Motorized Two-Way Valve with Flanged-End Connection
(Spring Return Type Actuator)
„ Overview
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)
„ Features
• Compact and lightweight
• Valve and actuator integrated in a single unit
• Conforms to IP54 (dust-proof, splash-proof)
Can be installed in AHU.
Note: Waterproof connectors are required to assure IP54.
• A variety of control input 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_)
and the 2–10 V DC input type (Model VY514_) .
