High pressure knife gate valve type FH650

Bi-directional high pressure knife gate valve

High pressure knife gate valve

Our FH650 is a bi-directional high pressure knife gate valve with full flange design and bonnet. So this knife gate valve is also applicable at high pressure stages up to PN100 and guarantees absolute leak-tightness. Its feature to regulate dangerous mediums at high pressure ranges made it a standard gate valve into petro chemistry and sewage technology sectors. The gate seats can be exchanged without big effort within a few minutes and also serve as flanges gaskets. Like this the maintenance work and the associated shutdown can be minimized extensively. The gate seats can be protected from early abrasion by a deflecting cone (from PN40 without any extra charge). The different sizes, pressure stages, materials and drives are shown on the datasheet, which you can download on our website. For special executions please contact our sales department.
