VF 06
Filling valve
for closed heating systems
Product specification sheet
Application
The VF 06 filling valve permit simple and safe filling or refilling of
a closed heating system.
A pressure reducing valve, a check valve and a shutoff facility
are combined in one unit. The pressure gauge connection
enables fitting of a pressure gauge (available as an accessory)
to provide accurate checking of the pressure of a system after
filling.
Special Features
● Housing with internal and external threads
● One turn of the adjuster knob and the valve is set
● Setting directly readable on the adjuster knob
● Complett replaceable high grade synthetic material insert
● DIN/DVGW approved check valve
● Balanced-seat pressure reducing valve - inlet pressure
fluctuations do not influence outlet pressure
● Integral shutoff facility
● Alternative connections
Construction
The filling valve comprises:
● Housing
● Spring bonnet with setting scale

Method of Operation
The integral pressure reducing valve operates by means of a
force equalising system. The force of a diaphragm operates
against the force of an adjustment spring. The inlet pressure
does not influence either opening or closing of the valve. Inlet
pressure fluctuations do not therefore influence the outlet
pressure, thus providing inlet pressure compensation. An
integral check valve protects the drinking water supply by
allowing water to pass through in only one direction. In the flow
direction, a seal disc is pushed open against the force of a
spring by differential pressure.

Installation Guidelines
● Set adjuster scale to system filling pressure required
● Disconnect hose connection from filling valve after filling
● Check system pressure after every filling or refilling
● Ensure good accessibility
❍ Simplifies maintenance and inspection
Typical Applications
The VF 06 filling valve permit simple and safe filling or refilling of
a closed heating system.
Filling valves can be installed:
● Onto a heating circuit distributor manifold
● In combination with a water supply distributor manifold
● On a heating boiler via a fill hose
● In the supply to a heating boiler
● Directly onto a heating boiler
● As a filling set for trouble-free and safe initial filling of
a system
