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.
Will accept 5000 psi (350 bar) at ports 1 and 2.
Valves with the opposite flow path (free flow from 2 to 1) are considered flow controls and may be found listed as fixed orifice, non-pressure compensated flow
control valve with reverse flow check.
The customer specified orifice diameter is stamped on one of the cartridge's hex faces.
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.
