CXFA

Free flow nose to side check valve

SERIES 2 / CAPACITY: 160 L/min. / CAVITY: T-5A

Free-flow, nose-to-side check valves are on/off circuit components that allow free flow from the inlet (port 1) to the

outlet (port 2) and block flow in the opposite direction.

TECHNICAL FEATURES

Two-port check valves share the same cavity for a given frame size, however, pay close attention as flow paths may be in opposite directions.

Check valves offer extremely low leakage rates with a maximum leakage of less than 1 drop per minute (0,07 cc/min).

Will accept 5000 psi (350 bar) at ports 1 and 2.

Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.

Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION

section). For further details, please see the Materials of Construction page.

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.
