York 364-47667-013 Valve Kit

The York 364-47667-013 Top Head Valve Kit is a York Applied service kit in the 364-47667 series of top head valve kits. The top head is the head assembly at the top of the compressor's cylinder, where the valve section sits, so a top head valve kit is the package you reach for when the valves in that assembly are worn and the head has to come off anyway. It is the same family as the 364-47667-009 Top Head Kit and the 364-47667-006 Top Head Valve Replacement Kit, and each of those is a separate number with its own contents.

The job of the top head valve section is simple but unforgiving. The suction valve opens to admit gas on the intake side of the compression cycle and closes before compression begins; the discharge valve opens only when cylinder pressure exceeds the discharge side and closes again so high-pressure gas cannot flow backward. Valve springs control how those valves move, and the gaskets between the cylinder head and the valve seats keep each side sealed. For a documented example of what a series kit contains, the 364-47667-006 kit lists valve springs, gaskets, a suction valve ring and a discharge valve ring. The 364-47667-013 sits in the same numbering family as the carried 364-47667-009 Top Head Kit, the 364-47667-010 Valve Kit and the 364-47667-006 Top Head Valve Replacement Kit. Each dash number is its own service kit, so the full part number matters: match it to the kit called for on your compressor's parts list rather than substituting a neighboring number.

Plan the work around the failure symptoms: reduced pumping capacity, a suction pressure that will not drop, high discharge temperature, longer run time and pressures that equalize quickly after the compressor stops all point at leaking suction or discharge valves. Recover the refrigerant, lock out the power, and pull the cylinder head so you can inspect the valve seats and sealing surfaces. Replace the gaskets and valve hardware as a set, clean every sealing surface, assemble per the manufacturer's procedure, then leak test and evacuate before you start the system.

Key Benefits

• Top Head Valve Kit: Catalogued by York as a top head valve kit, so it targets the valve section in the cylinder head assembly.
• Replace as a Set: Replacing valve hardware and gaskets together avoids chasing a second leak a few weeks after the first repair.
• York OEM Numbering: The 364-47667-013 number ties directly to York's service kit series, so you can order against a parts list instead of guessing.
• Clear Series Context: Sibling kits 364-47667-006, 364-47667-009 and 364-47667-010 are separate listings if your compressor calls for a different one.

Common Questions

• What does a top head valve kit do? It replaces the worn valve hardware in the cylinder head assembly so the suction and discharge valves seat and seal again.
• What are the signs the valves are bad? Low pumping capacity, a suction pressure that will not pull down, high discharge temperature, long run time and pressures that equalize quickly after shutdown.
• Can I substitute a neighboring dash number? Not by number alone. Each dash number is its own kit. Match the full part number to your compressor's parts list.
