Common questions
Will this fit an older Parker hand valve?
Parker notes that the current hand shut-off valve plugs and bonnet assemblies will not retrofit to prior design hand shut-off valve bodies or prior design stop valves. Match the valve size, connection type and body style to the 80-01 L parts tables before ordering.
Why use an extended bonnet?
Parker designs extended bonnets for insulated lines, so the hand wheel or seal cap sits outside the insulation.
Specifications are based on Parker Refrigerating Specialties Bulletin 80-01 L (Hand Shut-Off Valves) and the Parker R/S Parts Kits list PK-16. Confirm fit, ratings and application requirements before ordering.
