V351 Valve Series (Pneumatic Diaphragm Valve)

Since the needle valve seals near the material out port, there is little liquid accumulation and liquid drainage is good.

Since the wetted part and the drive part are separated by a diaphragm and a needle valve with high sealing, it can be used for a wide range of liquid materials such as materials with fillers.

Several types of valves are available depending on the size of the material supply port and orifice diameter. 

In addition, it can be used in a form that suits the application by changing the incorporation direction of the liquid-in-pipe/port position, air-in position, and lock screw position.

*It is also possible to change to a double-acting type.

  • The diaphragm structure prevents liquid material from entering the drive part from the wetted part.
    • Opening adjustment is easy to fine-tune and fix settings with a scale and lock mechanism.
    • The needle adapter is a bag nut type, and the bending needle etc. can be easily adjusted in direction.
