Non-spill quick couplings for cooling in railway sector SPT/CG

The non-spill, flat face design of SPT CG quick couplings ensures that there is no ingress of air into the circuits on connection, and no loss of liquid on disconnection. These connectors are made from high-performance treated aluminum alloy, which makes them strong as well as lightweight. Their interior design ensures low pressure drop for optimum flow within compact overall dimensions. Safe and reliable, these fluid couplings ensure extremely robust locking.

 

APPLICATIONS

  • Cooling and thermal management of onboard electronic equipment, engines and transformers
  • Filling and draining circuits
  • Circuit bleeding
Technical specificationsFluidsConstructionOther features
  • Nominal diameter DN (mm): from 05 to 25
  • Maximum allowable pressure*: 40 bar (580 PSI) 
  • Glycol water
  • Heat transfer oils
  • Esters
  • Aluminum alloy with surface treatment
  • Protective dust caps:
    • Socket: POM and Chloropren (CR)
    • Plug: Chloropren (CR)
  • Optional relief valve on the socket or plug side, which protects the circuits in the event that pressures continue to increase from residual heat
  • SPT 10 and SPT 12 available in multi-coupling versions for simultaneous connection of multiple circuits.
