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

PRODUCT DESCRIPTION

• Connectable with male (ISO A) and female under pressure
• High working pressure 30MPa
• Simple connection and disconnection by pulling back the sleeve
• No shut-off, Manuli mechanical valve block system
• Installations on hoses, pipe and direct to port
• Wide range of termination ends
• Interchangeable according to ISO 7241 series A

MATERIAL

Female couplings in steel, with some hardened areas, in correspondence to the most stressed points. Carbonitrided valves and sleeve, springs in C98 steel, seals in NBR and polyurethane (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

500,000 cycles (connected and disconnected conditions) at 120% of the rated one (freq. 1Hz)
