Free-flow, nose-to-side check valves with a bypass orifice allow free flow from port 1 to port 2. A customer specified orifice is included to restrict flow from port 2 to port 1. See technical data below for orifice range.

• 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.
• 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.
