PMFL80-3-4,PMFL80-6-7 Danfoss Liquid level regulating valves

For modulating liquid level control in refrigeration,
freezing and air conditioning plant, a system
comprising a liquid level regulating valve type
PMFL or PMFH, controlled by a pilot float valve
type SV, is used.
PMFL and SV systems are used on the evaporator
side. PMFH and SV systems are used on the
condenser side.
The system is suitable for use with ammonia or
fluorinated refrigerants. The PMFL and PMFH can
be used in liquid lines to or from
• evaporators
• separators
• intermediate coolers
• condensers
• receivers
Modulating liquid level regulation provides
liquid injection that is proportional to the
actual capacity. This gives a constant amount
of flashgas, thus ensuring stable regulation and
economic operation because variations in
pressure and temperature are held to a
minimum.
