Crafted from corrosion-resistant brass and stainless steel, it operates reliably up to 251°F. ASME and National Board certified, it ensures top safety standards for home and light industrial air compressors, preventing overpressure with a leak-proof silicon seal. ## Description This Control Devices SV-120 ASME safety valve has a brass body, a 120 psi relief pressure, a 1/4" male NPT threaded inlet connection, and a stainless steel pull ring for manual pressure relief. The valve's brass body, brass valve seat, and the zinc plated steel spring resist corrosion and can be used in operating temperatures up to 250 degrees F. The preset relief pressure is accurate to within +/- 3 percent and a silicon O-ring provides a leak-proof seal to within +/- 10 percent of the relief pressure. This safety valve is American Society of Mechanical Engineers (ASME) safety rated and displays the UV mark for pressure vessel safety valves. It also displays the NB mark for certification in accordance with NB-501, National Board Certification of Pressure Relief Devices. This safety valve has a 47 Standard Cubic Feet per Minute (SCFM) flow rate and is suitable for low capacity pressure relief applications such as in home construction air compressors. Relief valves remove excess pressure or vacuum from a system. The valve openings allow fluids or gases to escape to decrease pressure, and then close once the valve reaches the reseating pressure limit. They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit. Some relief valves have an adjustment mechanism to set the pressure where the valve opens, making it suitable for various applications. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in which it operates. Relief valves are used in a variety of applications, such as air compressors, petrochemical and chemical manufacturing, natural gas processing, and power generation. Review: value for money - good quality Review: Seems good. - Replaced a leaking pressure relief valve. This was in the right pressure range and seems to be in the ballpark, though haven’t really tested it. Good so far, but haven’t had a runaway yet. ## Features - Relief pressure preset to 120 psi with flow rate of 47 SCFM - PLEASE NOTE: 1/4" MALE NPT THREADED INLET CONNECTION APPROX 0.54 INCHES OUTSIDE DIAMETER - Brass construction and stainless steel spring for corrosion resistance. The preset relief pressure is accurate to within +/- 3 percent and a silicon O-ring provides a leak-proof seal to within +/- 10 percent of the relief pressure. - 251 degrees F maximum temperature for use in high temperature applications - ASME safety rated with UV and NB marks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G2EO2YM | | Best Sellers Rank | #25,221 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #10 in Relief Valves | | Brand | ALL Tool Depot | | Brand Name | ALL Tool Depot | | Connector Type | Threaded | | Customer Reviews | 4.6 out of 5 stars 1,410 Reviews | | Exterior Finish | Stainless Steel , Zinc | | Inlet Connection Size | 0.25 inches | | Inlet Connection Type | threaded | | Item Dimensions | 2 x 0.5 x 0.5 inches | | Item dimensions L x W x H | 2 x 0.5 x 0.5 inches | | Manufacturer | All Tool Depot | | Manufacturer Part Number | SV-120 | | Material | Brass | | Material Type | Brass | | Maximum Pressure | 120 psi | | Model Number | AX-SV-SERIES | | Number of Ports | 2 | | Outlet Connection Size | 0.25 inches | | Outlet Connection Type | MNPT | | Size | SV-120 | | Specification Met | asme | | Thread Size | 1/4 inch | | Thread Type | NPT | | Unit Count | 1 Count | | Valve Type | Pressure Relief Valve | ## Product Details - **Material:** Brass - **Brand:** ALL Tool Depot - **Item dimensions L x W x H:** 0.5 x 2 x 0.5 inches - **Exterior Finish:** Stainless Steel,Zinc - **Inlet Connection Size:** 0.25 Inches - **Inlet Connection Type:** threaded - **Outlet Connection Type:** MNPT - **Maximum Operating Pressure:** 120 Pound per Square Inch - **Number of Ports:** 2 - **Outlet Connection Size:** 0.25 Inches ## Images ![New 1/4" NPT 120 PSI 47 SCFM Air Compressor Relief Pressure Safety Valve, Tank Pop Off - Image 1](https://m.media-amazon.com/images/I/51KFde9zGSL.jpg) ![New 1/4" NPT 120 PSI 47 SCFM Air Compressor Relief Pressure Safety Valve, Tank Pop Off - Image 2](https://m.media-amazon.com/images/I/51Q83o1Zd1L.jpg) ![New 1/4" NPT 120 PSI 47 SCFM Air Compressor Relief Pressure Safety Valve, Tank Pop Off - Image 3](https://m.media-amazon.com/images/I/81D1z0bVEzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ value for money *by R***N on May 1, 2026* good quality ### ⭐⭐⭐⭐⭐ Seems good. *by M***S on December 7, 2025* Replaced a leaking pressure relief valve.
