Abstract:
1. A liquid dispensing valve comprising: a valve body having a liquid inlet, a liquid outlet, an interior liquid chamber in communication with said liquid inlet and said liquid outlet; a valve seat positioned in said valve body; a valve member mounted for reciprocating movement in said liquid chamber between a closed position engaged with said valve seat to prevent liquid from exiting through said liquid outlet and an open position disengaged from said valve seat to allow liquid to flow through said liquid outlet; a calibration device coupled with said valve member comprising a rotatable reference ring having a first zero reference indicator and additional indicia thereon for indicating incremental increases in stroke length of said valve member, and a rotatable stroke control stop member having a second zero reference indicator and capable of being rotated to change the stroke length of said valve member between zero and a maximum stroke length, wherein said first and second zero reference indicators are aligned to indicate a zero reference after said stroke control stop member has been adjusted to set the stroke length at zero and, thereafter, said rotatable stroke control stop member is rotated relative to said reference ring to set the desired stroke length between zero and the maximum stroke length.
