Butterfly valve 146 PP-H 230V

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 146 lug-style butterfly valve provides dependable, electrically automated flow isolation and throttling control across industrial piping networks. Fabricated from polypropylene homopolymer (PP-H), this industrial valve is specifically engineered to handle aggressive chemicals, acids, bases, and process fluids where metallic valves suffer from severe corrosion. The integrated electric actuator operates across an input voltage of 100 to 230 V at 50/60 Hz, ensuring complete electrical compatibility throughout European industrial installations. Featuring a factory-preset 90 degrees actuating angle, the actuator delivers precise quarter-turn operation to safeguard critical fluid handling processes.

At the mechanical core of the Type 146 valve is an advanced double eccentric disc geometry. This off-centre disc configuration detaches the sealing surface immediately upon opening, substantially reducing operating torque and eliminating mechanical wear across the seal interface during frequent cycling. Depending on media requirements, the valve is equipped with resilient EPDM or chemically resistant PTFE gaskets, maintaining bubble-tight shut-off across nominal pressure ratings of 10 Bar, 6 Bar, or 4 Bar. The lug-style body includes threaded inserts that facilitate end-of-line installation and downstream pipeline servicing without draining the entire system. Available in metric dimensions from outer diameter 63 mm up to 315 mm, it connects directly into thermoplastic piping layouts.

The integrated 230V electric actuator incorporates an internal heating element to prevent condensation build-up inside the housing under varying ambient temperatures. Multi-point position feedback provides continuous process monitoring, transmitting clear signals for Open, Close, and Middle positions to central PLC and SCADA industrial automation systems. As an authorised Georg Fischer distributor, BigWeld supplies authentic Type 146 electrically actuated butterfly valves tailored for chemical distribution networks, electroplating processes, and industrial water treatment installations across Europe.
