  • Actuators sized to prevent blocking
  • Piston plug designed to eliminate any risk of clogging
  • Long stroke for completely clearing the valve orifice
  • Powder flow facilitated by spherical bodies
  • Valve washing and rinsing optimised by adding a fractional changeover valve
  • Nitryl seal withstanding up to 100°C and particularly resistant to powder abrasion
