The CG-LOK Tank Unit (Flange) Dry Disconnect Coupling is the fixed half of a dry break connection with a bolted ANSI 150 lbs flange, for mounting onto flanged tank nozzles, manifolds and process piping. It carries an internal valve that stays shut until a CG-LOK hose unit is locked on and turned to open, and closes again before the units part. The flanged connection suits larger bores and permanent installations where a bolted gasketed joint is the plant standard.
Key Features
• Tank side (TU) unit with ANSI 150 lbs flange for mounting to flanged nozzles and manifolds
• Internal valve remains closed unless a hose unit is locked on and opened
• Suited to larger bore and permanent installations following flanged piping standards
• Sizes 1″, 2″, 2½”, 3″, 4″, 6″ and 8″, other flange types available on request
• Stainless steel 1.4408, aluminium or brass bodies, ATEX and PED certified
Specifications
• Body materials: stainless steel 1.4408 (cast SS316 equivalent), aluminium, and brass
• Working pressure: 25 bar (363 psi) stainless steel, 16 bar (232 psi) brass, 10 bar (145 psi) aluminium
• Test pressure: 37.5 bar stainless steel, 24 bar brass, 15 bar aluminium
• O-ring seals: FPM rated -35°C to +140°C on stainless steel, NBR rated -30°C to +100°C on aluminium
• Flat seal: PTFE rated -25°C to +250°C
• Sizes: 1″, 2″, 2½”, 3″, 4″, 6″ and 8″
• Certification: ATEX, PED 2014/68/EU, and 3.1 material certificate available
How It Works
Operation is a two stage turn that keeps the valves shut until the connection is secure. Turning the hose unit 15 degrees clockwise locks the two units together while both valves stay closed. Turning a further 90 degrees opens the internal valves and allows flow. Reversing the sequence closes the valves before the units separate, so product is contained on both sides at the moment of disconnection.

Frequently Asked Questions
Can this be fitted to an existing flanged tank nozzle?
Yes, provided the flange standard and size match. The standard offering is ANSI 150 lbs in sizes from 1 inch to 8 inch, and other flange types can be supplied on request to suit your existing nozzle.
What certification is available for these couplings?
CG-LOK dry disconnect couplings carry ATEX certification and PED 2014/68/EU compliance, and a 3.1 material certificate can be supplied on request for traceability.
What working pressure does the flanged tank unit handle?
Working pressure depends on body material: 25 bar for stainless steel 1.4408, 16 bar for brass and 10 bar for aluminium, tested at 37.5, 24 and 15 bar respectively.
