Check-All Back Pressure Valve

The flange insert valves are the ultimate check valves in flanged systems. Check-All provides the simplest and most economical way to install a back pressure valve in a piping system. The valve body helps position itself while bolts are being installed and tightened. Two gaskets are required instead of the one normally used in a flanged joint. Check-All Back Pressure Valves are available in 150, 300, 600 ANSI with the option of 1- 40 psi. Certification is available for all Check-All Back Pressure Valve Models.
