September 27, 2019 - Valcor Engineering Corporation, a designer and manufacturer of fluid control components and subsystems, clutches, brakes & OBIGGS systems, introduced a new product line capability: Quick Disconnect (QD) couplings.
Quick Disconnect couplings are designed for demanding aerospace applications with high pressure, high vibration, and large temperature extremes. These couplings have a large flow capacity, and minimal liquid loss during the unmating process. Valcor’s QDs are custom designed for specific applications. Therefore, material selection and line sizes can vary.
Current QD designs are non-locking type, that require contact to maintain the couplings in the open position. Upon pulling the QD apart, each end closes and maintains the gas/liquid on each side of the fitting. They are capable of meeting low leakage requirements in high vibration environments. Current designs use tube stubs at the inlets and outlets for welding capabilities, with a 4-bolt flange. Valcor can also provide standard male AN fittings.
