Abstract
A valve assembly (300) comprising a valve body (302) and a mono-material plunger (304). The valve body (302 has a primary opening (314) and a secondary opening (315) that are axially spaced apart. The plunger (304) comprises a primary seal 5 portion (316) and a secondary seal portion (317). The plunger (304) comprises the following operational positions with respect to the valve body: a transit seal position in which the primary seal portion (316) of the plunger (304) is in contact with the valve body (302) in order to occlude the primary opening (314); and a fluid flow position in which the plunger (304) is maintained in the fluid flow position by an external force 10 and a force caused by a pressure differential across the valve assembly (300).
