VAG RIKO® Plunger Valve

True multi-talents
Our RIKO^® Plunger Valves are true multi-talents. A sophisticated technology makes these valves control professionals in almost any application. They come with a one-piece, streamlined body for regulation of large amounts of water safely and reliably.

Product features

• Cavitation-free operation provided by optimal design.
• Valve seal in the no-flow zone for a long service life.
• Drive with a self-locking worm gear unit with a constant transmission ratio for a linear control curve in connection with an optimal control device.
• One piece, compact body across the full nominal width, thus reducing the number of components and eliminating potential leak path.
• Hard-faced bronze guides for low operating forces which also prevent the piston from jamming.
• Quad-ring seal not sensitive to deposits on the piston.
• Valve highly efficient thanks to an optimised design and flow path.
• Connecting rod installed in maintenance-free, robust bronze / plastic compound bushes.
