PRODUCT DESCRIPTION
• Connection is made by pushing the male coupling and disconnection by pulling back the sleeve of the female
• Flat mating surfaces easily wiped clean to prevent contamination and spillage during connection/disconnection
• Stainless steel springs in the female coupling
• Interchangeability according to ISO 16028 and HTMA standards
MATERIAL
Female and male coupling in steel, with some stressed tempered or carbonitrided areas. Springs in AISI and C98 steel, seals in polyurethane NBR. Other materials (VITON, EPDM or any others) on request.
WORKING TEMPERATURE
-22ºF up to +230ºF (-30ºC up to +110ºC)
For other temperatures the coupling is assembled with the specified seals
SAFETY FACTOR
4:1 for dynamic pressures
IMPULSE PRESSURES
100,000 cycles at 133% of the rated one (freq. 1Hz) in disconnected conditions.
1,000,000 cycles at 120% of rated one (freq. 1Hz) in connected conditions.
