ABSTRACT:
A nipple drinker for poultry or the like has a body constructed of thermoplastic acetal (e.g. DELRIN.RTM.) so as to minimize the amount of metal utilized while providing excellent longevity. The drinker includes a valve seat, valve pin, and ball all of metal, such as stainless steel. The head of the valve pin typically is essentially flat, in which case the height of the head is about 1.7 mm when the annular spacing between the circumferential periphery of the head and the valve seat is between about 0.07-0.08 mm. Each and every drinker is individually tested for the integrity of the valve seal, the integrity of an O ring seal, and to determine the amount of water it delivers. Accepted drinkers are classified according to the number of drops of water they will deliver per unit time in use based upon the testing.
