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 ball valve
• High resistant materials
• Interchangeable with poppet valve standard series and 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. High-resistance latching balls, springs in C98 steel, seals in NBR 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)
