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

PRODUCT DESCRIPTION

• MQS-FEH is the flat-face line for extra heavy duty and high vibration applications
• 35MPa of working pressure in connected and disconnected conditions
• Push connection (a click proves correct connection)
• Double-action disconnection process to prevent accidental disconnection – push male and pull back sleeve on female
• 1 Million impulse cycles qualified
• E-Coat 1000 plating

MATERIAL

Female & male couplings in high grade carbon steel with hardened areas in correspondence to the most stressed points. Male vs. female Sealing system in new Polyurethane compound; other seals in NBR with back-up in PTFE.

WORKING TEMPERATURE

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

SAFETY FACTOR

4:1 for dynamic pressures

IMPULSE PRESSURES

1,000,000 cycles at 120% of the rated one (freq. 1Hz)
