Operational principle:
3 ways by-pass valves allow to switch over from one relief valve system to another.
Also called “selector valves”, 3 ways by-pass valves are adapted to compulsory decompression system (rupture disc, safety valve) and other parallel strainer systems.
Advantages:
- Avoid all risk of production system shutdown. Our 3 ways by-pass valves design ensure that at least one pressure relief devices be open.
- Switch over one pipeline to another through one single operation and without using interlock
