M/C MS5001 Mark5, We are facing offenly LFO check valve leak due to the O-rings - at present we are using 435 VITON 70 SHORE TYPE A 30 O-RINGS, i would like to have any suggestion to recover this problem???

We don't know how old your machine is or how old the check valves are.

Leaky check valves have been a huge problem for GE-design heavy duty gas turbines. GE has tried many different check valves over the years, and the newer check valves have been steadily improving the situation.

We also don't know what kind of liquid fuel you are burning, and whether or not these o-rings are suitable for the fuel being burned. (There are a lot of different liquid fuels, including distillates, being burned around the world these days and some operators are just switching fuels without taking into account the entire system.)

I would suggest you contact your OEM packager or GE for assistance with determining proper check valves and internals for your specific application.
