Motorized Two-way Valve with
„ Overview
ACTIVAL Model VY51_ _ is a series of motorized two-
way rotary valves, DN15 (1/2") to DN80 (3") , with
flanged-end connection. The 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.
There are following four control signals available.
• Nominal 135 Ω feedback potentiometer
Provides proportional control in combination with a
DDC controller. (e.g., Infilex 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., Infilex GC Model WY5111,
Model R35/R36)
• 2–10 V DC input
Provides proportional control in combination with a
DDC controller. (e.g., Infilex AC Model WY5117)
