It offers corrosion resistance with brass construction and a music wire spring, operates reliably up to 250°F, and delivers a high flow rate of 136 CFM. Certified with UV and NB marks, this valve ensures dependable pressure relief for industrial and home compressor systems. ## 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. ## Features - Relief pressure preset to 150 psi with flow rate of 136 cfm - 1/8 NPT threaded inlet connection with Vibra-Seal thread lock - Brass construction and music wire spring for corrosion resistance - 250 F maximum temperature for use in high temperature applications - ASME safety rated with UV and NB marks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0142AM5LU | | Best Sellers Rank | #435,441 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #578 in Relief Valves | | Brand Name | Control Devices | | Connector Type | Threaded | | Customer Reviews | 4.6 4.6 out of 5 stars (110) | | Exterior Finish | Stainless Steel,Steel,Zinc | | Included Components | Brass Safety Valve | | Inlet Connection Size | 0.13 inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 2 x 1 x 1 inches | | Manufacturer | Control Devices | | Manufacturer Part Number | ST2512-1A150 | | Material Type | Brass | | Maximum Pressure | 150 psi | | Model Number | ST2512-1A150 | | Number of Items | 1 | | Number of Pieces | 1 | | Number of Ports | 2 | | Outlet Connection Size | 2 inches | | Outlet Connection Type | MNPT | | Size | 1/8 Inch | | Thread Size | 1/8 inch | | Thread Type | NPT | | Unit Count | 1 Count | | Valve Type | Pressure Relief Valve | ## Product Details - **Brand:** Control Devices - **Exterior Finish:** Stainless Steel,Steel,Zinc - **Inlet Connection Size:** 0.13 inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 2 x 1 x 1 inches - **Material:** Brass - **Maximum Operating Pressure:** 150 psi - **Number of Ports:** 2 - **Outlet Connection Size:** 2 inches - **Outlet Connection Type:** MNPT ## Images ![Control Devices ST2512-1A150 ST Series Brass Soft Seat ASME Safety Valve, 150 psi Set Pressure, 1/8 Male NPT - Image 1](https://m.media-amazon.com/images/I/41CchFxBr5L.jpg) ![Control Devices ST2512-1A150 ST Series Brass Soft Seat ASME Safety Valve, 150 psi Set Pressure, 1/8 Male NPT - Image 2](https://m.media-amazon.com/images/I/61QQ2b02wqL.jpg) ## Frequently Bought Together - Control Devices ST2512-1A150 ST Series Brass Soft Seat ASME Safety Valve, 150 psi Set Pressure, 1/8 Male NPT - irhapsody Relay 200A, 12V Continuous Duty Relay, 4 Pin Starter Relay, Spst High Current High Power On/Off Control Relay, Split Charge Relay Switch - mankk Air Pressure Switch 70-100 PSI Thread 1/8"NPT 24V 12V DC Air Compressor Pressure Switch for Air Horn Train 70-100-1/8"NPT-BK --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/25295715-control-devices-st2512-1a150-st-series-brass-soft-seat-asme](https://www.desertcart.sg/products/25295715-control-devices-st2512-1a150-st-series-brass-soft-seat-asme) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-28*
