ports
WARNING
When stop valves are closed during service, the pressure
of the closed circuit will increase due to high ambient
temperature. Make sure the pressure is kept below the
design pressure.

▪ The gas and liquid stop valves are factory open.
▪ Make sure to keep all stop valves open during operation.

break the valve body.
