Diaphragm Valve V120, V130 series

The dispenser valves, Diaphragm Valves are designed to dispense low viscosity materials. Since the parts that are in contact with liquid are made of fluororesin, they have excellent chemical resistance. The diaphragm is used for the seal of the valve and this prevents the liquid from penetrating into the drive body. The light and compact design makes it easy for mounting flexibility and easy integration into automated machine or used with multiple connections. A stroke control adjustment which is the flow regulating screw makes it easy to fine tune shot sizes by controlling the opening and closing strokes of the valve.

  • Wide range of the seal body materials, such as PTFE, black polypropylene, black PTFE, SUS304, allows you to select the best valve suitable for the fluid to be dispensed.
  • Since the diaphragm is used for sealing, the fluid will not infiltrate into the drive part.
  • It is easy to integrate in the automated machine and use multiple installation system, since it is light and compact.
  • Trace volume dispensing can be done as the open-close stroke of the valve is controlled by fluid flow adjusting screw.
  • Common: Resist, Oil, Organic Solvent
  • V120-T: Anaerobic adhesive 
  • V130-P, V130-T: UV cure adhesive

Structure of the valve

V120/130 series valves regulate material discharge by opening and closing the flow path with a diaphragm in the middle of the material channel.

When the air pressure from the controller is not entering the valve, the diaphragm is closed by a spring.

When the air pressure from the controller enters the air import, the central part of the diaphragm is pulled up, opening the flow path and allowing material to flow.
