Motorized Two-Way Valve with Flanged-End Connection
<4-20 mA DC Input with 4-20 mA DC Feedback Output>
General
TM
ACTIVAL
Model VY519XJ is a 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 ISO PN16.
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).
* 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 chilled/hot water control and for 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)
* Although our company name changed from Yamatake Corporation to Azbil Corporation on April 1, 2012, our former logo remains on this product.

•
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.
•
CE Marking certified:
ACTIVAL Model VY51 conforms to all the applicable
standards of CE Marking.
