Valve assembly keeps nutrient out of moving parts of valve by physically isolating plunger from fluid. Poppet and diaphragm are molded together, and latter is shaped to act as static seal, which remains seated during the operation. As plunger moves, diaphragm also moves to form separate cavity for nutrient and thus isolates it from plunger cavity and latching mechanism.
