For air / water Plate with CUPLA for multiple and simultaneous piping

For improved safety and reliability
Piping changes within limited lead time increase the probability of connection errors and impair the safetyof the work area. MULTI CUPLA removes the possibility of connection errors in multiple pipe connection
systems by its own design and by the connection system it is constructed on. Safety and reliability inpiping works can be enhanced further with the introduction of remote-control operation.
Reliable solid
connection forports separated
with longer
distances.

For space and energy saving, and clean factory site
Individual manual piping systems do not have a well coordinated piping area and thus yields working loss
due to piping disorders. MULTI CUPLA design realizes centralization of pipe connections, consolidationof piping circuits, space saving, energy saving, and a clean working environment.

- Compared with conventional MULTI CUPLA, approximately double
flow rates are realized. This could reduce the size of required plates.
(Rate of flow increase depends on CUPLA sizes.)- The MALC type realizes a 2 mm axial eccentricity allowance,
while conventional MULTI CUPLA is only 0.6 mm.
- Special valve design enables connection of socket and plug underpressure of up to 2 MPa. (up to 1.5 MPa for MALC-12SP.)- When connected, the distance between the socket plate and the plug
plate is designed to be 30 mm for all sizes. This means that any sizeof CUPLA can be mounted and used on the same plate.
- Low spill valves minimize outflow of fluid and admixture of air into
the fluid line.

Two-way shut-off(Spill Reduction)

Maximum Tightening TorqueHydraulic oil

A single operation enables
simultaneous connections ofmultiple lines. A special design
minimizes air admixture in fluidlines upon connection. Suitable forhigh pressure hydraulic circuits.
- Compared with conventional MULTI CUPLA, approximately double
flow rates are realized. This could reduce the size of required plates.
(Rate of flow increase depends on CUPLA sizes.)- The MALC type realizes a 2 mm axial eccentricity allowance, whileconventional MULTI CUPLA is only 0.6 mm.
- Special valve design enables connection of socket and plug underdynamic pressure of up to 8 MPa.
- When connected, the distance between the socket plate and plug
plate is designed to be 30 mm for all sizes. This means any size of
CUPLA can be mounted and used on the same plate.
- Low spill valves minimize outflow of fluid and admixture of air into
the fluid line.

Caution• Prior to use, check the compatibility of the seal material and body material against the temperature and the fluid to be used. Selecting the wrong seal material will lead to leakage.
As to the use of any special paint or solvent, make thoroughly sure of the material compatibility.
• Only use CUPLA that are within their rated temperature range. Otherwise this can lead to leakage through seal deterioration or damage. It cannot be used continuously at its lowest or highest rated working temperature.
• The durability of CUPLA differs depending on the operating environment and conditions (pressure and temperature etc.). If necessary, conduct performance evaluation test under your actual operating environment and conditions.
Also, stress corrosion cracking may occur if used under corrosive environment. Take note of usage conditions.
• When cleaning CUPLA, care must be taken not to use any material that will affect the seal and body materials.
• Apply a fluoropolymer resin sealant tape on male tapered pipe threads to ensure no leak. (Applies to Snap ring mount Type, MAM Type, MAM-A Type, MAM-B Type)• Do not exceed the recommended maximum torque when screwing in to the male or female thread of CUPLA for installation. It will cause damage.
• Prior to use, always perform a leak test after installing CUPLA.
• Always install a shut-off valve between the pressure source and CUPLA.
• Do not use with any fluid or medium other than what is specified, to do so could cause leakage or damage.
• The use of inline filters is strongly advised and recommended. To prevent damage, the fluid should be clean before reaching CUPLA.
• Do not use CUPLA in areas or environment where dust such as sand or metal powder can get in to CUPLA. It will lead to malfunction or leakage.
• Do not let paint stick to CUPLA. It will cause malfunction or leakage.
• Be careful not to put scratches or dents on CUPLA. Scratches on the sealing parts will cause leakage.
• Do not apply any artificial impact, bend or tension. It will cause leakage or damage.
