027F3068 Danfoss PMFH 80-5 Liquid Level Regulating Valve

For regulating 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.

Features:

• Applicable to HCFC, HFC and R717 (Ammonia)
• PMFL / PMFH are based on PM valve family housings
• Same flange program as for PM valve series
• Valve housing in low temperature cast iron (spherical) - EN GJS 400-18-LT
• Manual operation possible
• Position indicator available
• Pressure gauge connection to monitor inlet pressure

Parts included:

• Blanking plug
• Flange bolts
• Flange gaskets
• Pilot connector
