Brass Ball Check Valve, 1/4 NPT Male

The Control Devices ball-type check valve is a versatile component that offers tight sealing and can be utilized as a tank check valve for small compressors or as a part of pneumatic circuits. Constructed with a brass body, the valve exhibits excellent corrosion resistance, ductility at high temperatures, and low magnetic permeability, making it compatible with a wide range of materials, including copper, brass, plastic, aluminum, and welded steel. The incorporation of fluorocarbon O-rings further enhances the valve's resistance to high temperatures and chemical exposure.

One of the key features of this check valve is its threaded connection design. It features female National Pipe Taper (NPT) threads on one end and male NPT threads on the other, allowing for seamless integration with both male and female threaded pipes. The NPT threads provide a tighter seal compared to straight threads, ensuring a more secure and reliable connection.

The Control Devices ball-type check valve is rated for a maximum pressure of 250 pounds per square inch (psi) and a maximum working temperature of 250 degrees Fahrenheit. These specifications make it suitable for a variety of applications, including water, gas, air, and steam lines.

Check valves, in general, serve the purpose of restricting the flow of fluids and other loose materials through a pipe or passageway to a single direction. The flow enters through one port and exits through the other, with the valve closing when the 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 in the forward direction, while a swing check valve has a movable disc on a hinge to block reverse flow.

Control Devices, the manufacturer of this ball-type check valve, is a company founded in 1963 and headquartered in Fenton, Michigan. The company is known for producing specialty valves, nozzles, and condensate traps, and it meets the ASME (American Society of Mechanical Engineers) standards, ensuring the quality and reliability of its products.

In summary, the Control Devices ball-type check valve is a versatile and high-performance component that offers tight sealing, corrosion resistance, and compatibility with a variety of materials and applications. Its unique threaded connection design, combined with its pressure and temperature ratings, make it a valuable asset in various fluid and gas handling systems.
