CT Seris Flex Tube® - Displacer Type Level Controller

DESCRIPTION

The CT (Control, Throttling) Series Flex Tube® has been an industry standard for over five decades in fluid level control. Its simplicity, reliability, ease of maintenance, and rugged construction have made it popular where downtime for repairs could be critical to processes or where minimum maintenance is desirable. (For Flex tube Principle, see page 2. of PDF file)

The general purpose pilot enclosure is suitable for many exposed applications. All exhaust gas is vented inside the enclosure and then to the atmosphere through a screened vent connection.

The pilot cover plate is gasketed and the pressure gauges are of corrosion-resistant materials.

The weather proof pilot enclosure has been developed to provide a weather-tight pilot enclosure to completely protect the control from the elements and even hose cleaning operations. In addition, it allows hazardous exhaust gases to be vented through piping to a safe release area.

An optional Acrylic or Pyrex Sight Glass can be included in Hammer Union models to aid in calibration and operational verification.

ADDITIONAL INFORMATION

Note:


1. Polycarbonate sight glasses are limited to 175°F. For higher temperatures pyrex glasses are available (consult the factory). Pyrex glasses are also recommended for service involving H2S, aromatics such as benzene and toluene, and for service involving undersaturates. Esters, halogenated hydrocarbons, ketone are not compatible. Further chemical resistance information is available from the factory.


2. *Dimensions are worst case and vary slightly from size to size.
Note: Dimensions – Inches to the nearest tenth (millimeters to the nearest whole mm), each independently dimensioned from respective engineering drawings.
