SVF SB79 Series Hastelloy Ball Valve

Central States Industrial (CSI) offers SVF's SB79 Series ball valve in Hastelloy®, providing superior corrosion resistance along with SVF's sanitary three-piece ball valve design. CleanFLOW™ SB79 ball valves are engineered to be a true process piping component to specifically meet the demanding processes found in the pharmaceutical industry, as well as the food and beverage industry. The tube-ID port opening is dimensionally identical to the adjacent tubing to comply with ASME-BPE guidelines.

SB79 ball valves are available in sizes 1/2, 3/4, 1, 1 1/2, 2, 2 1/2, 3, 4, and 6 inch

Standard Design

The SB79 Series Hastelloy® ball valve is ASME-BPE compliant. There is a cavity filled TFM1600™ seat option available (SBC79). The valve has a drainable design with tube-ID dimensions. There are weld bosses for easy purge porting on ends and ISO 5211 mounting pad for easy actuation. 

Encapsulated body seals facilitate welding without disassembly. End connections include Tri-Clamp® and extended tube O.D. The standard interior finish is 20Ra or better and the EtO ends are designed for orbital welding. The ball valve includes an exclusive “fine adjust” handle for precise positioning.

OPERATION 

SVF valves provide tight shut-off when used under normal conditions and in accordance with the pressure/temperature chart. If these valves are used in a partially open (throttled) position seat life may be reduced. 

SVF valves have 1⁄4 turn operation closing in a clockwise direction. It is possible to see when the valve is open or closed by the position of the wrench handle. When the wrench is inline with the pipeline, the valve is open.
