Abstract
Fluid flow control devices such as drip irrigation or micro-sprinkler valves and emitter unit membranes are constructed of an elastomeric composition selected from the group consisting of (1) a halogenated butyl elastomer, and (2) a diene nitrile elastomer and mixtures of (1) and (2). An ethylene propylene diene elastomer EDPM can also be incorporated into the composition. Use of the compositions inhibits valve and membrane swelling that would otherwise occur when such valves and membranes are contacted by water sources comprising organic and inorganic impurities.
