ABSTRACT:
A dispensing valve includes a body defining a passage with a first opening and a second opening. The body further has an outer surface with a lock surface and an open surface. A pluger is slidably disposed within the passage for movement between a first position wherein a fluid tight seal is formed between the plunger and the body for preventing fluid flow between the first opening and the second opening, and a second position wherein fluid flow is permitted between the first opening and the second opening. An arm extends from the plunger and includes a projection slidably engageable with the outer surface of the body. The arm includes biasing structure for biasing the projection against the outer surface of the body. The projection is engageable with the lock surface when the plunger is in the first position for maintaining the plunger in the first position. The projection is engageable with the open surface of the body when the plunger is in the second position for maintaining the plunger in the second position. Finger pads and finger grips are provided on the plunger and the body to operate the plunger between positions with a single hand of the operator.
