ENGINEERING DATA
The GCF-40 is a reverse flow check with all the characteristics of the G-40 check but designed for use with the 1" conventional casing flow valve. The valves are used to protect the
casing from backflow, allow for pressurizing the tubing in various procedures, and prevent any comingling of flow in dual installation. The conventional check assemblies utilize the
same metal to metal seal as well as metal dart to soft hy-car pad seal as does the retrievable valve checks. The GCF-40 check is a velocity type check requiring flow pressure to
force the dart on seat but is also available in a normally closed variation with a spring attachment.
