SBC Ball Check Valve

For use in applications with highly corrosive media

Swissfluid fully lined SBC Ball Check Valves are primarily used in applications with highly corrosive media, and are suitable for horizontal and vertical piping systems. Due to the solid PTFE ball residing in a high-volume chamber, pressure losses are minimal. The flexible sealing lips at the ball seat area enable positive shut-off with very low pressure differentials. Conversely, the ball allows media to flow freely during the entire opening operation.

This flanged valve is easily and securely installed in DIN as well as ANSI piping systems, and the body is clearly marked with a directional arrow. The robust and maintenance-free design utilizes ASTM A-216 WCB (1.0619) as standard body material. Bodies can also be furnished in AISI A316 stainless steel (CF-8M / 1.4408) and AISI A316L (CF-3M / 1.4404) for service in corrosive atmospheres. Face-to-face dimensions are in accordance with EN 558-1 row 20 and ASME B16.10.

PFA and PFA-AS (anti-static) linings are mechanically locked in place. The standard material for the solid ball is virgin PTFE, but balls made from polypropylene, hollow PTFE balls, and encapsulated metal balls are also available.
The standard borosilicate glass plates (which meet DIN 7080 specifications) allow safe visual control of liquid or gaseous process media at all times. SBC Ball Check Valves are suitable for vacuum applications and can safely operate at temperatures of -40°C (-40°F) to 200°C (392°F), and maximum differential pressure of 10 bar (145psi).
