Liquid dispensing valve and method with improved stroke length calibration and fluid fittings

摘要

A liquid dispensing valve includes a valve body, a valve seat, and a reciprocating valve member engageable with the valve seat for controlling flow through a liquid outlet. A calibration device includes a rotatable stroke control stop member and a rotatable reference ring. The reference ring and stop member may be initially rotated to a zero position and, subsequently, the stop member may be rotated to set the desired stroke length. One or more fluid fittings are provided and sealed against the valve body using a clamp plate.
