The 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 suitable to handle semi-solids, raw sewage, mud, dehydrated sludge and general industrial applications.

General Features

• 100% tight in both directions
• Two split body arrangements
• U-seat with a steel stiff core vulcanized, fixed between the two bodies by screws.
• Adjustable external stuffing box, allowing upper sealing replacement without valve disassembling from the pipeline
