Diaphragm Dispensing Valve GV-525UP

GV-525UP is a diaphragm valve designed for precise flow control of low to medium viscosity materials such as anaerobics, cyanoacrylates or UV lacquers and much more.

GV-525UP with an internal spring return makes it fully adaptable for use with our time/ pressure controllers. The design of short opening stroke also make operation more easier and increase percision of dispensing.

Specially, the wetting part which directly contact with dispensing chemicals, have various options of material so that manufacturers could choose the most suitable one for their dispensing liquid (including: Teflon, PEEK or Acetal).

Features and benefits

  • Economical, Precision dispense, easily operate.
  • GV-525UP, Diaphragm Needle Valve is a kind of pneumatic valve.
