Abstract
A lightweight, non-metallic valve is preferably formed of molded plastic. The valve has an hour-glass configuration or enlarged recesses formed therein to reduce the overall mass of the assembly and provide increased sensitivity to low flow rates. Sealing O-rings are snap fit into grooves at opposite ends of the symmetrical assembly.
