Abstract (en)
[origin: WO2023031812A1] The present disclosure relates to slide valves, in particular to a valve gate. The present disclosure relates to a valve gate for a slide valve comprising a ductile cast iron core (4) having two lateral protrusions (4A), said core being coated with a first polymer material (3) and two guides (1) made of a second polymer material, each fitted over a respective coated lateral protrusion, for sliding in grooves of the valve as the gate slides between an open position and a closed position of the valve; wherein the second polymer material is harder than the first polymer material.
