Our Jash mono series of knife gate valves incorporate an innovative circular knife gate that is precision machined around the complete circumference. This means that it cuts through solids when opening AND closing.
The global pulp and paper industry produces almost 380 million tons of paper and board annually. Valves used in the process bring their own special challenges for low and high density mediums. Our ‘O’ ring shaft seal is protected by two brass scrapper rings to eliminate damage to the sealing system by solids or other toxic media. The gate remains within the valve housing (bonnet) when fully opened, eliminating leakage of slurries, gases or chemicals to atmosphere.
