Soft Seat Knife Gate Valve Manufacturer In India
A Soft Seat Knife gate Valve is a very efficient flow-control device, which is used in situations where tight closing is needed, smooth operation and performance over low- to medium pressure media. In contrast to metal-seated models, soft-seated knife gate valves have elastomer or polymer-based seating materials like EPDM, NBR, PTFE or polyurethane. These soft seats are very good sealants hence employed well in industries that require zero leakage and soft handling of fluid. The greatest benefit of a soft seat knife gate valve is that it forms bubble-tight shut off, at low operating torque conditions. The material of the flexible seat can be compressed on the gate so that it forms a secure and leak free closure. This renders the valve highly appropriate in the treatment of water, sewage, and light slurries, food grade products, chemicals and other non-abrasive media. Its design reduces wear, friction and has smooth movement of the gates; hence, it has a long service life, and low maintenance expectations.
Depending on the application, soft seat knife gate valve bodies are usually composed of a stainless steel, ductile iron or cast iron. The cushioning seat lining is cushionable and can be changed easily with a cost effective maintenance and longevity. They are also beneficial in areas where it is necessary that contamination should be avoided as the soft seal provides clean sealing without ruining the media or the gate. The water treatment plants, paper and pulp mills, chemical industries, pharmaceutical processing, and food and beverage operations are some of the other industries that prefer to use soft seat knife gate valves due to their reliable operation and ability to seal. They come in different sizes and can either be manually or automated with the use of pneumatic, hydraulic, or electric actuators. In general, the Soft Seat Knife gate Valve has very high sealing efficiency, easy maintenance, and predictable operation in low to medium pressure operation. Its fluid seat design and ease of use make it an all time favorite among industries looking to have reliable, leak free and cost effective flow control.
