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.

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.
