ACTIVAL™ Model VY51_ _J is a series of motorized twoway rotary valves, DN15 to DN150, 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
  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 R35/R36)
• 2-10 V DC input
  Provides proportional control in combination with a DDC controller. (e.g., Infi lex AC Model WY5117)
