When you need high-performance, reliable fuel swing check valves, you can turn to Crissair, Inc. We are a manufacturer of quality aircraft fluid control components. Our fuel swing check valves are designed with performance in mind and are fully qualified to MIL-V-7899 specifications. Crissair is listed in the QPL 7899-19 specification as a qualified approved supplier for the MS28884B fuel swing check valves. Our fuel swing check valves are often manufactured in sizes ranging from 1/4” to 3” line diameters and are ideal for fuel system applications because of the requirements for high flow rates and low pressure drops. Inside the valve, there is a spring or gravity-loaded hinged disc against a flat surface that opens to allow forward fuel flow and closes in the reverse direction to eliminate backflow. These are crucial components for aircraft fluid control. WHY TRUST IN CRISSAIR, INC.? At Crissair, Inc., our ultimate goal is to provide you with high-quality and reliable aircraft fluid control components. We work with airframe manufacturers and major subcontractors in the industry, providing products for both military and commercial aircrafts.
