Features
- You do not need to consider back pressure and drain temperature as reliable functions.
- There is no steam loss because a water seal is formed.
- The valve seat unit is a complete spherical or hemispherical body, which provides excellent sealing and durability.
- Operates even when the back pressure is almost 100% of the inlet pressure.
