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.
● Nominal 135 Ω feedback potentiometer (built-in):
Provides proportional control in combination with a
DDC controller (e.g., Infilex
● Nominal 135 Ω resistance input:
Provides proportional control in combination with a
proportional controlled electric controller (e.g., Neostat
Model TY900_Z, Model TY9800).
● 4-20 mA DC input:
Provides proportional control in combination with a
DDC controller (e.g., Infilex
Model R35/ R36).
● 2-10 V DC input:
Provides proportional control in combination with a
DDC controller (e.g., Infilex
● 0-10 V DC input:
Provides proportional control in combination with a
DDC controller.
„ Features
● Compact and lightweight
● Valve and actuator integrated in a single unit
● Dust- and splash-proof structure (IEC IP54)
Installable in an AHU.
Note: Waterproof connectors are required to ensure IP54.
● A variety of control signals available
● Durable actuator with low power consumption
● 2–10 V DC output with feedback signal
Only for the 4–20 mA DC input type (model VY513_),
the 2–10 V DC input type (model VY514_), and the
0–10 V DC input type (model VY515_)
● Equal percentage flow characteristic
● Valve for water/steam control applicable to high
differential pressure, with large Cv value, wide
rangeability, and low leakage.
