Pipe o-ring check valves provide high quality directional

Pipe o-ring check valves provide high quality directional flow control and bubble tight shutoff for liquids and gases. These check valves are not to be used as a relief device. The opening pressure of the o-ring check valves is approximately 10 psi.
Pipe ball check valves prevent reverse flow where bubble tight shut off is not mandatory. These check valves are designed to operate to 660°F. These check valves are not to be used as a relief device. The opening pressure of the pipe ball check valves is approximately 10 psi.
This design increases the stainless steel filter area as much as 6 times the area of the disc type filter, and will permit higher flow rates with a lower pressure drop, and longer intervals between element changes.
