Eaton Aeroquip FD83 series full flow dual interlock couplings
Product Code: FD83
Eaton’s FD83 is designed for fluid transfer and electronics cooling applications where full flow, fluid compatibility and safety are essential.Eaton’s FD83 is designed for fluid transfer and electronics cooling applications where full flow, fluid compatibility and safety are essential. The FD83 identical halves include two interlock features to eliminate spills and ensure maximum safety. Valves cannot be opened until the coupling halves are mated and coupling halves cannot be disconnected until both halves are closed. The FD83 coupling system can be used in a wide variety of low pressure industrial applications.
Features include:
Full-flow capability
Identical coupling halves
Available colour coded bumper seals available
Applications include: electronics liquid based cooling, thermal management systems, industrial fluid transfer, Sever cooling systems etc.
FD83 Series Full Flow Dual Interlock coupling
FD83 series Full flow dual interlocking coupling
An industry standard, our stainless steel FD83 has been supporting data center liquid cooling reliably for decades.
- Interlock design ensures parts cannot be disconnected while liquid is flowing
- Multiple end connection configurations, including angled hose barbs are available
- Ball valve for full flow and minimal pressure drop
Light-weight, durable engineered composite design available 2021. Offers same operating performance and is interchangeable with current design.
The FD83 coupling from Eaton Corp. targets high flow rate applications where a safe, simple, reliable, dry break connection is required. Typical applications for this type of coupling include computer cooling and bulk fluid transfer, but it can be manufactured in a variety of base materials with alternate seals and end ports for a wide range of fluids and applications.
The FD83 coupling provides improved flow characteristics when compared to typical dry break quick disconnect couplings of equivalent size because there are no valve components in the flow path to obstruct flow. It also eliminates the potential for serious spills that can be caused by sticking valves in standard quick disconnect couplings.
The FD83 dry break couplings are unique in that they feature a Unisex design. The halves are identical so there is no concern for male/female connection relationship of system components, which simplifies operation and inventory requirements. The valve design provides a straight through, unobstructed, flow path for maximum flow and minimum pressure drop. The coupling's two interlock features help eliminate spills and ensure maximum safety. Valves can't be opened until two coupling halves are mated, and coupling halves can't be disconnected until both valves are closed. The ability to swivel 360 degree permits positioning of valve handles and reduces hose twist.
Additional key features of the coupling include minimal spillage on disconnect, and a special locking pin and lever handle to prevent accidental disconnects, and color coded bumpers to avoid cross connections. The one-inch coupling also features 303 stainless steel construction and EPDM O-ring seals with 150 and 300 PSI operating and burst pressures respectively.
