MAXIMATOR
ball check valves prevent reverse flow where bubble tight shutoff is
not mandatory. These check valves are designed with a ball cradled
floating poppet to assure positive inline seating. This poppet design
allows full flow around the ball to minimize pressure drop. Check
valves are rated to 660°F. All check valves are supplied with glands
and collars. These check valves are not to be used as a relief device.
Materials.
Body, cover, poppet, cover gland: 316 series stainless steel
Ball and spring: 300 series stainless steel
