A valve comprising

• a one-piece plastic body having a central cylindrical portion extending along a first axis, a tubular outlet portion extending along a second axis parallel to and offset from the first, said central portion and said outlet portion having bores which intersect only over a portion of the length of each, and a tubular inlet extending along a third axis perpendicular to the first axis and above the intersected portion of the central bore that an uninterrupted 360.degree. band portion of the central bore, forming a seat remains between the outlet and the inlet, and
• a plunger assembly including a resilient, circumferential lip thereon, and a circumferential recess adjacent thereto of lesser diameter than said central bore, said plunger being movable between a closed position in which the lip abuts the 360.degree. band, and an open position in which the lip extends into the intersected portion of the bore, and the recess provides a flow channel between the outlet and the inlet.
