TECHNICAL FEATURESTECHNICAL 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.

Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids,

greases and lubricants will damage the seals.

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.

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.
