MODEL 52250: SAFETY RELIEF VALVE – 250 PSI POP-OFF – 1/4" NPT

ULTIMATE OVER-PRESSURE PROTECTION POLICY

Safeguard your heavy-duty pneumatic investment with the premium Kleinn Model 52250 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 250 PSI, eliminating catastrophic over-pressurization risks.

THE AUDIBLE ALARM EARLY WARNING FAILSAFE

The Model 52250 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 52250 Safety Relief Valve?

Built for Extreme 200 PSI Architectures: Calibrated specifically to safeguard high-pressure configurations operating around a 200 PSI maximum operational ceiling 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 250 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 high-pressure configurations. The Model 52250 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 52250 Safety Valve is specialized hardware optimized exclusively for high-output systems running an extreme 200 PSI max framework. To prevent premature venting or system leaks, this valve should always be paired with heavy-duty compressors and pressure switches engineered to cut out at 200 PSI.

Confirmed Kleinn Component Compatibility Matrix:

Compatible Heavy-Duty Systems: Engineered for extreme duty configurations rated up to 200 PSI.
Mandatory Matching Component: Engineered to pair with the Model 2165 Sealed Pressure Switch (200 PSI Cut-Out) for automated system safety harmony.

What's Included in the Box

Safety Valve: One (1) Model 52250 – 250 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.
