Sullair Inlet Valve Repair Kit Replacement – 02250166-230

Sullair Inlet Valve Repair Kit Replacement – 02250166-230 Description

The 02250166-230 is a Sullair 5″ inlet valve repair kit designed to rebuild the compatible inlet valve assembly 02250166-128. Sullair parts references identify 02250166-230 as the inlet valve rebuild kit, while 02250166-220 is listed separately as the seal service kit.

The inlet valve controls the flow of atmospheric air into the compressor during loaded and unloaded operation. When the valve operates correctly, it responds to the compressor control system to regulate intake airflow and support stable pressure control.

Over time, seals and other service components inside the inlet valve can wear, affecting valve movement and sealing. Rebuilding the existing valve with 02250166-230 can restore its operating function without automatically replacing the complete inlet valve assembly.

The 02250166-230 kit is associated with the Sullair 02250166-128 5″ inlet valve used in compatible 16 Series applications. Confirm the compressor model, serial number, and original valve part number before ordering.

Sullair Inlet Valve Repair Kit Replacement – 02250166-230 Function

The inlet valve regulates the amount of atmospheric air entering the compressor. It works with the compressor’s control system to manage airflow during loaded and unloaded conditions.

When the inlet valve seals and moves correctly, the compressor can control intake airflow more effectively, maintain the required operating pressure, and transition between operating conditions without unnecessary air leakage.

The 02250166-230 repair kit provides service components for rebuilding the compatible 5″ inlet valve when wear affects its sealing or operating performance.

Sullair Inlet Valve Repair Kit – 02250166-230 Replacement Solutions

01 — Inlet Valve Wear Reduces Airflow Control

Worn internal components can affect the inlet valve’s movement or sealing, making compressor load and unload control less consistent; rebuilding the 02250166-128 valve with 02250166-230 helps restore the valve’s intended operating function.

02 — Air Leakage from a Worn Inlet Valve

A valve that no longer seals correctly can allow unwanted air movement through the intake system, affecting compressor control and operating efficiency; replacing the worn service components helps restore proper inlet-valve sealing.

03 — Unstable Loading and Unloading with 02250166-230

If the inlet valve does not respond correctly to the compressor control system, the machine may experience abnormal loading or unloading behavior; servicing the valve can restore smoother intake-air control.

04 — Inlet Valve Wear During Long-Term Operation

The inlet valve operates repeatedly during compressor load and unload cycles, so internal service components can wear over time; using the 02250166-230 rebuild kit provides a practical way to service the existing valve instead of immediately replacing the complete assembly.

FAQs from Sullair Inlet Valve Repair Kit Replacement – 02250166-230

01 — What does the 02250166-230 repair kit replace?

The 02250166-230 is listed as an inlet valve rebuild kit rather than simply a seal-maintenance kit. The exact components supplied should be confirmed against the current kit specification and your original valve before ordering.

02 — Can I rebuild the inlet valve instead of replacing the complete valve?

Yes, the purpose of 02250166-230 is to support rebuilding the compatible 02250166-128 5″ inlet valve. If the valve body and other reusable components remain serviceable, rebuilding can be a practical alternative to replacing the complete assembly.

03 — How do I confirm whether 02250166-230 fits my compressor?

Check the compressor model, serial number, original inlet valve part number, and valve size against the Sullair parts documentation. Sullair parts references specifically note that the compressor serial number should be provided when ordering parts.

04 — Is 02250166-230 an original Sullair part?

The part number 02250166-230 is identified in Sullair parts documentation as the repair/rebuild kit for inlet valve 02250166-128. Whether the item you purchase is genuine Sullair or an aftermarket replacement depends on the supplier and product source, so confirm product origin if genuine OEM supply is required.
