PRODUCT DESCRIPTION
• Screw-type couplings specially designed for very high static pressure applications on cylinders and hydraulic rams
• Connection and disconnection is made by screwing the sleeve and can be made with residual pressure in the line
• Connection secured on the thread between the sleeve and the male coupling
• Shut-off by poppet valve provides effective hydraulic sealing
• Interchangeable with other products and widely used in the USA and Europe
• ISO 14540 compliant
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)
Specific seals available in case of higher temperatures
SAFETY FACTOR
4:1 for dynamic pressures
IMPULSE PRESSURES
10,000 cycles at 100% of the rated one (freq. 1Hz)
