Dry Disconnect Couplings ambient|Trelleborg Fluid Handling Solutions

ABS Type Approved

Dry Disconnect Couplings are also referred to as Dry Break Couplings or Dry Break Couplers. The KLAW QS Range offers the latest in robust and efficient Dry Disconnect Coupling design.

No spillage on connection and disconnection

The KLAW Dry Disconnect automatic valve open and closure design means there is no spillage on connection or disconnection. This prevents costly clean-up costs.

Time and operating cost savings
The QS features an easy grip and turn action. This improves safety and time efficiency.
QS Dry Disconnect Couplings are much quicker than other connection methods such as bolt up flanges.
No draining of hoses or loading/unloading systems is required – saving on labor and time.

QS Dry Disconnect Couplings: the quick, safe and no spill solution

The market leader in the Marine and Industrial transfer industries is applying its high and exacting standards to this range of Dry Disconnect Couplings.

The robust design and the materials used in the manufacture of QS Dry Disconnect Couplings is more than a match for demanding operating conditions and the rigors of marine and industrial environments.

Dry Break benefits of the KLAW QS

1	Ergonomic single action connection designed for the rigors of repeated time pressure industrial applications and the challenges of offshore environments.
2	Automatic Turn and Lock mechanism ensures the connection is secure and safe.
3	Bump ring to guide and protect.
4	Selectivity system protects against cross-contamination and is fully compatible with existing systems.
5	Built-in swivel removes hose twist and tension. This reduces fatigue on the hose or loading arm and allows the connection process to be much easier for the operator.
6	Industry standards. Designed and manufactured to industry standards.
7	QS Locking Pin is fitted as standard for sizes 2”, 3” and 4”. This safety feature is an additional safety benefit in demanding and fast operating conditions.
8	Completely interchangeable with other manufacturers and existing systems.
9	Automatic valve opening and closure delivers non-spill efficiency: reducing the risk of accidents and avoiding operating clean-up costs.

Selectivity options
The hazard of cross-contamination is caused by the risk of incorrect hose to tanker connection during product transfer. The QS selectivity feature removes this risk and protects against human or procedure error.
The QS selectivity range is industry standard and is therefore completely compatible with current systems.
Selectivity option and specification is determined at the time of ordering.
