnect cam and

groove couplings. They are to be used in place of standard cam and

groove 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

cam and groove fittings, it is intended that a flow control and flow

shutoff valve will be installed in the system.

1. To use these fittings, attach the coupler to the mating adapter by

opening the two cam arms, sliding the coupler over the mating

adapter and closing the two cam arms. This operation is similar to

using standard cam and groove fittings. Make certain that both cam

arms are fully closed.

2. 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.

3. 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.

4. Open the cam arms and rotate them to the full open position. If the

coupler lever will not remain in the closed position on its own, do not

disengage the cam arms until the piping system and hoses have

been drained.

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.
