The plug side carries the coupling plugs of the plate and is mounted on the moving half of the changeover station. As the halves close, all plugs enter the socket plate at the same time. The letter P in the model code marks the plug version. Model MAM-A-3P12-CL, aluminium.

Where a changeover station has to release several media lines at once, coupling each line on its own costs time and invites mix-ups. The Nitto Kohki Multi Cupla Zerospill combines 2, 3 or 4 coupling elements in a single plate and parts them in one movement, without medium escaping at the parting line.

  • Versions with 2, 3 or 4 coupling elements per plate, so the element count can be matched to the number of lines at the station
  • All lines are connected and disconnected in one operation, which rules out swapping individual lines
  • Zerospill design for drip-free disconnection, the medium stays inside the line when the plates part
  • Aluminium plate bodies keep the weight of the moving unit down, the single MAM-A-ZEL coupling elements are made of brass
  • Seals in NBR or FKM, the sealing material is chosen to suit the medium carried
  • 22 variants across the MAM-A and MAM-B plate ranges and the single MAM-A-ZEL coupling elements

Operating principle

Two-way shut-offTwo-way shut-offshut-off valve in socketshut-off valve in plugSocketPlugFlow direction: socket to plug
Both halves close on disconnection, so the line contents are retained on both sides.
  • Unique seal design reduces both liquid spillage and air ingress.
  • New valve design offers smooth zero-friction movement, resulting in reduced chance of malfunction caused by deterioration of valve parts.
  • Push to connect design: just push the plug into the socket for simple and secure connection, which reduces connection time and improves efficiency.
  • One-hand easy operation.
  • A variety of body materials and sizes have been standardized to support a wide range of applications and situations.
  • Automatic shut-off valves in both socket and plug prevent fluid spill out on disconnection.
  • Volume of spillage about 96 percent less compared with SP CUPLA Type A.
  • Volume of air ingress about 94 percent less compared with SP CUPLA Type A.

Pick ZEROSPILL CUPLA when disconnection must not spill: it shuts off on both sides with spill reduction, and the catalogue figures put its spillage about 96 percent and its air ingress about 94 percent below SP CUPLA Type A, the two-way shut-off sibling in the same category. Its working pressure stops at 3.5 MPa {35 kgf/cm2}, so lines that go up to the 7.5 MPa {76 kgf/cm2} of TSP CUPLA or SP CUPLA Type A are outside its range. TSP CUPLA is straight through and TSP CUPLA Socket with Ball Valve shuts off on one side only at 1.0 MPa {10 kgf/cm2}, so neither of them holds the fluid back in both halves the way this series does.

  • Changeover units where several media lines are released together
  • Tool and fixture changes with 2 to 4 supply lines
  • Test and assembly stations where the line assignment has to stay unambiguous
  • Lines that must not release any medium when parted
