The XD-HP series knife gate is a bi-directional high performance valve specially designed to withstand high pressures (PN10, PN16, PN25, PN40, PN64, PN100, PN160, PN250). Resilient seated valve with adjustable stuffing box mounted on top of the body valve, suitable to handle semi-solids, raw sewage, mud, dehydrated sludge and general industrial applications.

The design of the body and seat ensures a bubble-tight shutoff in both directions of the flow.
