Specifications/Instructions
Standalone Model
(JIS 20K / SCPH2)
General
A
Model FVY513EJ/FVY514EJ 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 JIS 20K.
In combination with the functions of a control valve, Model
FVY513EJ/FVY514EJ measures and controls flow. Model
FVY513EJ/FVY514EJ 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 FVY513EJ/FVY514EJ are incomparable.
2 kinds of control signals are available to operate the Model
FVY513EJ/FVY514EJ.
- 4-20 mA DC input:
Provides proportional control in combination with a DDC
controller. (e.g., Infilex
GC Model WY5111, Model
R35/R36)
- 2-10 V DC input:
Provides proportional control in combination with a DDC controller. (e.g., Infilex
AC Model WY5117)
Flow data stored in Model FVY513EJ/FVY514EJ is retrieved via RS-485 communication (Modbus protocol). The retrieved flow
data is effective for energy-saving facility operation.
* JIS: Japanese Industrial Standards
* DDC: Direct Digital Control
Features
Compact and lightweight:
Rotary valve actualizes small body and light weight.
Valve and actuator integrated in a single unit.
Model FVY513EJ/FVY514EJ holds flow data effective
for maintenance and energy-saving facility operation.
The data is retrieved via RS-485 communication
(Modbus protocol).
Valve for chilled/hot water control applicable to large Cv
value, high rangeability, and low leakage.
Durable actuator with low power consumption.
Flow rate control/position control operation selectable:
For flow rate control, flow characteristic is selectable
(equal percentage or linear). For position control, flow
characteristic is equal percentage.
In combination with the optional Display Panel (Model
QY5010S1000) and the insertion-type pipe temperature
sensor (Model TY7830) or the temperature sensor for
pipe surface (Model TY7820), pressure, temperature,
and flow can be displayed on the Display Panel.
IMPORTANT:
Do not use the data measured by this product for charging or dealing purposes.
