About Control Devices Cast Brass Check Valve, 1-1/4" NPT
This Control Devices check valve is designed for installation into air compressor discharge lines. The valve body is made of cast brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. This valve has a glass-filled polytetrafluoroethylene (PTFE) poppet with eight discharge holes for quiet operation, and stainless steel spring. It has female NPT threads for connecting to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 250 pounds per square inch (psi), and the maximum working temperature is 450 degrees Fahrenheit. Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines. Control Devices manufactures specialty valves, nozzles, and condensate traps. The company, founded in 1963 and headquartered in Fenton, MI, meets ASME standards.
