Common questions
Will this fit an older hand expansion valve?
Parker notes that the new hand expansion valve plugs and bonnet assemblies will not retrofit to a prior design hand expansion valve body or prior design expansion valve. Match the size, connection and body style to the 82-00 C parts tables.
Specifications are based on Parker Refrigerating Specialties Bulletin 82-00 C (Hand Expansion Valves, HEV) and the Parker R/S Parts Kits list PK-16. Confirm fit, ratings and application requirements before ordering.
