PRODUCT DESCRIPTION

• Screw-type couplings specially designed for heavy duty, high pressure, pressure impulse applications such as hammers, attachments, rock crushers, etc.
• Connection and disconnection is made by screwing the sleeve, also possible with residual pressure in the line
• Connection secured on the thread between the sleeve and the male coupling
• Shut-off by poppet valve
• Hexagon around the male insert to be tightened up or released for maintenance
• Interchangeable with similar products available on the market
• Up to size DN 20 ISO 14541 compliant

MATERIAL

Female coupling in steel, male couplings high standard carbon 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

IMPULSE PRESSURES

200,000 cycles at 133% of the rated one (freq. 1Hz) disconnected; 500,000 connected
