Relief pressure adjustable from 25 to 200 psi
1/4" male NPT threaded inlet connection
Brass construction and stainless steel spring for corrosion resistance
250 degrees F maximum temperature for use in high temperature applications
Silicon O-ring provides leak-proof seal to within 10 percent of set pressure
This Control Devices NC25-1UK002 safety valve has a brass body, an adjustable relief pressure, a 1/4" male NPT threaded inlet connection, a silicon O-ring, and a stainless steel pull ring for manual pressure relief. The valve's brass body, brass valve seat, and the stainless steel spring and ball resist corrosion and can be used in operating temperatures up to 250 degrees F. The valve can be adjusted to open between 25 and 200 psi using the knurled adjustment screw and locking jam nut. This safety valve has an 80 standard cubic feet per minute (SCFM) flow rate and is suitable for high temperature pressure relief applications such as in 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.
