VAG RIKO® Plunger Valve with own-medium control as pressure reducing valve

PN: 10/16 - DN: 150...1000

Productgroup: Control Valves

Medium: Water

Own-medium controlled control valve with annular flow cross-section for the continuous regulation of high pressure differences and flow rates. Long service life as the bearings do not come into contact with the medium. Wear-resistant, corrosion- and infiltration-proof guide rails due to hard-facing. This ensures low operating forces and prevents jamming of the piston. Suitable for use in water treatment, water distribution, in dams, power plants, industry and in pressure management.

  • Face-to-face length: acc. to EN 558, basic series 15 - from DN 500 1.5 x DN
  • With flange ends on both sides acc. to EN 1092-2
  • Control valve in straightway type
  • With customized control device depending on operating conditions
  • Low actuating torque due to pressure balanced valve piston
  • Rotationally symmetrical flow guidance
  • Annular flow cross section in each position
  • Axial movement of the plunger by means of crank gear mechanism
  • Elastic profile sealing ring located in the no-flow zone for high durability
  • Wear-resistant, corrosion-resistant and infiltration-proof piston guides in the body by micro-finished bronze weld overlay
  • Regulation is effected by own-medium controlled operation; the pressure difference of the medium generates the torque necessary for operation (the pressure difference must be at least 2 bar)
  • Independent of the inlet pressure / flow fluctuations the valve regulates a higher inlet pressure down to a constant, lower outlet pressure
  • Weight lever with double bearing, prevents the transmission of drop-weight forces to the valve bearing
  • Drop weights in modular design for customised adaptation to operating conditions
  • Body: Ductile iron EN-GJS-400-15 (GGG-40)
  • Piston: Stainless steel 1.4301
  • Valve sealing: EPDM
  • Inner parts: Stainless steel
  • Actuator::
    • Cylinder: stainless steel, guides made of bronze
    • Drop weight, bracket, lever: SJ235
    • Bearing bolts, bolts: Stainless steel 1.4021
    • Lever bearing: 1.4305 and/or bronze and PTFE
