The filling valve is used for filling closed heating systems and regulating their pressure. The control wheel allows you to set the desired output pressure. The integrated pressure reducing valve compensates for fluctuations in the input pressure, ensuring that the output pressure remains unaffected. A non-return valve is also included to protect the drinking water supply from backflow from the heating system.

The valve can be retrofitted with a pressure gauge for precise monitoring of the pipe pressure. The pressure gauge must be purchased separately. The desired pressure is set on the control wheel scale.

The valve consists of the valve body, spring cover with control wheel and scale, spring, valve insert, built-in non-return valve, shut-off valve insert with a knurled control wheel. The valve features both external and internal threaded connections at both ends for greater flexibility.
