Quick Connect Couplings - General Information

APPLICATION

SEALEXCEL Stainless Steel Single Valve Quick Connect Couplings are resistance to aggressive environments and corrosive fluids etc and are generally used in many application across a wide sector of Industries such as

» Pneumatic Control
» Air Supply to pneumatic machines
» Automatic devices
» Robotics
» Portable Equipment (Screw-driving & Drilling machines etc)
» Machines or equipment with a high air flow rate (Jacks, Pneumatics Wrenches, Compressors etc.)
» Laboratories (Medical, Pharmaceutical etc.)
» Coachwork, paint shops etc
» Instrumentation

DESIGN

SEALEXCEL Stainless Steel Single Valve Quick connect Couplings have been carefully designed and manufactured to very stringent tolerances under rigid quality control procedures approved to ISO 9001 : 2000 to provide zero leak connection.

FEATURES

» Robust in construction
» Easy for manual connection and disconnection
» No tools required for connection and disconnection
» Reliable leak tight Sealing System
» Durable ball-locking mechanism assures reliable connection
» Valve guide positively aligns valve with seat to prevent leakage.
» Available with nominal flow passage size 5mm, 7.9mm, 10mm and 14mm.
» SEALEXCEL Industrial interchange Plugs are interchangeable with similar Plugs manufactured by other quick coupling
   manufacturers confirming to ISO 6150 Series B and USMIL-C4109 or ANSI(NFPA) T3.20.14-1990 (R2004).
» Available as a standard in a SS316 construction with Flourocarbon 'O' Ring.
» The Quick Connect coupling in material steel with Zinc plated are available on request.

Note:
The stainless steel 316 raw material meets the following specification :
SS316 Bar stock-ASTMA-479 or equivalent.

INSTALLATION PRINCIPLE

During Installation, the Plug part (l) pushes back the Valve (5) to open the air circuit.

When moving into the open position, the Valve releases the Locking balls (6) which move into the groove of the Plug

Simultaneously the outer sleeve (3) moves forward, under spring load (9) and automatically locking the two parts i.e., Plug and Coupler.

Moving the outer sleeve back manually to disconnect, releases the balls which in turn allows the Plug to be withdrawn, permitting the Valve to moves forward automatically closing the circuit.
