Series 520-SN (3-Way – Optional 4/5 Way Sanitary Valve)
Unlike two-seated diverter valves and other multi-port valves on the market, the 520-SN series has four seats (five seats in bottom entry valves) for positive shut-off in the closed position. High-Cycle, Live-Loaded Stem Packing Dynamic loading on stem packing ensures a tight seal through varying pressure and temperature conditions, extending service life and reducing maintenance costs.
SANITARY 3-WAY BALL VALVE SERIES; STAINLESS STEEL
The 520-SN is a true multi-way sanitary style ball valve with balanced seat construction. Porting and shut-off capabilities can reduce the number of process valves required in a piping system. This full port valve is available in a number of flow configurations with both clamp and tube butt weld end connections. Lateral forces in a 3-way valve can cause unwanted seat distortion. tem/ball isolation prevents side loading and wear of downstream seats improving performance and service life. The series 520-SN valve offers the following add-on options: 4 or 5 way construction withmultiple flow patterns, clamp, tube butt weld, extended tube butt weld or compression end connections and finer internal surfaces are available upon request.
PHARMACEUTICAL, FOOD & BEVERAGE AND MEDICAL VALVE APPLICATIONS
The series 520-SN is an ideal choice valve for the pharam, food/drinking water/beverage and medical industries. With optional cavity filler, the 520-SN would be perfect for handling food, drinking water and medical chemicals/waste. The cavity filler will enable and ensure the reduction of contamination and particles embedding in areas of the valve and ball.
