The OPD valves will not pass LP unless a hose is hooked up- you can open the valve, and nothing will come out. The pigtails have collars that melt at a low temperature, which allow the pigtail end to pull out, shutting the flow in case of fire. The other check valves are in the pigtail- they are excess flow valves, which will shut the flow in case of a line break- they will also shut off if the valve is opened to quickly. To reset these, the valves must be shut, hoses disconnected to equalize all pressures.
