## Product Features

### POINT Pressure Reducing Valve for Shaping That Uses Steam

It has specialized performance for reducing the steam pressure on the primary side to a shaping pressure and has a long track record of use.

### POINT Soft Valve Seat

The valve seat is made of the same PTFE containing carbon fiber that is used for the piston valves, so it has a high level of airtightness when closed and supports a high pressure reduction ratio.
