HNR-DL/DLD Flat Face series
TECHNICAL FEATURES AND OPTion
● Interchangeability: Songqiao internal Standard
● Mechanical connection: Internal cams and locking pins
● Connection system: Rotating the lever
● Disconnection system: Rotating the lever
● Construction material and surface treatment:Body plates in aluminum alloy oxidation Cams and pins in high resistance carbon steel with special heat treatment.
Others components in carbon steel with zinc plating or zinc nickel treatment.
● Mechanical connection: Internal cams and locking pins
● Connection system: Rotating the lever
● Disconnection system: Rotating the lever
● Construction material and surface treatment:Body plates in aluminum alloy oxidation Cams and pins in high resistance carbon steel with special heat treatment.
Others components in carbon steel with zinc plating or zinc nickel treatment.
TO CONNECT
● Before to couple clean the flat mating surface of the
couplings to avoid the inclusion of dirty in the circuit.
● Insert the guidance pins of the mobile multicoupling in
the holes of the fixed multicoupling and move themobile
half till the contact of the couplings faces (fig. 1).
● Acting on the handle turn the lever in the direction of
the fixed multicoupling (fig. 2).
● Continue to rotate till the safety lock automatically
engage itself (fig. 3).
● Now the multicoupling is coupled and ready to work.
In case of connection with residual pressure in the circuit
,the maximum force is required only for the last third of the
connection.
TO DISCONNECT
● Push the red safety button, at the same time acting on
the handle turn the lever in the direction of the mobile
multicoupling (fig. 4).
● Continue to rotate till the mechanical stop of the levers
(fig. 5)
● Now the multicoupling is uncoupled and it is possible to
pull out the mobile half (fig. 6).
● When the fixed multicoupling is mounted upside down,
the mobile multicoupling must be supported in order to
avoid it fall down causing damage.
● In case of disconnection with residual pressure in the
circuit, the maximum force is required only for the first third
of the disconnection.
