Model FVY51_FJ is a series of motorized two-
way valves with flanged-end connection. Rotary valve and
actuator are integrated in a single unit.
In combination with the functions of a control valve, Model
FVY51_FJ measures and controls flow. Model FVY51_FJ
thus enables to control temperature for air conditioning by
controlling chilled/hot water volume and to measure chilled/
hot water flow.
For such a high functionality, compact size and simple
installation of Model FVY51_FJ are incomparable.
Model FVY51_FJ is operated by the following control signal.
1. 4–20 mA DC input
2. 2 to 10 V input
Both provide proportional control in combination with a
single loop controller (e.g., Model SDC35/SDC36)
Flow data stored in Model FVY51_FJ is retrieved via RS-485
communication (Modbus protocol). The retrieved flow data is
effective for energy-saving facility operation.
Features
•
Compact and lightweight:
Rotary valve actualizes small body and light weight.
•
Valve and actuator integrated in a single unit.
•
NEMA 4X and IP54 enclosure rating
(Waterproof connectors are required to assure NEMA 4X
and IP54)
•
Valve for chilled/hot water control applicable to large Cv
value, high rangeability, and low leakage.
•
Durable actuator with low power consumption.
•
Flow control/position control operation selectable:
For flow control, flow characteristic is selectable
(equal percentage or linear). For position control, flow
characteristic is equal percentage.
•
Model FVY51_FJ holds flow data effective for
maintenance and energy-saving facility operation. The
data is retrieved via RS-485 communication (Modbus
protocol).
•
In combination with the optional Display Panel (Model
QY5010S2000) and the insertion-type temperature
sensor (Model TY7830) or the temperature sensor for
pipe surface (Model TY7820), pressure, temperature,
and flow can be displayed on the Display Panel.
Note: The display panel, the insertion-type pipe temperature
sensor, and the temperature sensor for pipe surface should be
ordered separately.
IMPORTANT:
Do not use the data measured by this product for charging or dealing purposes.
