Valve gate systems – Perfect appearance, high process reliability

POLYFLOW Valve Gate systems are built with adjustable valve pin feature. All valve gate nozzle is equipped with a pre-centered pin guide and tight cylindrical fit that makes almost invisible gate marks and helps reduce wear on the valve pin. High visual requirements, various applications, reductions in cycle time, minimal shear stress.

Advantages:

  • Polyflow valve gate systems are built with an adjustable valve pin feature. The depth of valve pin is adjustable within 0.05mm accuracy.
  • All valve gate nozzle is equipped with a pre-centered pin guide and tight cylindrical fit
  • Pneumatic or Hydraulic dual drive cylinder design.
  • Easily adjust the depth of the valve pin on outside, no need to disassemble the piston.
  • Interchangeable valve pin and guide.

Single valve gate nozzles

POLYFLOW Single Valve Gate Nozzle has been designed with the latest piston technology and integrated with valve gate nozzle.
