Swagelok SS-RL3M4-F4 Relief Valve With Set 125.2PSIG 316SS NSMP

Swagelok SS-RL3M4-F4 is a stainless steel low-pressure proportional relief valve that protects hydraulic or pneumatic circuits from overpressure in compact installations. The valve features a 316 stainless steel body with end connections of 1/4 in MNPT on the inlet and 1/4 in FNPT on the outlet, aligning with Swagelok's RL3 series design. It is set to relieve at 125.2 PSIG, providing a precise, repeatable threshold to guard downstream equipment and piping. As part of the RL3 family, the valve employs proportional relief characteristics to respond to rising pressure and maintain stable relief performance across operating conditions. The 316 stainless steel construction offers corrosion resistance and compatibility with a broad range of clean media, making it suitable for instrumentation lines, sampling systems, and other low-pressure applications where a robust stainless solution is required. When selecting this valve, verify end-connection compatibility with your piping, ensure the set pressure aligns with system requirements, and confirm material compatibility with the media in your process.
