Dry-Mate Dry Disconnects 2
OVERVIEW AND FEATURES
The Banjo DM220 & DM300 Series of dry quick disconnect ttings are designed to handle many of the industrial chemicals in use today
with a minimum of uid spillage. The easy to use ball valve design of the ttings allows an unrestricted path for uid ow.
The handles interlock making it easy to identify which handle opens or closes rst.
The Dry-Mate is constructed of glass-reinforced polypropylene for strength and excellent chemical resistance. The PTFE seats and
FKM face seal on the female give the Dry-Mate the same chemical resistance as Banjo’s standard line of ball valves. The face seal on
the female is available in FKM, EPDM and PTFE. The male has all PTFE sealing components.
The over center clamps are easy, quick and positive engagement of the Dry-Mate components. The clamps are 316 stainless steel for
maximum corrosion resistance. The clamps are easily replaceable if damaged.
The Female* has a groove that mates to a rib on the male to provide correct alignment during assembly with the Male**. The two
halves may be rotated 10 degrees either direction with respect to each other and still be clamped together and function properly.
The DM220 & DM300 Series have many safety features to reduce the risk of accidental spillage. Both handles have interlock buttons,
which prevent the handles from opening when the halves are separated and the handles are in the fully closed position. The Female
also has a yoke which keeps the clamp arms in the locked position when the couplers are connected and the handle is in the fully
open position. This prevents the couplers from being separated when the handles are in the fully open position. The gasket that seals
between the two components is mechanically secured to ensure that the gasket stays in place when the halves are disconnected.
Both the Male and Female come standard with a dust cover to keep the balls and seals protected when not in use.

repaired before using in service. Inspect clamps and mating ribs for damage and wear. Bent or
damaged parts as well as excessive wear can adversely affect product performance. Inspect seals
and sealing area on faces of couplers for any signs of damage. All surfaces should be clean and

OPERATION
Step 1
To attach the two halves together, make sure the faces of the Male and Female are free from dirt or other foreign material. Align the two
halves together as shown in Figure 1. The two halves can be rotated 10 degrees either direction with respect to each other as shown in
Figure 2.
Step 2
Slide the Female onto the Male. The alignment groove on the Female will guide the male half into the female half. After the assembly is
together, latch the clamp arms onto the mating rib on the male and rotate the clamp lever toward the female body. This will couple the
halves together and depress the anti-rotation buttons under the handles, which will allow the handles to rotate. After the two halves are
clamped together, the assembly should look like Figure 3.

Step 3
In this position, the handle of the Female must be rotated before the handle of the Male can rotate. Rotate the handle of the Female to
the fully open position. When this handle is fully opened, the locking yoke will engage the cam levers and prevent the cam levers from
being opened while the handle is in the fully open position. The handles should now be oriented as shown in Figure 4.
Step 4
After the handle of the Female has been fully opened, the handle of the Male can be rotated. Rotate the handle of the Male to the fully
open position. The assembly is now opened and ow may begin. When both valves are fully opened the handles should be oriented as
shown in Figure 5.
To close the valves and disconnect the couplers, reverse steps 1 through 4.

WARNING!
As the handle of the Female is being closed and before the handle is fully closed, the locking yoke that
prevents the cam levers from being opened will disengage.
Make sure that the handle on the Female is fully closed before opening the cam levers.
If the cam levers are opened before the handle of the Female is fully closed, liquid may spray or be
discharged,whichmayresultinsignicantinjuryordeath.
