ABSTRACT:
A check valve (10) and method of assembling semicircular valve discs (38, 40) within blind openings (28, 30) in the valve body (12). A hinge pin (46) for the semicircular valve discs (38, 40) is of a length less than the diameter of the flow passage through the valve body (12) and has sleeves (52) mounted thereon for relative movement between a retracted position for insertion within the valve body (12) and a projected position within the blind openings (28, 30) for supporting the hinge pin (46) and discs (38, 40). A subassembly comprising the hinge pin (46), the semicircular valve discs (38, 40), spring (48), snap rings (60), and sleeves (52) is first formed and then inserted within the valve body (12).
