Lug butterfly valve Type 146 PVC-C electric 100-230V

  Datasheet (PDF)

The Georg Fischer Type 146 lug-style butterfly valve in PVC-C is an electrically actuated industrial valve engineered for precise modulating control and secure terminal line isolation in demanding process environments. Actuated by a reliable 100-230V, 50-60Hz electric actuator unit, the assembly operates with a factory-set 90 degrees travel angle to achieve dependable throttling and bubble-tight shut-off without manual override. The lug-style body is designed with integrated threaded inserts, enabling straightforward mechanical connection between pipeline flanges as well as safe end-of-line servicing where downstream equipment requires maintenance under operating system pressure.

Constructed from high-performance chlorinated polyvinyl chloride (PVC-C) in Agate Grey RAL 7038, this motorized valve exhibits superior mechanical rigidity and resistance against harsh chemical media, including mineral acids, alkalis, and salts at elevated process temperatures. The actuator housing, molded from glass-fiber reinforced polypropylene (PP-GF), ensures high impact resistance and IP-rated ingress protection. An integrated internal heating element continuously prevents moisture condensation within the electrical compartment, while integrated limit switches provide exact position feedback across Open, Close, and Middle states for automated supervisory control systems.

Designed for seamless compatibility across metric industrial piping layouts from outer diameter d63 mm up to d315 mm, the Type 146 valve supports nominal pressure classifications of PN10, PN6, and PN4 depending on the nominal diameter. Media containment is maintained by precision sealing variants in EPDM or PTFE compounds. The lug mounting hole pattern conforms to EN 1092 PN10, ISO 7005 PN10, DIN 2501 PN10, and ASME B16.5 Class 150 bolt circles, with actuator mounting governed by ISO 5211 mechanical standards. These characteristics deliver dependable service life across chemical manufacturing, surface treatment, semiconductor fabrication, and industrial wastewater treatment plants.
