Azbil ACTIVAL VY51 J Series Specifications & Instructions

Motorized Two-Way Valve with Flanged-End Connection
for High Differential Pressure Application
General
ACTIVAL Model VY51XXJ for high differential pressure
application is a series of motorized two-way valves with
flanged-end connection.
integrated in a single unit.
The valve size ranges from DN15 to DN150. The actuator
has a reversible synchronous motor, which operates at a low
voltage of 24 V AC.
4 kinds of control signals are available to operate ACTIVAL.
1. Built-in 135 Ω feedback potentiometer:
Provides proportional control in combination with a DDC
controller, including Infilex
2. Nominal 135 Ω resistance input:
Provides proportional control in combination with a
proportionally controlled electric controller, including
™
Neostat (Model TY900XZ/TY9800).
3. 4-20 mA DC input:
Provides proportional control in combination with a direct
digital controller (DDC), including Infilex
WY5111) and Model R35/R36.
4. 2-10 V DC input:
Provides proportional control in combination with a DDC
controller, including Infilex

Features
•
Applicable to high differential pressure applications:
Water flow is controlled inside the valve to prevent over
pressure drop, leading to cavitation erosion resistance.
(See Fig. 1.)
•
Compact and lightweight:
Rotary motor actualizes small body and light weight.
•
Valve and actuator integrated in a single unit:
Pre-assembled body requires no adjustment.
