The rated flow represents the normal operating condition. The maximum recommended flow rate is equal to 1.5 times the rated flow

PRODUCT DESCRIPTION

• Reference series on the agriculture and industrial market
• Simple connection and disconnection by pulling back the sleeve
• Positive, quick connection of the male into the female by the latching ball system
• Shut-off by poppet valve
• High resistant materials and hardened male and sleeve to withstand the brinelling effect
• Interchangeability according to ISO 7241 series A

MATERIAL

Female and male couplings in steel, with some hardened areas, in correspondence to the most stressed points. Springs in C98 steel, seals in NBR (other materials on request) and back-up ring in PTFE. PU seal on ½” female available on request.

WORKING TEMPERATURE

-22ºF up to +230ºF (-30ºC up to +110ºC)
For other temperatures, the coupling may be assembled with the specific seals

SAFETY FACTOR

4:1 for dynamic pressures

IMPULSE PRESSURES

100,000 cycles at 133% of the rated one (freq. 1Hz)

TEST SPECIFICATIONS

ISO 18869
