Knife edge gate valve

Microfinish Knife gate valves are primarily made for isolation and on-off services in systems with high suspended particle contents. Knife gate valves are particularly useful for managing viscous, corrosive, abrasive media, semi-solids, dry ash, chips in addition to the slurry and other application across industries such as mining, pulp and paper, general industrial, energy, waste water management, minerals and metals, steel plants, thermal power plants and chemical/ petrochemical industries and Oil & Gas. It works by enabling unhindered, easy passage of thick media over soft seals.
We use high grade raw material and cutting edge technology in adherence to the international quality standards. These valves are designed by skilled professionals in conformation with international standards.
