Valve for liquid dispensing system

A valve for a liquid dispensing system, comprising:

• a casing having a first end, a second end, an interior sidewall that extends between the first end and the second end, a liquid inlet positioned at the second end, an outwardly extending mounting flange positioned at the first end;
• a hollow dispensing pin plunger centrally positioned within the casing, the dispensing pin having a first end, a second end, an exterior surface, an interior flow passage, and at least one radial dispensing passage from the interior flow passage through to the exterior surface at the first end of the dispensing pin;
• an annular plunger disposed between the interior sidewall of the casing and the exterior surface of the dispensing pin plunger and engaging both the interior surface of the casing and the exterior surface of the dispensing pin plunger, the annular plunger having a first end and a second end, the annular plunger being movable between a closed position blocking any flow through the at least one radial dispensing passage and an open position toward the second end of the dispensing pin plunger spaced from the at least one radial dispensing passage;
• the dispensing pin plunger being movable between a closed position recessed within the casing with any flow through the at least one radial dispensing passage blocked by the annular plunger and an open position in which the first end of the dispensing pin plunger projects from the casing past the first end of the annular plunger with the at least one radial dispensing passage spaced from the annular plunger;
• a spring positioned between the second end of the annular plunger and the second end of the dispensing pin plunger, the spring acting upon both the annular plunger and the dispensing pin plunger to bias them toward a normally closed position.
