Spence 07-04164-00 Repair Kit

Maintaining a precise set point on your critical steam or air systems requires a Spence 07-04164-00 Repair Kit that is specifically engineered for D-Pilot pressure reducing valves. As a veteran technician, you know that SPS spring pilot regulator maintenance is non-negotiable for preventing erratic pressure swings and ensuring dead-end shutoff. This comprehensive Spence D-Pilot overhaul kit includes the essential internal components—such as the stainless steel stem, seat ring, and disc—required to restore the frictionless operation these pilots are known for.

The kit is compatible with Spence SPS Spring Pilot models 4NU80, 4NU81, and 4NU82, and includes three diaphragms (note that SPS-30 and SPS-60 models typically utilize only two). By replacing the inconel valve spring and high-temperature gaskets included in this set, you eliminate leakage at the diaphragm flange and ensure the D Series pilot operator maintains its ±1 psi regulation accuracy. This is the standard HVACR steam pilot repair solution for contractors looking to avoid the downtime associated with faulty pressure regulation in Type E or Type C main valve assemblies.

• OEM Compatibility: Specifically designed for Spence D Series pressure reducing pilots and SPS spring pilot variations.
• Rugged Internals: Includes a durable stainless steel stem, inconel valve spring, and seco disc for high-heat steam applications.
• Precision Control: Restores factory-spec valve travel (nominally 3/64") to eliminate hunting and ensure stable delivery pressure.
• Comprehensive Components: Features the pusher plate, diaphragm screw, seat ring, and screen needed for a complete in-line rebuild.

Is this kit compatible with both cast iron and cast steel D-Pilots?
Yes, the Spence 07-04164-00 is designed to service the internal moving parts and seals across standard D-Pilot body materials.

Why does the kit include three diaphragms if some models only use two?
The additional diaphragm provides flexibility for different pressure ranges; technicians should consult the specific Spence pilot manual for the SPS-30 or SPS-60 to determine the exact layering required for the adjusting spring range.

Does this kit include the 05-02416-00 adjustment gauge?
While often supplied with new pilots, this repair kit focus is on the wear components like the seat ring and gasket. Always verify the 11/64" pusher plate dimension during reassembly to ensure proper stem stroke.
