Poppet Adjustable Relief Valve 100-300 PSI, Brass Pressure Relief Valve

Key features

• Precise Pressure Adjustment This poppet adjustable relief valve comes with a calibrated knurled knob, delivering accurate 100–300 PSI pressure regulation. Clear scale marks let you lock target pressure easily, solving unstable pressure overflow issues on air, water and oil pipelines.
• Standard NPT ConnectionsThe brass pressure relief valve features 3/4” NPT male inlet & 1/2” NPT female outlet, matching most industrial & residential pipe fittings. Precision-machined threads cut fluid leakage and avoids messy dripping at threaded joints.
• Heavy-Duty Brass ConstructionOur poppet style relief valve is fully forged from heavy solid brass. It resists rust, oxidation and medium erosion, maintaining stable sealing performance under long-term high-pressure working conditions far better than cheap alloy valves.
• Multi-Media Compatible Safety ValveThis adjustable relief valve works safely with compressed air, domestic water and hydraulic oil. It releases excess pressure automatically to protect pumps, compressors, boilers and hydraulic equipment from burst damage.
• All-Scenario Pipeline Protection ToolThe pressure control valve with 100-300 PSI wide range fits household water heaters, air compressors, industrial hydraulic machines and boiler systems, a necessary safety fitting to extend pipeline service life and cut breakdown risks.
