Incorporated Since 1992, SUPER VALVE MFG.CO. fulfilling the requirement of IS/BS standard industrial valves. We an ISO 9001 – 2015 Company has adopted the latest technology for manufacturing of valve and possess 3 (three) manufacturing units with all modern facilities for machining & testing (raw materials & finish product).
Knife gate valves are designed mainly for on-off and isolation services in systems with high content of suspended solids. The knife gate valves are especially beneficial for handling slurry, viscous, corrosive and abrasive media. The valves have a minimized pressure drop in fully open position, they are easy to actuate, they have a relatively low weight and are cost effective. Knife gate valves are designed to work in some of the most harsh environments, typically having a sharpened blade to cut through heavy liquids. They are especially useful in wastewater applications where corrosion is an important issue. So, in addition to the valve design optimized for slurry media, it is beneficial to have a knife made of acid-proof stainless steel as this makes it less susceptible to damages caused by corrosion and as a consequence it needs less frequent maintenance or even replacement. Knife gate valves should only be used for applications requiring a completely open or completely closed position and should not be used to regulate flow unless they are designed for it. Whenever fluid is forced against a partially closed gate, there will be a vibration, gradually eroding the disc and seat. In addition, the knife gate valves are designed to slowly open and close to safeguard against the impacts of water hammer.
