Overview
ControlAir Type 650 Series, 650-CCZ Positive Bias Air Relay
Features:
- High Flow Capacity: Allows flows up to 50 SCFM.
- Four Bias Ranges: From 0-15 psi to 2-150 psi.
- High Relief Capacity: Large relief valve provides 15 SCFM relief capacity.
- Balanced Supply Valve: Rolling diaphragm design makes unit insensitive to supply pressure variation.
- Accurate Pressure Conversion: High sensitivity achieves accurate conversion of signal to output with no lag.
Options & Features (See Specification Sheet For Full List):
Output Pressure From Input Signal Plus A Preset Bias
The Type 650 positive bias relay is a signal operated regulator that provides an output pressure that is the sum of the input signal pressure plus a preset bias. The unit allows flow capacity ties up to 50 SCFM with minimal pressure drop. An aspirator tube at the output maintains the set pressure under varying flow conditions by causing the main supply valve to open and close proportionally to the flow demand. There is a choice of four adjustment ranges for the positive bias settings. This unit is most often used for conversion of a low flow control signal to the higher flow requirements of an operating system.
