## Product Features

### POINT Easy Valve Replacement

Conventional flanged valves require two gaskets, eight sets of nuts and bolts, and piping alignment, making them difficult to install and remove. 2-way panel valves, on the other hand, can be easily replaced with one person regardless of valve size because they are only fixed with a stud bolt and two nuts.

### POINT Same Basic Structure as TPC

Since it is primarily TPC parts that are used, the stock of consumables and common parts can be reduced.
