The Festo KVZA Butterfly-Valve Configurator lowers overhead by speeding up and simplifying procurement of manual and automated butterfly valves.
This tool provides support throughout the valve procurement process from search to order. All the following are combined into a single tool: configuration, sizing, documentation, request for quotation, ordering, and delivery. In addition to the features listed above, the KVZA tool features a direct link to the Festo Online Shop.
Actuation and automation options are available through the KVZA configurator, including:
- Actuation manual (hand lever) or automated (pneumatic actuator)
- Open/closed or proportional control (positioner)
- Visual indicator, limit switch, or puck sensor
- NAMUR pilot valve
Butterfly valves are available in wafer and lug styles, and DIN and ANSI compatible formats. Nominal diameters range from 1 to 12 inches (DN 25 to DN 300). Shut off materials include ductile cast iron with polyamide (PA) coating, stainless steel with PFA (perfluoroalkoxy alkane) coating, and stainless steel. Sealing element materials include EPDM, NBR, and PTFE with silicone.
Quarter-turn actuators can be either double acting or single acting; low, standard, or high temperature; as well as G or NPT threads for the air connection.
