Secondary Packed Bellows-Sealed Valves, SU Series

Ideal for high purity and ultra high purity applications

SU Series Secondary Packed Bellows-Sealed Valves are constructed from 316/304 stainless steel or brass valve bodies. These valves feature a working pressure of up to 2500 psig (172 bar) and a temperature range from -20°F to 842°F (-28°C to 450°C). The hydraulic-formed multilayer bellows, combined with upper packing above the bellows, provide a secondary containment system that ensures excellent sealing and longer cycle life. The externally pressurized bellows design increases pressure containment capacity, while the non-rotating stem tip reduces galling. Bellows and stem tip assemblies are replaceable, with regulating, conical, and spherical tip options. Manual and pneumatic actuation are available.
