MODEL 52145: SAFETY RELIEF VALVE – 145 PSI POP-OFF – 1/4" NPT

ULTIMATE OVER-PRESSURE PROTECTION POLICY

Safeguard your heavy-duty pneumatic investment with the premium Kleinn Model 52145 Safety Relief Valve. While electronic pressure monitoring networks are designed to automatically cycle your compressor loop off at a set threshold, mechanical hardware failures can still happen. If an automated pressure control switch becomes stuck in the "ON" position, this mechanical pop-off safety valve acts as your permanent insurance policy—automatically venting storage tank air to the atmosphere the moment internal pressure hits 145 PSI, eliminating catastrophic over-pressurization risks.

THE AUDIBLE ALARM EARLY WARNING FAILSAFE

The Model 52145 is precision-engineered to double as an active acoustic diagnostic tool. If you hear this valve discharging repeated, high-pressure manual blasts of air under the chassis, it serves as an unmistakable early warning indicator that your primary pressure control framework has failed to interrupt current delivery. This immediate acoustic alarm lets you know to safely disconnect auxiliary system power and immediately replace your baseline control mechanism before expensive hardware or structural pneumatic loop lines are compromised.

Why Choose the 52145 Safety Relief Valve?

  • Built for 120 PSI Architectures: Calibrated specifically to safeguard configurations operating around a 120 PSI operational window rather than standard generic commercial relief valves.
  • Universal Tank Mounting: Features standard 1/4" Male NPT threads to thread cleanly and securely into any dedicated side or end port on a Kleinn air storage tank.
  • Precision-Calibrated Pop-Off: Tight structural seal limits air loss during normal cycles, remaining fully primed to vent immediate excess pressure right at 145 PSI.
  • Integrated Manual Pull Ring: Outfitted with a durable split manual ring, allowing operators to manually bleed or test tank storage pressure directly in the field.

THE VERDICT: The definitive safety valve for moderate-pressure configurations. The Model 52145 combines a reliable mechanical pop-off threshold with an audio warning capability, delivering the crucial failsafe backup your system needs to prevent dangerous over-pressurization on the highway or the trail.

⚠️ Important Compatibility Requirements

The Model 52145 Safety Valve is specialized hardware optimized exclusively for systems running a 120 PSI rating framework. To prevent premature venting or system leaks, this valve should always be paired with compressors and pressure switches engineered to cut out between 120 and 125 PSI.

Confirmed Kleinn Component & System Compatibility Matrix:

  • Compatible Air Systems: Model 6260 (120 PSI | 10% Duty Cycle | Ultra Light-Duty)
  • Universal ProBlaster™ Horn Kits: Models HK1, HK2, and HK2-1
  • Vehicle-Specific Upgrades: JEEPKIT-1 and TJ102 system footprints
  • Mandatory Matching Component: Engineered to pair with the Model 2121 Pressure Switch for automated system safety harmony.

What's Included in the Box

  • Safety Valve: One (1) Model 52145 – 145 PSI Pop-Off – 1/4" Male NPT Mechanical Safety Relief Valve.
  • Manual Interface: One (1) Heavy-duty split manual pull ring actuator pre-installed.

🔴 PRO TIP: Keep a permanent seal on your reservoir tank ports. When installing your 1/4" NPT safety valve, avoid over-torqueing into brass tank bungs to prevent stripping the threads. Always apply a few drops of liquid anaerobic thread sealant compound like our genuine Kleinn JUICE across the NPT male lead threads to block out slow, phantom pneumatic pressure drops.
