Sun Hydraulics Check Valve # CKCB-XCN
|
|
|
|
Technical Features
|
This
3 port pilot-to-open check valve and 3 port counterbalance valves are
physically interchangeable (i.e. same cavities, same flow path for a
given frame size). However, cartridge extension dimensions from the
mounting surface may vary.
|
|
|
|
Pilot-to-open
check cartridges are locking valves, not motion control valves. For
motion control applications, use counterbalance valves.
|
|
|
|
Provides hose break protection, prevents loads from drifting and positively locks pressurized loads.
|
|
|
|
For models with manual load release control option, turn load release clockwise to release load.
|
|
|
|
Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit.
|
|
|
|
Corrosion
resistant cartridge valves are intended for use in corrosive
environments and are identified by the model code suffix /AP (see Option
Selection below). External parts are made from stainless steel with
titanium or brass components, where applicable. Internal parts are made
from carbon steel leaded alloy, the same as standard valves. For further
details, please see the Materials of Construction page.
|
|
|
|
Extremely
low leakage. The seat and poppet are heat treated for long life. If
the load drifts due to the valve, the seat has probably been damaged by
contamination and the valve should be replaced.
|
|
|
|
Incorporates
the Sun floating style construction to minimize the possibility of
internal parts binding due to excessive installation torque and/or
cavity/cartridge machining variations.
|
|
|
|
Optional
external porting out of the hex end of the cartridge is available for
external piloting. In this configuration, port 3 is blocked. See
Control options E, and P.
