The Georg Fischer Type 175 ball valve is a premium 3-way electrically actuated ball valve with high
stability and excellent flow characteristics. The Georg Fischer Type 175 ball valve offers high chemical
resistance and is especially well suited for aggressive fluids and the heavy-duty requirements of harsh
industrial applications. As a 3-way valve, the Georg Fischer Type 175 ball valve is ideal for applications
requiring diverting and mixing liquids in piping systems for industries such as food and chemical processing.
Designed as a modular unit, the 3-way electrically actuated Georg Fischer Type 175 ball valve combines the
343 series ball valve with the EA21 electric actuator. The EA21 actuator was designed specifically to
complement the modularity and flexibility of the 343 series valve and provide a system approach to piping
system design.
Georg Fischer EA 21 Electric Actuator
The Georg Fischer EA 21 electric actuator is known for its 100 percent duty cycle for continuous operation,
making it the perfect choice for positioning and control. Designed for a long service life of 250,000 cycles,
the Georg Fischer EA 21 / 31 electric actuator comes equipped with integrated emergency manual override and
automatic adjustment of voltage and frequency for on/off or process control applications. The Georg Fischer
EA 21 electric actuator is available with universal automatic voltage adjustment of 100-230 VAC or a 24 AC/DC
power module. Other outstanding features include an IP 67 rated housing manufactured with flame retardant
fiberglass-reinforced polypropylene and all stainless steel screws.
The Georg Fischer EA 21 electric actuator's ISO-Namur connection interface offers greater flexibility in
adding accessories, allowing 10 options available in any combination. These include cycle time adjustment,
current monitoring, cycle time monitoring, cycle counting, fail safe, heating element, and position feedback
for 4 to 20mA input. Users can also quickly obtain status monitoring by installing a display for indication
and configuration directly on the actuator. The Georg Fischer EA 21 electric actuator is CE, CSA, and UL
(pending) certified.
Georg Fischer 343 Series 3-Way Ball Valve
The Georg Fischer 343 series 3-way ball valve is ideal applications requiring diverting and mixing liquids
in piping systems. An L-port version provides independent connection of inlets with outlets, while the T-port
version provides straight through flow, independent connections of inlets with outlets, or interconnections
of all three ports. The Type 343 is available in PVC or CPVC in sizes from ½" – 2" (20mm - 63mm) with EPDM
and FPM seals as well as PTFE ball seats. End connections are solvent cement socket or threaded. A position
indicator on handle and stem allows for easy recognition of function. True union permits radial installation
or removal.
