Gate Valve – KSD-UKG

From uni-directional, bi-directional, through-conduit, heavy duty or for use in slurry, these knife gate valves offer non-clogging shutoff on suspended solids in pulp and paper, power, wastewater treatment, and chemical industries.

In a unidirectional gate valve the medium can flow in only one direction.
Unidirectional knife gate valves only seal on one side.
They are suitable for water, paper and pulp slurries, mining, chemicals and some sticky slurries, fly ash, sugar mills and more.
The unidirectional knife gate valve can also be used in harsh, aggressive environments and high temperatures.
