GEA Hygienic Butterfly Valves are characterized by their hygienic design without dome and sump. The product flow meets little resistance, product areas drain automatically and cleaning proceeds efficiently. GEA Hygienic Butterfly Valves offers the benefits of good hygienic design, higher ease of assembly, shorter assembly and maintenance times and thus higher production uptimes.
Function
Robust valve disk
Low switching torque
One-piece flange design
Selection of 2 metallic product wetted materials
Product wetted parts in AISI 304 (1.4301) or AISI 316L (1.4404)
Pneumatic actuators Pneumatic actuators For narrow mounting situations and low air consumption the pneumatic actuators have been made even more compact. The gap-free design ensures optimum cleanability and fulfils highest demands to hygiene. Torque maxima towards both end positions enable application on both normally closed and normally open valves. Metallic stops ensure exact disk positioning. There are air-to-spring and air-to-air variants. All actuators are by default applicable for Ex zones. Compliance of any electric accessories with Ex regulations must be ensured.
The integrated T.VIS® interface also safely accommodates optional accessories – booster cylinder, two-position stop and limit stop. The internal pneumatic system reduces the risk of failures, being without external tubing.
