Series 8800

Series 8800 Displacer Operated Level Controls with External Chamber for high-pressure systems.

The 8800 series models feature a displacer chamber that can be opened, enabling the internal elements to be checked and maintenance carried out. They are designed for external application to very high pressure systems, such as hydraulic accumulators and natural gas compressors, for control of very low-density liquids (down to 0.4 kg/dm³). In the standard model the chamber is in carbon steel, fitted with sealing flanges of dimensions conforming with AMSE CODE, Section VIII, Div. 1, App. 2.

The standard model comes with 1" NPT process connections; 1" SW connections are also available, to which 1", 1½" and 2" flanges can be applied in the configurations and face-to-face dimensions shown below.

The internal elements are in AISI 316 stainless steel, the displacer is in AISI 316 L for model 8801, in Karbate for models 8802-3-4, the contrast spring is in "INCONEL" and the attraction

sleeve is in AISI 446. All the models in this series can be fitted with a single switch mechanism; the factory settings allow them to work with all liquid density values, with the minimum limit shown in the table below.
