Check valves are used in line with many spray nozzles when the application requires the complete shut-off of flow while maintaining full line pressure. The spring loaded ball-type design provides a drip-free seal with shut-off pressures of 5, 10 and 20 psi.
The unit consists of a two-piece body, an internal spring and a shut-off stainless steel ball. Available in 1/8”, 1/4”, 3/8” and 1/2” NPT sizes.
Flanges are made of 304SS
