FAIRCHILD - Relays
Designed for applications that require an output pressure that is the sum of a controlled input signal plus or minus a fixed bias, Rotork Fairchild Model 14 Biasing Pneumatic Relay provides versatility in its ability to provide either positive or negative biasing in a single unit.
Features
• The output of the Model 14 relay is the sum of the spring bias, set with the Range Screw, plus a pneumatic input signal. (Po = Ps + K); where Po is output pressure, Ps is signal pressure, and K is the combined spring constant
• Control sensitivity of 1/2" water column allows use in precision applications
• Balanced supply valve minimizes the effects of supply pressure variation
• Aspirator tube design minimizes downstream pressure droop under flow conditions
• Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Mounting bracket available - easy to install in the field
• Certification for use in all Canadian territories and provinces
• Control sensitivity of 1/2" water column allows use in precision applications
• Balanced supply valve minimizes the effects of supply pressure variation
• Aspirator tube design minimizes downstream pressure droop under flow conditions
• Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Mounting bracket available - easy to install in the field
• Certification for use in all Canadian territories and provinces
