Azbil Intelligent Component Series Specifications & Instructions

with Flanged-End Connection (JIS 10K / FC200, SCS13A)
General
™
ACTIVAL Models VY516XK and VY616XH are 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 JIS 10K.
Actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC. Since the actuator fully
closes the valve in case of power failure, it is suitable for
failsafe application.
Model VY516XK/VY516XH communicates with a controller
via SAnet (Azbil Corporation's communication protocol).

Features
•
Compact and lightweight:
Rotary valve actualizes small body and light weight.
•
Valve and actuator integrated in a single unit:
•
SAnet communication:
Intelligent Component Series ACTIVAL communicates
with a controller via SAnet, and thus position control
signal/position feedback signal is input/output from/to the
controller.
•
Valves for chilled/hot water control and for steam control
applicable to large Cv value, high rangeability, and low
leakage.
•
Durable actuator with low power consumption.
•
Equal percentage flow characteristic.

ACTIVAL
Motorized Two-Way Valve
(Spring Return Type Actuator)
™
•
Spring return actuator:
Actuator automatically closes the valve in 0 % position in
case that the power is down.
•
Interlock signal input to fully close the valve:
Interlock input signal to forcibly close the valve in 0 %
position is provided.
•
Sub-DO for wire saving:
Sub-DO (digital output) provided takes a signal,
including a humidifying output of a neighboring device,
leading to wire saving.
•
CE Marking certified product:
Models VY516XK and VY516XH conform to all the
applicable standards of CE Marking.
