HD1 DIAPHRAGM VALVE

The valve seat is excellent in airtightness by adopting PTFE diaphragm (membrane).

● It is possible to replace the diaphragm and automatic-driving part by removing the bolt/nut
   even in the piping condition. Inspection/maintenance is easy.
   Maintenance is easy.
● It is excellent in cleaning, since there is no pocket in the flow channel of the body.
● Because of the structure which does not use the gland packing, there is reliability against
   the leakage compared with the valve having the gland.
