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

PRODUCT DESCRIPTION

• Screw-type couplings specially designed for truck trailer applications
• Wing Nut shaped sleeve for easier connection and disconnection by hand, also in case of residual pressure in the line
• Connection secured on the thread between the sleeve and the male coupling
• Shut-off by poppet valve
• Interchangeable with similar products available on the market

MATERIAL

Female and male coupling in steel. Carbonitrided valve, springs in C98 steel, seals in NBR (other materials available on request) and back-up ring in PTFE

WORKING TEMPERATURE

-22ºF up to +230ºF (-30ºC up to +110ºC)

SAFETY FACTOR

4:1 for dynamic pressures
