Designed for reliable leak-proof performance with a silicon O-ring seal, it supports up to 6 SCFM flow rate, making it perfect for low flow pressure relief applications like tankless air compressors and industrial systems. ## Description This Control Devices CR25-100 pressure relief valve has a brass body, an adjustable relief pressure, a 1/4" male NPT threaded inlet connection, and a fluorocarbon O-ring. The valve's brass body, brass valve seat, and the stainless steel poppet resist corrosion and can be used in operating temperatures up to 250 degrees F. The valve can be adjusted to open between 0 and 100 psi using the micrometer-style nylon knob. This safety valve has an 6 standard cubic feet per minute (SCFM) flow rate and is suitable for low flow pressure relief applications such as in tankless 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.Control Devices manufactures valves and other flow control devices. The company, founded in 1963, is headquartered in Fenton, MO. ## Features - Relief pressure adjustable from 0 to 100 psi - 1/4" male NPT threaded inlet connection - Brass construction and stainless steel spring for corrosion resistance - Silicon O-ring provides leak-proof seal to within 10 percent of set pressure - Micrometer-style nylon knob for pressure relief adjustment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007GDY3CU | | Brand Name | Control Devices | | Connector Type | Threaded | | Exterior Finish | Brass, Stainless Steel | | Included Components | Brass | | Inlet Connection Size | 0.25 Inches | | Inlet Connection Type | National Pipe Tapered | | Manufacturer | Control Devices | | Manufacturer Part Number | CR25-100 | | Material Type | Brass | | Maximum Pressure | 100 Pound per Square Inch | | Model Number | CR25-100 | | Number of Ports | 1 | | Outlet Connection Size | 0.25 Inches | | Outlet Connection Type | MNPT | | Set Name | 0-100 psi | | Size | 0.25 Inch | | Specification Met | UL, ULC | | Thread Size | 0.25 inches | | Thread Type | Tapered | | UPC | 372657518635 | | Unit Count | 1.0 Count | | Valve Type | Pressure Relief Valve | ## Product Details - **Brand:** Control Devices - **Exterior finish:** Brass, Stainless Steel - **Inlet connection size:** 0.25 Inches - **Inlet connection type:** National Pipe Tapered - **Material:** Brass ## Images ![Control Devices - CR25-100 -CR25 CR Series Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4" Male NPT - Image 1](https://m.media-amazon.com/images/I/713OhItuiqL.jpg) ![Control Devices - CR25-100 -CR25 CR Series Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4" Male NPT - Image 2](https://m.media-amazon.com/images/I/71zWihqvH-L.jpg) ## Questions & Answers **Q: Anyone else have the problem where it releases all the pressure instead of resealing?** A: Reseating is not an issue for me, but setting a reasonably accurate and consistent pressure is a problem. The release pressure varies significantly (when used as a pressure relief valve for tyre inflation). **Q: Anyone had issues where it vents no matter what the pressure is set at? I'm testing it for a spunding valve with an inlet pressure of 15psi** A: I just got one to to make a spunding valve for beer. Mine leaks a little at all pressures. I connected to a keg and my gauge was reading 15 PSI. It gradually lost pressure. Gas coming out the small holes. I suspect I will have to return this one and hope the next one works. **Q: How does this work in the 2-4 PSI range?** A: Not great I think you better off getting something with narrower range device like 0-10 psi **Q: Is the reseat pressure adjustable on this as well, I'm needing it to crack at 100psi and reseat at 85-90psi, No lower. other don't reseat till 60psi** A: The reseat is not adjustable. It will reseat on its on around those pressures but it is not a controllable parameter. ## Frequently Bought Together - Control Devices - CR25-100 -CR25 CR Series Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4" Male NPT - Winters 2 inch Dial Size, Multi Function Economy Utility Dry Pressure Gauge, Brass Internals, Black Steel Case, Dual Scale 0-100 psi/kPa, 3-2-3% Accuracy, 1/4 inch NPT Bottom Mount, Pressure Gauge - Anderson Metals 56101-04 Brass Pipe Fitting, Barstock Tee, 1/4" x 1/4" x 1/4" NPT Female Pipe --- ## 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.tn/products/310468090-control-devices-cr25-100-cr25-cr-series-brass-pressure-relief](https://www.desertcart.tn/products/310468090-control-devices-cr25-100-cr25-cr-series-brass-pressure-relief) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
