Fuel Swing Check Valves

The fuel swing check valve is an inline, swing flapper check valve that has many uses; one of which is to prevent reverse fuel flow from the ejector pumps to the engine feed subsystem.

Description
    The valve is spring-loaded to the normally closed position to provide motive flow line isolation from downstream equipment/lines when the motive flow supply is non-operational. This elegantly simple design is extremely reliable and several variations of this valve have been produced by Parker for over 30 years.

    A fuel swing check valves is an ideal choice if surge pressures and any hammering effects are an important design consideration. This valve is typically installed horizontally and with the hinge up so that in the unlikely event the torsional spring should break, the valve shall fail close. With its low pressure drop and low leakage rate, this valve is an ideal choice when properly selected for the right application.

    The material and finishes used in the construction of the valve and those of similar, previously qualified valves are unaffected by several environmental conditions listed in RTCA DO-160 and MIL-STD-810.

    APPLICATIONS:
    Commercial aircraft, military fighters and transports, business and general aviation.

    FEATURES AND ATTRIBUTES:
    Fundamental features of the fuel swing check valve include the following:
    • Very low pressure drop
    • Internal components are completely shielded by an aluminum alloy body from the environment
    • Low Internal leakage
