Epoxy paiting suitable for drinking water applications.
The knife gate valves are manufactured with body in cast iron and knife if stainless steel AISI 304. Designed as wafer concentric type, these knife gate valves can be installed in any position, but follow the flow direction in one way only. The knife gate valves grant full passage of the fluid, no pressure drops and are suitable for thick fluids. Standard execution by handwheel, pneumatic operator or electric actuator on demand.
