Multi-Part Valve Assembly

A valve assembly comprising:

• an insert retainer comprising a circular retainer head and a retainer pin extending downward from the retainer head;
• the retainer pin comprising:
• a cylindrical upper section extending below the retainer head;
• and,
• a cylindrical and grooved center section extending below the upper section;
• a valve centered on the upper section of the retainer pin, adjacent to the retainer head;
• a polymer insert located on an exterior perimeter of the valve and beneath the retainer head;
• a guide having a central portion on its upper end and four legs extending downward from the central portion;
• the guide central portion centered on the retainer pin beneath the valve;
• and,
• a collar comprising:
• a flange;
• a collar body extending below the flange;
• and,
• a bore extending through the flange and the body;
• the collar being located beneath the guide central portion;
• the bore within the body of the collar swaged into the center section of the retainer pin;
• and,
• the ratio of the diameter of the flange to a diameter of clearance on the central portion is between 0.770 and 0.775.
