PRODUCT DESCRIPTION
• Historical series for the agriculture market
• 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 with similar products available on the market (½” size according to ISO 7241-1 series A)
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)
