Float valve, DN 17, with vertical guide float

This servo-controlled valve has an orifice size of 17 mm and is operated by means of a float to control the level in a tank.

If liquid is drained from the tank, the float valve opens automatically and then closes when the maximum level has been reached.

Whilst the water level and float rise, the flow into the tank is reduced proportionally to the float arm's position. This helps prevent overflow during the initial filling of small tanks when there is a grater level of liquid turbulence.
Whilst reaching the maximum level in the tank, the float lever will be lifted faster ensuring a full flow for longer. It then has a shorter closing time, which in turn significantly reduces dripping of the valve during this operation.

Valves of this design are single chamber valves with the inlet and outlet in line.
The valve has a glass fibre reinforced polyamid body and can be manufactured with various connection ports. It is suitable for use with medium temperatures of up to 60 °C when specified with a PE-float.
