APPLICATION
The MCV2500 series hydronic valves are designed for
residential heating and cooling applications.
The MCV2500 series 2-position hydronic valves are
used in residential and small commercial applications
to control the flow of hot and/or cold water. They
consist of actuator and valve.
2-way valves are designed for ON-OFF "zone" control
of domestic systems.
3-way valves can be piped for mixing valve
applications to control individual fan coil, baseboard
radiator in domestic central heating and/or cooling
systems.
2-way valves are suitable from A to B, and 3-way
valves are for mixing water from A or B to AB.
Depending on the model selected they can be
controlled by a low or line voltage SPST or SPDT
controller, such as a room thermostat, aquastat or flow
switch.

WARNING
CAUTION
Take care that installer is a trained experienced service
person.
Disconnect Power Supply before making electrical
connections to prevent electrical shock and
equipment damage.
When installing this product:
Read these instructions carefully.
Failure to follow them could damage the product or
cause a hazardous condition.
Check the ratings given in the instructions and on the
product to make sure it is suitable for your application.
Always conduct a through checkout after installation.
INSTALLATION
WIRING DIAGRAM
1. The valve may be plumbed in any angle but
preferably not with the actuator head below the
horizontal level of the valve body. Make sure there is
enough room around the actuator head for servicing
or replacement.
2. The valve body can be mounted directly onto the inlet
pipe. Mount the metal flange inserted in socket to
outlet pipe. And then tighten the socket enough to
make a seal. See Figure 1~2 for the detail dimension.
3. Mount the valve directly in the tube or pipe. Do not
grip actuator head while making and tightening
plumbing connections. Either hold valve body in your
hand or attach adjustable spanner across the
hexagonal or flat faces on the valve body.
