Two-way Ball Valve with Threaded-end Connection
General
ACTIVAL™ Model VY5302A is a two-way ball valve with
threaded-end connection (ISO 7-1: 1994). It proportionally
controls chilled/hot water for HVAC applications.
Model VY5302A has bronze valve body, stainless-steel ball
and stem, and the components exposed to process fluid are
made of other corrosion resistant materials.
Cv value and size variation of Model VY5302A are best
suited to HVAC control.
Model VY5302A is used in combination with the actuator
Model MY53X0A. Regarding the detailed information on the
actuator, refer to:
Specifications/Instructions of ACTIVAL Model MY53X0A
HVAC: Heating, ventilation, and air conditioning
ISO: International Organization for Standardization

Specifications/Instructions
Features
● Compact and lightweight:
Valve can be installed in a restricted space such as
inside of a compact AHU.
● Bronze valve body applicable to PN16.
● Easy assembly with Model MY53X0A actuator using no
tool, and no adjustment required.
● Equal percentage flow characteristic.
AHU: Air handling unit
IMPORTANT:
To control ACTIVAL with a third-party controller,
please consult with our sales person.

Warnings and Cautions
WARNING
CAUTION
Signs
Alerts users possible hazardous conditions caused by erroneous operation or erroneous use. The symbol inside I
indicates the specific type of danger.
(For example, the sign on the left warns of the risk of electric shock.)
Notifies users that specific actions are prohibited to prevent possible danger. The symbol inside Q graphically
indicates the prohibited action.
(For example, the sign on the left notifies that disassembly is prohibited.)
Instructs users to carry out a specific obligatory action to prevent possible danger. The symbol inside d graphically
indicates the actual action to be carried out.
(For example, the sign on the left indicates general instructions.)
Install and use the product under the operating conditions requirement (temperature, humidity, power, vibration,
shock, mounting direction, atmospheric condition, etc.) as listed in the specifications.
Failure to do so might cause fire or device failure.
Use the product within its lifespan and avoid instrumentations that keep the product to operate excessively.
Continued use beyond the lifespan might cause fire or device failure.
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
Install the product in the proper position as specified in this manual.
Excessively tight connection to a pipe or improper installation position might damage the product.
After installation, make sure no fluid leaks from the valve-pipe connections.
Incorrect installation might cause fluid leakage.
Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer (suitable for the
process fluid) on the inflow side of the piping. Flush the piping to remove the foreign objects after installation.
Foreign objects inside the piping might damage the product.
Do not excessively screw the valve into a pipe.
Doing so might damage or deform the inside of the valve causing leakage and malfunction.
Do not allow process fluid to freeze.
Doing so might damage the valve body causing leakage.
Do not install the product nearby a steam coil or a hot-water coil.
High temperature radiation might cause malfunction of the actuator assembled with the valve.
Do not use the product in an atmosphere corrosive to the product, its actuator, and their components.
Doing so might damage the product.
Do not disassemble the product.
Doing so might cause device failure.
Do not carelessly touch the product when being used to control hot water.
The product temperature goes high, and you might get burned.
Dispose of the product as industrial waste in accordance with your local regulations.
Do not reuse all or part of this product.
Alerts users that improper handling may cause death or serious injury.
Alerts users that improper handling may cause minor injury or material loss.
