Abstract
Disclosed are trap valve assemblies for controlling flow from a toilet bowl to a trap way. In one form there is a cartridge unit positionable immediately below a toilet bowl discharge outlet. It has a pivotable gate in a form of a spherical segment. The gate has an eccentric pivoting motion so that it can swing from an open position to a blocking/closing position in which it fully contacts a sealing gasket. The spherical segment has a leading edge which is approximately between +40° and −40° from vertical when the gate is in an open position, to minimize the energy required to close the gate. In another form a ball and socket connection to the gate valve facilitates sealing.
