Description
  • Simple, inexpensive, reliable
  • One valve can be employed for all refrigerants. It has an adjustment range of 5"HG to 90 psig
  • Optional bypass bleeds provide complete system unloading when a machine is de-energized
  • Maintains constant evaporator pressure under all load conditions
  • Provides freeze-up protection on a/c systems by keeping the evaporator above the freezing point at low loads
  • Automatically protects against motor overloads during system start-up
  • Permits use of low starting torque motors
  • Protects against overloads caused by high amperage draw by maintaining constant suction even at high (ambient conditions) head pressure
  • Balanced port design maintains steady outlet pressure regardless of changing inlet (condenser) pressure
  • Large equalizer passageway insures that oil won't affect diaphragm operation under low loads and when valve is mounted upside down
  • Constant pressure valves are U.L. & C.S.A. approved
  • Not Rated for use with R410A
  • UL recognized for maximum operating pressure 500 PIS, 400 PSI low site
