Control Devices Brass Ball Check Valve, 1/4" NPT Female x NPT Male

Model: P2525-1WA   |    Mpn: P2525-1WA   |    PartNumber: P2525-1WA   |   Asin: B007GDXA60

The Control Devices ball-type check valve provides tight sealing, and can be used as a tank check valve for small compressors or as a component in pneumatic circuits. The valve body is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. Fluorocarbon O-rings provide higher temperature and chemical resistance. It has female National Pipe Taper (NPT) threads on one end and male NPT threads on the other for connecting a male and a female threaded pipe. The NPT threads create a tighter seal than straight threads. The maximum pressure rating is 250 pounds per square inch (psi), and the maximum temperature is 250 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.

Features

  • Can be used as a tank check valve for small compressors or as a component in pneumatic circuits
  • Brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability
  • Fluorocarbon O-rings for higher temperature and chemical resistance
  • Female and male NPT threads for connecting pipes with different ends
  • Maximum pressure rating of 250 psi and maximum working temperature of 250 degrees Fahrenheit

Valterra 200-C15W PVC Swing (No Spring) Check Valve, Clear, 1-1/2" Slip

Model: 200-C15W   |    Mpn: 200-C15W   |    Ean: 0019079201560   |    PartNumber: 200-C15W   |   Asin: B0064TQ2WQ

This Valterra 200-C15W check valve is made of clear schedule 40 (standard wall) PVC for corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC (polyvinyl chloride) pipes and fittings or can be connected to other materials such as steel, copper, or cast iron using transition fittings. Its full flow design allows for insignificant flow loss at the swing check, so no spring is needed. It has 1-1/2" slip connectors at both ends to connect to pipes with a smooth bore for enhanced flow and has a maximum pressure rating of 150 psi. This check valve meets ASTM International and American National Standards Institute (ANSI) standards and is suitable for use with landscape and irrigation, pool and spa, aquaculture, and general purpose applications.

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.

Valterra 200-C05F PVC Swing/Spring Combination Check Valve, Clear, 1/2" FPT

Model: 200-C05F   |    Mpn: 200-C05F   |    Ean: 0019079700452   |    PartNumber: 200-C05F   |   Asin: B00B95U5NW

This Valterra 200-C05F check valve is made of clear schedule 40 PVC (polyvinyl chloride) for strength and resistance to corrosion and mild chemicals. Its EPDM (ethylene propylene diene monomer) seal resists degradation caused by water and oils, and the swing/spring construction of this valve makes it possible to install it in any position. It has a 1/2" female National Pipe Taper (NPT) threaded connection at each end, a maximum pressure rating of 150 pounds per square inch (psi), and a spring tension of 1/2 lb. This check valve is suitable for use with landscape and irrigation, pool and spa, aquaculture, and general purpose applications.

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.

Valterra Products manufactures and distributes valves, hoses, sewer systems, and pool and spa products. The company, founded in 1981, is headquartered in Mission Hills, CA.
