Series 5500 Float Operated Level Controls with cast iron external chamber.

The 5500 series is designed for external mounting on tanks, surge tanks or boilers up to 16 bar and 205°C.
On the standard model the float chamber is in cast iron G25 with screwed process connections as indicated in the table below, while the internal elements are in AISI 316, the float is in AISI 316 L, and the attraction sleeve is in AISI 446.

The opening flanged type case enables the internal organs to be checked and maintenance to be carried out.

There are two basic models: the first, with very small dimensions, can be fitted with a single type 1, 2 or 3 switch mechanism: it comes with a differential of about 20 mm as standard, which can be extended in range up to 40 mm.

The second device has a longer chamber which allows differentials of up to 75 mm in single-stage applications, or allows the use of several switch mechanisms in sequence: up to 3 SPDT or 2 DPDT for type 1, 2, and 3 mechanisms or a single type 4 and 5 mechanism.

Some of the models come with a brass anti-scaling element inside the body that reduces the formation of lime scale deposits, and a manual switch rearming device (only with switch housing type 1 protection IP 40). Manual rearming can also be provided on request for increasing (high level) switching on models 5511 ÷ 5552.
