Line shut-off valves are used to cut the flow in the line in case of any malfunction in the system or in case of emergency.
These valves can be manufactured in different combinations with the relief valves used to discharge the air, water and steam accumulated in the system together with the line shut-off valves:
• Air release valves located on both sides of the line shut-off valve
• Water and steam release valves located on both sides of the line shut-off valve
• Air release valves located on one side of the line shut-off valve and water and steam release valves located on the other side.
