Plunger valve RIKO®

with handwheelflow controlpressure-control

Externally 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 With self-locking worm gear unit including position indicator 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
