## Overview

The Control Devices ST2512-1A150 is a premium brass soft seat safety valve engineered for precise pressure relief at 150 psi. Featuring a corrosion-resistant brass body, a 1/8 inch male NPT threaded inlet with Vibra-Seal thread lock, and a robust music wire spring, it operates reliably up to 250°F. Certified by ASME with UV and NB marks, this valve delivers a high flow rate of 136 CFM and leak-proof performance, making it ideal for industrial compressors and high-temperature applications.

## Description

This Control Devices ST2512-1A150 ASME safety valve has a brass body, a 150 psi relief pressure, a 1/8 inch 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 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 136.3923 cubic feet per minute (CFM) flow rate and is suitable for pressure relief applications such as in home construction or industrial air compressors.

Review: Great product - Arrived quickly, good quality. Works like it should. Would reccomend to anyone needing one. I bought it for my train horns on my truck. I did not want to be that guy driving down the road and the compressor fails and overloads the tank and i go air born.
Review: Nice quality - Easy replacement and great quality.
