Sliding Gate Valves utilize an ingenious sliding plate mechanism consisting of a fixed slotted plate seated in the body and a parallel moving slotted sliding disc driven by the stem. As the sliding plate moves across the stationary plate, the alignment of precision flow slots smoothly throttles or completely isolates fluid flow, delivering short stroke travel (typically only 6 to 9 mm), ultra-fast response times, and exceptional control precision without cavitation or turbulence.
Zeron Fastners manufactures Sliding Gate Control and Shutoff Valves in Carbon Steel and Stainless Steel (CF8M/316) in sizes 1/2" to 10". The non-turbulent straight-through slot design prevents wire-drawing and erosion, delivering exceptionally quiet, cavitation-resistant flow modulation across saturated steam lines, chemical batching, gas headers, and cooling circuits.
