ACTIVAL™
Motorized Two-Way Valve with Flanged-End Connection (Spring Return Type Actuator)

A series of motorized two-way valves, DN15 (1/2”) to DN80 (3”) , with flanged-end connection.

ACTIVAL™ Models VY51_ _K and VY51_ _H are series of motorized two-way valves, DN15 (1/2”) to DN80 (3”) , with flanged-end connection. 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.
The actuator fully closes the valve in case of power failure, so it is suitable for failsafe applications.
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 R35/R36)
  • 2-10 V DC input
    Provides proportional control in combination with a DDC controller. (e.g., Infi lex AC Model WY5117)
