Shut out the leak
The DV series uses a diaphragm to open and close the valve, so different from other valves, there is no leak from the shaft sliding part.- Easy maintenance
The simple structure of only the valve (SCS-13) and the diaphragm enables easy maintenance by removing the bonnet. - Fits as valve for piping
It can be used not only for vacuum but also for fluid. Also, various materials for corrosion resistance can be coated(surface treatment).
