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
