Azbil ACTIVAL VY519 J Series Specifications & Instructions

Motorized Two-Way Valve with Flanged-End Connection
<4-20 mA DC Input with 4-20 mA DC Feedback Output>

Overview
ACTIVAL Model VY519_J is a series of motorized two-way
valves with flanged-end connection. The 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.
The actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC.
4-20 mA DC input control signal provides proportional control
in combination with a PLC (e.g., Model R35/R36).
 Notes
JIS: Japanese Industrial Standards
PLC: Programmable Logic Controller

Features

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.

Valve for water/steam control applicable to high
differential pressure, large Cv value, high rangeability,
and low leakage.

Durable actuator with low power consumption.

Equal percentage flow characteristics.

4-20 mA DC output available for position feedback.

Open/close changeover for input signal failure:
Actuator fully opens/closes valve in case that the control
signal is not input to the actuator. (Default: Fully open)

Direction changeover of control action:
Open/close action by 4-20 mA DC input signal is
reversely controllable.
Normal action 4 mA: 0 % to 20 mA: 100 %
Reverse action 20 mA: 0 % to 4 mA: 100 %.
(Default: Normal action)


Adjustable dead band*:
Dead band width can be narrowed to more precisely
operate valve actuator.
 Actuator is not operated by input signal changed less than a
certain amount. This amount of change is called dead band.
IMPORTANT:
 The service life of ACTIVAL operated with small
dead band can be shortened since the ACTIVAL
operates more frequently with small dead band
than with normal dead band.
 Use shielded cable for the ACTIVAL with small
dead band. Noise may affect the signal
transmission causing operation error, otherwise.
 To control ACTIVAL with a third-party controller,
please consult with Azbil Corporation's sales
personnel.
