Valve with conical poppet modified to incorporate smooth transition to segment of sphere at upstream end of cone. Constitutes sealing surface of poppet; results in leak rate equivalent to ball-type poppet, and extremely low flow losses. Also enables use of loose fit for guiding poppet, with resulting lower manufacturing cost, high reliability, and long operating life.
