Operating principle
- MALC-01 Type: Solo use of socket is possible.
- MALC-01 Type: As in the case of MULTI CUPLA MALC-SP type and MALC-HSP type, the distance between the socket plate and the plug plate is designed to be 30 mm when connected. This means MULTI CUPLA MALC-01 type can also be installed mixed with any size of MALC-SP type and MALC-HSP type on the same plate.
- MALC-01 Type: An axial eccentricity allowance of 2 mm eliminates precise centering at installation.
- MALC-01 Type: Compact size with thread screw mount and with flange types available.
- MALC-01 Type: Suitable for operation of ejector pins to open/close valve gates in molding.
- MALC-SP Type: 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.)
- MALC-SP Type: The MALC type realizes a 2 mm axial eccentricity allowance, while conventional MULTI CUPLA is only 0.6 mm.
- MALC-SP Type: Special valve design enables connection of socket and plug under pressure of up to 2 MPa. (up to 1.5 MPa for MALC-12SP.)

Series comparison

| MULTI CUPLA MALC Type | MALC-01 Type: 1.0 MPa {10 kgf/cm2}; MALC-SP Type: 1.5 to 7.0 | MALC-01 Type: one size; MALC-SP Type: sizes 1, 2, 3, 4, 6, 8 and 12; MALC-HSP Type: sizes 1, 2, 3, 4, 6 and 8 | MALC-01 Type: One-way shut-off; MALC-SP Type: Two-way shut-off (Spill Reduction); MALC-HSP Type: Two-way shut-off (Spill Reduction) | Air, Water, Hydraulic oil |

| MULTI CUPLA MAM-A Type | 10 bar | 1/4 inch to 1/2 inch for MAM-A Type plates with CUPLA; 1/8 inch to 1/2 inch for individual CUPLA of MAM-A-SP Type; 1/4 inch to 1/2 inch for individual CUPLA of MAM-A-ZEL Type | Two-way shut-off | Air, Water |
| MULTI CUPLA MAM-B Type | 10 bar | 1/8 inch (8 and 12 port plates), 1/4 inch (6 and 8 port plates) | Two-way shut-off | Air, Water |
| MULTI CUPLA MAS Type / MAT Type and MALC-01 Type | 70 bar | MAS type 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch (R and Rc threads); MAT type M20, M24, M30, M39, M45 thread screw mount; MALC-01 type M14x1 thread screw mount or flange | Two-way shut-off for MAS type and MAT type; One-way shut-off for MALC-01 type | Air, Water, Hydraulic oil |
| MULTI CUPLA MAS Type / MAT Type | 70 bar | 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch (MAS type thread); M20, M24, M30, M39, M45 (MAT type thread) | Two-way shut-off | Air, Water, Hydraulic oil |
MULTI CUPLA MALC is the choice as soon as the pressure class exceeds what the other MULTI CUPLA plates cover: MAM Type ends at 0.7 MPa {7 kgf/cm2}, MAM-A Type and MAM-B Type at 1.0 MPa {10 kgf/cm2} and MAS Type / MAT Type at 7.0 MPa {71 kgf/cm2}, while MALC-SP Type covers 1.5 to 7.0 MPa {15 to 71 kgf/cm2} and MALC-HSP Type 21.0 to 25.0 MPa {214 to 255 kgf/cm2}. Within the range MALC-SP Type and MALC-HSP Type shut off on both sides with spill reduction, so they fit lines where outflow of fluid and air admixture matter, whereas MALC-01 Type at 1.0 MPa {10 kgf/cm2} is one-way shut-off like MAM Type. A further reason for MALC is mixed assembly: the 30 mm plate distance is the same for all three sub-types and all sizes, so one plate can carry different sizes and pressure classes.

| MALC-HSP acceptable distance between socket and plug | 0 to 0.5 mm. Plug and socket must be used in contact with each other. Maximum 0.5 mm distance between socket and plug is acceptable. |
| WAF | WAF stands for width across flats. |
| Flow rate | MALC-01 Type: pressure - flow characteristics chart on page 134 for MALC-01S x MALC-01TP, flow rate axis 0 to 2.5 m3/min (ANR) against pressure 0 to 0.7 MPa {0 to 7 kgf/cm2}, test fluid air. MALC-SP Type: flow rate - pressure loss chart on page 136, flow rate axis 1 to 1000 L/min, test fluid water. MALC-HSP Type: flow rate - pressure loss chart on page 140, flow rate axis 1 to 1000 L/min, test fluid hydraulic oil, fluid viscosity 32x10-6 m2/s, density 0.87x103 kg/m3. |
Interchangeability and size groups
MALC-01 Type: sockets and plugs can be connected regardless of end configurations; not interchangeable with MALC-SP Type (for medium pressure use) MALC-1SP or MALC-HSP Type (for high pressure use) MALC-1HSP. MALC-SP Type and MALC-HSP Type: socket and plug in the same size can be connected regardless of their end configurations. Because the distance between the socket plate and the plug plate is 30 mm when connected, MALC-01, MALC-SP and MALC-HSP of any size can be installed mixed on the same plate.
Safety and application notes
- MALC-01 Type: socket and plug or plate must be used in contact with each other. Maximum 0.5 mm distance between socket and plug or plate is acceptable.
- MALC-SP Type and MALC-HSP Type: plug and socket must be used in contact with each other. Maximum 0.5 mm distance between socket and plug is acceptable.
- For solo use of the MALC-01 socket, the angle of inclination between the socket and the counterpart must be within 0.5 degrees.
- Maintain the connection with the minimum load or more, but not more than the maximum acceptable load. For MALC-01 Type the maximum acceptable load is 500 N {51 kgf}.
- Before use, please be sure to read the Safety Guide described at the end of this book and the Instruction Sheet that comes with the products.
