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)
