Model: VK16
| Model | Nominal Diameter | Method | Maximum Operating Pressure | Maximum Operating Temperature | Body Material | Connection |

Features
Unlike general sight glasses, this sight glass is specifically designed to be installed on the inlet side of the trap.
With conventional sight glasses installed on the outlet side, you can only tell whether the trap is working or not.
However, this sight glass allows visual confirmation of steam leakage and condensate accumulation inside the trap, making it not only effective for energy-saving but also useful for monitoring equipment operation.By simply rotating the internal core, it can also be installed on vertical piping.
