0372271, 530C-STD, 1/2" x 3/4" Poppet Adjustable Relief Valve Pressure Relief Valve for Systems Containing Water, Oil, or Air, Used in Commercial, Residential and Industrial Applications

0372271, 530C-STD, 1/2" x 3/4" Poppet Adjustable Relief Valve Pressure Relief Valve for Systems Containing Water, Oil, or Air, Used in Commercial, Residential and Industrial Applications

• 【High-Quality Materials】1. 530C-STD 0372271 Reliable Brass Valve Body: Excellent corrosion resistance, good mechanical strength and machinability, and good compatibility with water, oil, and air. 2. Buna-N Seals: Excellent wear resistance and sealing performance, good oil and water resistance, good elasticity, and repeatable sealing. High-quality materials provide strong sealing performance, ensuring long-term use without failure. 3. Stainless Steel Spring: Corrosion-resistant and rust-proof, with excellent elasticity and fatigue life, capable of withstanding high pressure (up to 300 psi), and an adjustable pressure range of 50 to 175 psi (3.45 to 12.06 bar).
• 【Precision Parts】 The 0372271 530C 3/4" Calibrated Pressure Relief Valve consists of a bronze body structure, 3/4-inch NPT male inlet and 1/2-inch NPT female (drain) outlet connections, a stainless steel spring, a brass valve cover, a nitrile rubber valve disc, and a nitrile rubber O-ring. The poppet-type design provides quick response. Compared to traditional flap-type pressure relief valves, the poppet structure offers faster response and action speed, clear and precise pressure relief action, and reduced impact vibration. These features are very beneficial for systems requiring frequent opening and closing of the pressure relief valve.
• 【Wide Range of Compatible Media and Application Scenarios】 The 0372271 Poppet Adjustable Relief Valve can be used with media containing water, oil, or air. It is widely used in commercial, residential, and industrial applications, including water heaters, water pumps, boiler bypass pressure relief, and closed-loop water supply systems without expansion tanks. It prevents the main safety valve from malfunctioning and prevents equipment damage and pipe bursts due to excessive pressure. Warning: The 3/4 IN Brass Poppet Type Calibrated Pressure Relief Valve is not lead-free and should not be used with drinking water.
• 【Powerful Functions】0372271 - 3/4" 530C Poppet Style Relief Valve:1. Protects water systems from excessive pressure buildup: When the pressure in the pipeline exceeds the set value, the valve automatically opens to discharge some water, thereby reducing system pressure; 2. Addresses pressure increases caused by thermal expansion: When a water heater or heating device heats water, the water volume expands. This valve can relieve pressure when the set pressure is reached, preventing frequent opening or damage to the main safety valve or other components.
• 【Reliable After-Sales Service】Every 0372271 - 3/4" 530C Poppet Style Relief Valve undergoes rigorous pre-shipment testing, including adjustment accuracy checks, material strength evaluation, and NPT thread standard verification. We also provide a 1-year warranty. If you have any questions, please leave us a message – we will respond within 12 hours to help you quickly repair your equipment.
