Air Compressor Pressure Switch Control Valve 110-150 PSI - Replacement

In this review the focus is a practical replacement kit for workshop compressors: the Air Compressor Pressure Switch Control Valve with regulator and relief valve. The bottom line: this kit is for DIYers and light shop owners who need a direct, economical replacement to restore automatic cut-in/cut-out control between 110 PSI and 150 PSI. It stands out because it bundles a pressure switch, regulator, gauge and safety valve in one package so you can swap parts without hunting separate fittings or gauges.

Key Features

• 110-150 PSI switch: Provides a clear cut-on and cut-off window so the compressor runs only when pressure drops to the set point, helping protect equipment and limit runtime.
• Adjustment knob: A plastic knob on the inline regulator allows light-touch adjustments for fine tuning downstream pressure for tools.
• Complete replacement kit: Includes the pressure switch, regulator, gauge, safety relief valve and fittings to simplify installation and avoid extra purchases.
• Durable materials: Solid plastic case with aluminum alloy components offer stable performance without needing a full metal control assembly.
• Power saving design: Automatic ON/OFF control reduces unnecessary motor run time which can lower electricity use in intermittent duty applications.

Who It's For

This kit is aimed at home mechanics, hobbyists and small shops that need a direct replacement for a failing pressure control assembly or want a ready-made spare. It works well when the original switch is no longer reliable or if leaks and missing parts make the compressor unsafe.

It is not ideal for heavy industrial systems or installers who require stainless steel, NPT choices beyond 1/4' thread sizing, or OEM-level documentation. Buyers needing factory-grade materials or specialized electrical ratings should look elsewhere.

Pros & Cons

Pros

• Easy to install as a bundled kit, saving time compared with sourcing individual parts.
• Adjustable regulator with a user-friendly knob gives control over output pressure for air tools.
• Automatic red ON/OFF switch and safety relief valve add practical protection for workshop compressors.

Cons

• Some users report mixed impressions of build quality and occasional leakage, so careful sealing and testing is advised.

Specifications

Our Verdict

This replacement assembly is a practical, cost-conscious choice for anyone needing to restore automatic pressure control on a home or light-duty compressor. The bundled regulator, gauge and safety valve reduce installation hassles, and the 110-150 PSI range suits higher-pressure pump models. Buyers should test fittings for leaks and accept that finish and materials reflect a value-oriented part rather than premium industrial hardware.

Frequently Asked Questions

Will this fit my compressor?
It fits compressors that accept 1/4' threaded fittings and use a 110-150 PSI switch range; verify physical mounting and wiring compatibility before purchase.

Does the kit include a gauge?
Yes, the package includes an air pressure gauge along with regulator and safety relief valve.

Is installation difficult?
Installation is straightforward for someone comfortable with basic piping and electrical disconnection, but always depressurize the system and follow safety procedures.
