Ball Valves Cannot be used in conjunction with corrosion resistant piping applications. Hence, depending on your application, it need not be opened more than 60 or 70 angular degrees from its closed position. A Lug-style valve is a versatile solution for chemical handling that can withstand high temperatures of up to 200 C. Either way, this type of valve is easy to handle and is more affordable than other types of valves. For duplex stainless steels, there is a balanced structure between the FCC and BCC arrangement of material component. 60 0 obj <>stream The combination of these feature make this series of valves and excellent and ideal choice for applications in aggressive atmospheres and harsh wash down situations - often incurred in food plants. (Online Form), New! Again, these types of valves can be automatically or semi-automatically operated. The Stainless Steel 304 body butterfly valves are less resistant to corrosion but have good strength. These valves are designed for a unidirectional flow of fluids inside the pipelines. n`` C;b >f(&rGDIh3jjjAJzvB Generally, there are three designs for offset designs available: Concentric disk valves have their seals line against the edge of the elastomer lining which ensures tight shut-off. So during plastic deformation at freezing temperatures, the FCC structure presents the material with a suitable amount of ductility and toughness for cryogenic applications. This material is covered by ASTM A216 standard (WCA, WCB, WCC), ASTM A352 LCB/LCC and ASTM A351 CF8/CF8M. Nickel helps in maintaining a face-centered cubic (FCC) structure in stainless steel at very low temperatures preventing unwanted transformation to body centered cubic (BCC) arrangement. End-connection type: wafer, lug, flanged or double flanged, butt weld; Seat material: soft (Teflon) or metal-to-metal (SS316 and Inconel); Eccentricity or offset design: centric or zero, double offset or double eccentric, triple offset or triple eccentric; Body and disc materials (Carbon steel, stainless steel, titanium alloy, nickel alloy, aluminum bronze); Mode of operation or actuation: electric, pneumatic, hydraulic, manual. Stainless steel butterfly valves specialize in corrosive piping applications. This is true especially when its function is to handle large amounts of liquids or gases at low pressure differentials, such as in a hydroelectric power plant MIV system. In the second offset, the shaft axis goes off the center of the pipe. /Type/ExtGState

Fusible Link Valves There are three offsets for triple offset butterfly vavles all mounted eccentrically. Concentric Disk butterfly valve are suitably designed with the following points: The Double Offset or Double Eccentric Valve is a high performance butterfly valve which is designed with two offsets of the stem. Butterfly valves API 609 can be classified according to their offset design. This may be dependent on the amount of torque needed to open and close the valve or the speed at which it must operate. Pneumatic Butterfly valves are typically used for transferring compressed and pressurized air. They are used in specific applications that require extreme resistance to fluid impact and high and low temperatures. Basically, austenitic stainless steel valves are used for low temperature applications such as in cryogenic processes. It then closes when the downstream pipe needs to be bled. Automated Valve Packages There is also a limit switch that controls the automatic operation of the valve: Pneumatic actuators are used to operate these types of valves for shut-off pipelines. With the triple offset design, sliding between the seat and disk can be eliminated.
