FRICO VR25 Valve Kit
For regulating the waterflow in water-heated units. The VR20/25 contains the following parts:
- AV20/25, off regulator valve
- JVF20/25, balancing valve
- TRV20/25, 3-way valve
- SD20, actuator on/off 230 V~ (“soft closing”)
- BPV10, bypass valve
The off regulator (AV20/25) is either set to be closed or open and it’s therefore used when no waterflow is wanted, for example during maintenance. With the balancing valve the waterflow can be manually adjusted or be closed completely. NB! Completely closed balancing valve is not 100 % secure of water leakage. The adjusted waterflow can be read directly on the valve without any other instruments. If the 3-way valve is closed, the waterflow will pass by through the bypass valve (BPV10). The bypass valve is used for a certain frost protection or when hot water should always exist in the waterbattery at all times, for example in case of a door opens and a quick heat supply is needed. The actuator (SD20) regulates the water supply on/off and it’s “soft closing” just to avoid noise and pressure blow in the pipe system. The set of valves has two different dimensions. The VR20 has DN20 (3/4″) which has the total Cv- value of 3,01 and the VR25 has DN25 (1″) has the total Cv-value of 4,70. The bypass valve has a DN10 (3/8″). For regulating the VR20/25 complement with an appropriate thermostat.

Off regulator valve (AV20/25)
(104507107 / 104510107)
Application
The off regulator valve is used to turn off the water supply to the unit. It’s
either open or closed and has no balancing functions. It’s therefore usually
used for maintenance and service purposes.

Balancing valve (JVF20/25)
(D3498295 / D3498355)
Application
The balancing valve is intend for balancing heat or cooling systems. It’s used
to adjust a certain waterflow/pressure over the pipe system and can also be
used as an off regulator. NB! Completely closed balancing valve is not 100 %
secure from water leakages. JVF balancing valve is provided with an integrated
waterflow instrument, that continuously measures the actual waterflow. By
using the adjustment screw, the waterflow can easily be adjusted and measured
without any other measure instruments. It’s possible to read the actual
waterflow even when the valve is isolated. The actual waterflow can easily be
readed from any angle though the measuringscale can be rotated. The fluid
doesn’t pass by the integrated measure instrument which eliminates the risk
for any contamination; continuously reading can therefore take place long time
after the installation. There is also a socket for measuring pressure with an
external instrument. JVF balancing valve has an unchanged waterflow profile
inside. It’s therefore sufficient with a straight piece of tube before the
inlet that has the same diameter and length as the valve itself.

3-way valve (TRV20/25)
(VG5800KC / VG5800MC)
Application
TRV20/25 (3-way valves) are primarily designed to regulate the flow of water
in responce to demand of a controller. These valves are made in forged brass
and stainless steel stem which ensures a long life. The valves should be used
in combination with an electric on/off actuator. The actuator can be mounted
after piping, this simplifies installation in confined locations. The valves
have even a built in return spring which allows the valves to return to normal
position when the actuator is de-energized.
Choice of valve
The right dimension of the valve can be decided from the diagram below. Keep
in mind that the pressure drop and the flow of water must be kept within the
white indicated field.
Pressure drop p, [kPa] (1 kPa = 10 mBar = 100 mmWK)
Operating
When power is applied the actuator pushes the valve stem down against the
return spring which allows the waterflow to pass by. When de-energized the
return spring will return the valve to it’s normal position, a closed valve.
Mounting
The valve must be mounted in the direction of the arrow according to the
direction of the flow of water that pass by the valve. Valve with an actuator
must be mounted within 90 degrees of the upright position, free from dripping
water and easy accessible for the electrical wiring.

Material
Application
The electrical actuator in combination with the 3-way valve (TRV20/25) is used
for regulating the heat supply to the unit. It’s function is to open or close
the valve (on/off). The actuator will open the valve when power is applied.
The actuator is “soft closing” just to avoid noise and pressure blow in the
pipe system. The electrical actuator can be mounted and rotated after that the
valve has been installed. For regulating the actuator in combination with
valve complement with appropiate thermostat.
Mounting
Never use the actuator as a mounting lever. Make sure the actuator is free of
thermal insulation connections and leave at least 20 mm clearance above the
actuator for mounting purposes according to the figure below.
Technical specifications
Application
The bypass valve is used when a small amount flow of water should pass by the
unit at all times. The purpose of this is that the water should always stay
hot in the watercoil, in cases when a door opens and a quick heat supply is
needed. This kind of valve has the dimension DN10 (3/8″). When mounting the
plug inside the valve must be screwed entirely at first and then screwed back
a whole lap. In cases where the distance between inlet and the unit is far
away, open the plug even more by screwing the plug backwards.
