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

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

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

Product request

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
Internally and externally epoxy coated

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
