2. General description

Grundfos 24 V zone valves,

UP-ZV, are designed for closed

water heating and cooling

applications. UP-ZV are not

intended for potable water

applications. See section

9. Technical data for additional

specifications.

3. Shipment inspection

On receipt, examine the

components carefully to make

sure no damage has occurred to

the zone valve during shipment.

Take care and ensure that the

zone valve is NOT dropped or

mishandled. Check to see that the

shipment includes:

• one zone valve body

• one zone valve actuator

(motor)

• one installation and operating

instruction manual.

4. Valve body

installation

Caution

If these safety

instructions are not

observed, it may

result in malfunction

or damage to the

equipment.

Note

Notes or instructions

that make the job

easier and ensure

safe operation.

Warning

All work must be

performed by

qualified personnel

trained properly in

the application,

installation and

maintenance of

systems in

accordance with

applicable national,

state and local codes.

Warning

Do not over-tighten

pipe joints.

The PTFE-coating of

pipe joints provides

lubricity, so breakage

can occur if pipe

joints are over-

tightened. Failure to

follow these

instructions could

result in property

damage and/or

personal injury.

• Valves can be installed

vertically or horizontally, but

never upside down. See fig. 1.

Fig. 1 Valve body installation

• The flow direction is indicated

by an arrow on the valve body.

The flow direction is from A to

B and the valve body must be

installed so that the internal

paddle closes against the

direction of flow as indicated in

in fig. 2 and fig. 3.

• Valves can be installed in the

supply or return piping; for

correct installation it is

necessary to respect the flow

direction indicated by the

arrow on the valve body.

• Be sure to have the actuator

removed from the valve body

when soldering.

Warning

Liquid may be under

pressure or

temperature

hazardous. Be sure

the pressure has

been reduced to zero

and the temperature

is at safe levels.

Failure to follow

these instructions

could result in

property damage and/

or personal injury.

7. Valve operation

• The valve is an NC (normally

closed) type of valve, i.e. it is

closed when no power is

applied.

* See fig. 3 for location of Port A

and Port B.

•Automatic operation

When power is applied, the

manual lever will unlock

automatically.

•Manual operation

Slowly move the manual

opening lever to the unlocked

position. See fig. 7.

Fig. 7 Manual opening and

closing of valve

7.1 Switch state

• The end switch contacts are

open when the valve is closed.

• The switch contacts are closed

(call for heat) when the valve is

open (automatically).

• The switch contacts are also

closed when the actuator is

manually opened. This allows

the heating circulation to

function by simply manually

opening the actuator.
