FUEL SWING CHECK VALVES

The valve is spring-loaded to the normally closed position to provide motive flow line isolation from downstream equipmentlines 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.
