Item Number 150WCSSBR-2 1/2, Silent Wafer Check Valve - Steel/Stainless Steel On Colton Industries

Series '150WCS'

Available with cast steel or stainless steel body in sizes 2" to 12" with a body designed to fit between ANSI 150# and 300# flanges for maximum operating pressures as follows:
PMO: (Maximum Operating Pressure)
2" to 4" 720 psi @ 100 deg. F
640 psi @ 250 deg. F.
5" to 12" 275 psi @ 100 deg. F.
245 psi @ 250 deg. F.

Notes:

These valves are designed for horizontal and vertical flows.
The conical spring design allows the plug greater travel, resulting in better flow characteristics than valves of conventional design.
These valves can be machined to accept an optional soft seat (usually Buna-N) for bubble tight shut-off.
