Motorized Two-Way Valve with Flanged-End Connection
Overview
TM
ACTIVAL
Model VY51_ _J is a series of motorized two-
way valves with flanged-end connection. Rotary valve and
actuator are integrated in a single unit.
Valve size ranges from DN15 (1/2") to DN80 (3"), and valve
body rating corresponds to ISO PN16.
Actuator has a reversible synchronous motor, which operates
at a low voltage of 24 V AC.
5 kinds of control signals are available to operate ACTIVAL.
1. Nominal 135 Ω feedback potentiometer (built-in):
Provides proportional control in combination with a DDC
controller (e.g., Infilex
TM
2. Nominal 135 Ω resistance input:
Provides proportional control in combination with a
proportional controlled electric controller (e.g, Neostat
Model TY900_Z, Model TY9800).
3. 4-20 mA DC input:
Provides proportional control in combination with a DDC
TM
controller (e.g., Infilex
R36).
4. 2-10 V DC input:
Provides proportional control in combination with a DDC
TM
controller (e.g., Infilex
5. 0-10 V DC input:
Provides proportional control in combination with a DDC
controller.
