Design Features
  • Self-contained actuator
  • No external power or remote signal
  • In line serviceability
  • Insensitive to line pressure
  • Valve opens/closes gradually,preventing system shock
  • High repeatability: No set point drift
  • Set points from 35 to 255°F
  • Max working pressure 200 psig
  • 100% factory tested
Benefits
  • Easy installation
  • Reliable, unattended operation
  • Minimal maintenance requirements
Note: Specify temperature between 35° and 255°F in 5°F increments. Differential from full open to full closed is typically 10° to 15°F. Valve opens/closes gradually.
