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 for all industrial applications
• Simple connection and disconnection by pulling back the sleeve
• Positive, quick connection of the male into the female by latching the ball system
• Shut-off by poppet valve
• High resistant materials
• Interchangeable according to ISO 7241 series B

MATERIAL

Female couplings in steel, with some hardened areas, in correspondence to the most stressed points. Male couplings in high grade carbon steel hardened. Springs in C98 steel, seals in NBR (other materials on request) and back-up ring in PTFE

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)
