From the product description, check product page for current description, price and availability:
- Relief pressure adjustable from 0 to 100 psi

- 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
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.
This valve is the heart of my Spunding Valve Build. It is a manually adjustable pressure relief valve. Adjustable from 0 to 100 PSI. I’ve found the pressure markings on this to be difficult to use/possibly inaccurate. My Spunding Build accounts for this via a pressure gauge. There is no homebrewing-related situation I’m aware of that would have you at 100 PSI. Generally you’d be at or below 30 PSI. As always, you’ll want to ensure that all components in your system (kegs, tubing, etc) are rated for your desired pressure.
