GATHER DBG-CSP

Flat-face sterile coupling

Flachdichtende Sterilkupplung Serie DBG-CSP

Principle: First seal, then release the flow! During the coupling process, the ring valve of the socket and the flat valve of the nipple push against each other. Before the valves release the flow, the interior is shut-off against the environment. The dead space-free design prevents air inclusions when connecting and drip losses when disconnecting.

The robust DBG series represents the top model in its market with over ½ million coupling cycles.

Dry-break, robust and safe for every application
Especially in the pharmaceutical industry, R_a ≤ 0,8 µm
Special product line within the DBG series, DN 6 to 40
Unique in its class

Series DBG-CSP – Flat-face sterile coupling

Technical data

Materials	Stainless Steel (1.4404, 1.4021) Hastelloy^® Titanium
Seals*	FKM, EPDM, FFKM, FVMQ, NBR, CR et al. (also FDA-compliant)
Temperature range	-55 up to +300°C (according to seal type)

^* other elastomers on request!

When coupled, the sterile coupling is shut off to the outside. When disconnecting, it is important that the exposed front-end valve surfaces are not touched by the operator. Cleaning these surfaces, for example with ethanol and a short drying break before re-coupling provides additional safety.

The coupling can be equipped with protection against accidental contact and protective caps as a support.

Advantages

The flat-face design enables non-drip disconnection and inclusion-free connection.

Leakage-free separation and connection of pipe and hose lines under aseptic conditions
Sterizable in-line: no disassembly, no dismantlement required
Suitable for temperatures from -55 to +300°C
FDA-compliant, steam-resistant seals inside the coupling, no damage from the outside
Very good flow behaviour through flow-optimized inner contour
