1/4" NPT Pressure Relief Valve 304 Stainless Steel Adjustable Range 0-15PSI

About this item

• 【Superior 304 Stainless Steel Construction】Unlike brass valves that may contain lead or corrode, this pressure relief valve is machined from solid 304 stainless steel. This material provides excellent rust, oxidation, and chemical resistance for a longer service life in demanding conditions. Whether handling moist air, hydraulic fluids, or water systems, the robust body maintains integrity under high pressure. This makes it an ideal water pressure relief valve for plumbing and a durable air compressor pressure relief valve for workshops, ensuring your equipment stays protected.
• 【Precise 0-15 PSI Low-Pressure Adjustment Range】This pressure release valve is specifically engineered for low-pressure systems, offering a fine-tunable setting from 0 to 15 PSI. Unlike standard valves with broader ranges that sacrifice precision, this unit allows micro-adjustments to the activation threshold for ultra-sensitive applications. Simply turn the threaded knob on top to adjust the setting, giving you exact control over low-pressure air tanks, pneumatic actuators, or sensitive hydraulic equipment. Perfect for low-pressure pneumatic systems, light-duty compressors, and precision laboratory instruments requiring reliable low-pressure protection.
• 【Dual Function: Automatic Overpressure Protection & Manual Testing】This valve delivers two essential safety functions. First, as an automatic air compressor pressure relief valve, it opens instantly when pressure exceeds your preset limit, releasing the medium until pressure drops to a safe level and preventing bursts or equipment damage. Second, the top ring provides manual pressure relief, allowing you to easily check system pressure and test valve operation during routine maintenance. This ensures the mechanism stays clear of debris and works correctly, which is vital for critical safety systems.
• 【Premium EPDM Seal & CNC-Machined Threads for Zero Leaks】Leakage is the nemesis of any pressure relief valve, which is why we paired our stainless steel body with a high-grade EPDM seal. This synthetic rubber compound offers outstanding resistance to water, steam, and aging, with a wide operating temperature range from 122°F to 302°F (-40°C to 150°C) , ensuring stable sealing recovery and elasticity even after thousands of cycles. Complementing the seal are precision-cut 1/4" NPT threads manufactured using advanced CNC machining with strict tolerance control. This eliminates thread misalignment and, when paired with the included sealing tape, guarantees a perfectly leak-free installation.
• 【Compact Size with Universal 1/4" NPT Thread for Low-Pressure Systems】Designed for easy integration, this pressure release valve features a standard 1/4" male NPT thread. The compact form factor (Total Length: 2.77 inches; Body Length: 2.16 inches) fits tight spaces where bulkier valves cannot. It is ideal for low-pressure air compressors, pneumatic actuators, low-pressure water pumps, irrigation systems, and laboratory equipment. The precise threads ensure smooth engagement with standard female NPT ports, making this valve a reliable component in your low-pressure system for years.
