ACTIVAL™ Model VY51_ _ is a series of motorized twoway rotary valves, DN15 (1/2”) 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
Provides proportional control in combination with a DDC controller. (e.g., Infilex 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., Infilex GC Model WY5111, Model R35/R36) - 2–10 V DC input
Provides proportional control in combination with a DDC controller. (e.g., Infilex AC Model WY5117)
-DDC: Direct Digital Control
-JIS: Japanese Industrial Standards
