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.
