CT Flex Tube Level Control
General Purpose Enclosure
The CT 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.
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 made of corrosion-resistant materials.
Weatherproof Enclosure
The weatherproof 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 operation verification.
Model CMAS-203 Level Control
The Model CMAS-203 utilizes a stainless steel ball-type float and a three-way snap-action MICRO VALVE to provide a positive pneumatic output for control of liquid level.
- Override feature permits adjustment of set points without disturbing process level.
- Adjustable Span allows for pump up and pump down control. Easy-to-set desired level detection point.
- Proven MICRO VALVE unit provides long life and ease of maintenance.
- Electronic version available: Model CMEASX-203
Model CMAQ/CMAF Level Controls
The Models CMAQ and CMAF are snap-action, float operated level controls, equipped with the popular three-way MICRO VALVE unit, actuated by two adjustable yoke-type pusher arms. Adjustable pusher arms permit the control range to be adjusted easily and accurately to the range desired. With the liquid level below the float, the three-way MICRO VALVE will be in the low level position and will remain there until the float rises to the preset high level. The MICRO VALVE will reverse positions until the float drops to the preset low level position.
Adjustable span allows for pump up and pump down control. Easy-to-set desired level detection point.
Proven MICRO VALVE unit provides long life and ease of maintenance.
Over 35 years of proven field service demonstrates product reliability.
Steel or ductile iron models are Nace adaptable for use in harsh, corrosive service.
Standard gear stem assembly is 303 Stainless Steel; 316 Stainless Steel is optional (consult factory).
