ACTIVAL™ Model VY54_0F is a series of motorized three-way rotary valves, DN50 (2") to DN80 (3") , with flanged-end connection. The valve and actuator are integrated in a single unit.
The valve body rating corresponds to JIS 10K.
The actuator has a reversible synchronous motor, which operates at a low voltage of 24 V AC.
There are following four control signals available.

• Nominal 135 Ω feedback potentiometer (built-in)
  Provides proportional control in combination with a DDC controller. (e.g., Infi lex GC Model WY5111)
• Nominal resistance 135 Ω input
  Provides proportional control in combination with a proportionally controlled electric controller. (e.g., Neostat Model TY900_Z) , insertion type Thermostat Model TY9800)
• 4-20 mA DC input
  Provides proportional control in combination with a DDC controller. (e.g., Infi lex GC Model WY5111, Model R15)
• 2-10 V DC input
  Provides proportional control in combination with a DDC controller. (e.g., Infi lex AC Model WY5117)
