Diverter Valves - 3, 4, 5, and multi-way switching valve designs
SchuF designs and manufactures advanced dead and slow space free diverter valves for switching critical processes and difficult media. They are often refered to as Switching valves, multiport and multiway valves.

Industries using Multiway Valves
Many of our multiport diverter valves are designed for critical processes and are ideal for severe applications. They are widely used in the PTA, Petrochemical, Polymer & Plastics, as well as Refinery industries. They are particularly suited to applications with highly viscous media or processes that have to continuously back flush their process lines.
Switching Valve Applications
They are mostly used to split or combine process flows or to switch medium between alternative pieces of process equipment such as pumps, filters, or complete pipelines. With control functionality on one or more outlets constant flow to sensitive parts such as spinning heads can be maintained by varying flow to less sensitve parts such as dye heads.
They function in severe operating conditions with high flow rates, high pressure or temperature variants, and in vacuum conditions. In the refinery, diverter valves have been installed in vacuum distillation units (VDU) at the bottom of vacuum towers. The highly viscous vacuum residue can clog ball valves and t-pieces and typically requires the lines to be constantly back flushed.

5 Way Diverter Valve 7 way Multiport Diverter Valve
The SchuF dead space free VDU Diverter valve does not allow the valuable effulent to stick in the valve and simultaneously offer the ability to route the media to intermediate storage tanks, to the FCCU or hydrotreating processes or a combination of all three or more.
