Air-driven Mechanism for Plug Disconnection (High Pressure Version)

Auto Cupla ACV-HP TypeSuits for refrigerants that require high pressure.
High pressure version of the ACV type.
Automatic Plug Disconnection Type.
Contributes to energy and labor saving on theproduction line.
• Simply push the plug into the Auto Cupla for connection.
• Air-driven mechanism is employed in the Auto Cupla to disconnect the plug.
For an emergency, manual disconnection is possible.
• An automatic shut-off valve in the Auto Cupla prevents fluid from spillingon disconnection.
• The ACV-HP type can be connected to the standard 2P-V and 3P-V Plugs.
The ACV-HP-GN type is also available for the 2P-V-GN and 3P-V-GN Plugson request.

A general rule for identification• An Auto Cupla with CR seal:
The body is coated with blue colored anodic oxidized alumina.
• An Auto Cupla with HNBR seal:
The body is coated with red colored anodic oxidized alumina.
• Please contact us should you require any other color.

SocketDisconnection of Plug
Prior to disconnecting the plug, reduce the fluid pressure below 1.0 MPa(10 kgf/cm2). The plug can be automatically disconnected by applying air
pressure of 0.5 to 0.6 MPa (5 to 6 kgf/cm2) to section A.

Air-driven Mechanism for Valve Opening / Closing and Plug Disconnection

Auto Cupla AC Type

Auto Cupla automatically opens and closes thevalve, and disconnects the plug.
Contributes to energy and labor saving on theproduction line.
• Air-driven mechanism is employed in the Auto Cupla to connect anddisconnect the plug and to open and close the valve.
• An automatic shut-off valve in the Auto Cupla prevents fluid from spilling ondisconnection.
• The unique air-driven mechanism reduces the load when the plug is connectedto the Auto Cupla.
• The Auto Cupla and Plug can be connected or disconnected even when theresidual pressure remains.
• The safety design prevents the valve from opening even if the valve isoperated to open with air-driven mechanism without connecting to the plug.
• The AC type can be connected to the standard 2P-V and 3P-V Plugs.
The AC-GN type is also available for the 2P-V-GN and 3P-V-GN Plugs on request.
• Hydrogenated nitrile rubber (HNBR) is colored in blue for easy recognition.

A general rule for identification• An Auto Cupla with CR or NBR seal:
The body is coated with blue colored anodic
oxidized alumina.
• An Auto Cupla with HNBR seal:
The body is coated with red colored anodic
oxidized alumina.
• Please contact us should you require any other color.

How to UseConnection to PlugThe balls in the Auto Cupla become loose by applying air pressure of 0.5 to
0.6 MPa (5 to 6 kgf/cm2) to section A. The plug can then be easily inserted.
Completely inserting the plug into the Auto Cupla and reducing the pressure
on section A to 0 MPa will lock the Auto Cupla and plug and complete theconnection. (* The valve is not open in this state.)
