High pressure knife gate valve type FH600

Uni-directional high pressure knife gate valve

High-pressure knife gate valve: unidirectional

The FH600 is a uni-directional high pressure knife gate valve in full flange design with bonnet. So this 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 in petro chemistry and waste water technology sectors.

The plate gaskets can be exchanged without big effort within a few minutes and also serve as flange gaskets. Like this, the maintenance work und the associated shutdown can be minimized extensively. The gaskets 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.
