A low pressure drop check valve includes an apertured streamlined guide body 45 mounted on struts which accommodate thermal loading and also includes a streamline poppet or valve member 35 disposed within a housing 15. Forward flow through the valve unseats the valve member, which receives a face 50 of the guide body, allowing flow around the valve member and guide body. Reverse flow is accommodated by the apertures 60 in the guide body, flow through the apertures being applied to a surface of the valve member 35, thereby seating the valve member for blocking such reverse flow. The check valve is also provided with means for minimizing valve member oscillation and bounce. <IMAGE> |
