KSB - Model ISORIA 10/16 -Elastomer-lined Butterfly Valve
The ISORIA 10/16 elastomer-lined butterfly valve utilizes a fully elastomer lined body, centered shaft design, in the 1 1/2 to 40 inch size range. ISORIA 10/16 Valves are designed for the multitude of moderately corrosive applications throughout the industry. The ISORIA 10/16 valve uses a spherically machined disc and a one-piece body that is totally isolated from the flowing media by means of the inner elastomer lining. A strong shaft-disc connection is provided by an exclusive splined shaft arrangement for precise positioning and reliable operation.
The ISORIA 10/16 valve is used in non-corrosive and moderately corrosive applications such as 50% caustic soda, 98% sulfuric acid, seawater, cooling water, river water, de-mineralized water, utility services, hydrogen gas, brown pulp stock, weak black liquor, white liquor, high chloride content limestone slurry in FGD (flue gas de-sulfurization), and others.
The ISORIA 10/16 valve utilizes an elastomer liner and either a metal or coated metal disc to withstand moderate corrosion and/or abrasion. With a spherically machined disc and matching liner, this valve provides tight shut off both upstream / downstream and from leakage into the shaft areas. The unique liner design allows a lug body, semi-lug, and flanged valve to be used under full rated pressure with the downstream flange removed. Shaft sealing is accomplished by using a spherically machined disc, mated to a spherically molded liner (in the hub area). The elastomer liner is also designed to provide additional compression down onto the disc hubs and down onto the shafts. A dry body and a dry shaft disc connection design are used throughout the product range.
Key benefits of the ISORIA 10/16 valve include:
