PMFL80-3-4-5-6-7 Series Flow Control Valve

Product Introduction of PMFL80-3-4-5-6-7 Series Flow Control Valves

Based on the housing of the PM series control valves, the Danfoss PMFH/PMFL series servo-controlled liquid level regulating valve family provides a convenient and reliable solution for refrigerant liquid level regulation in refrigeration and air conditioning systems. As one of Danfoss's precise liquid level control solutions, the mechanical liquid level control method using PMFH/PMFL servo-controlled liquid level regulating valves ensures system stability and high efficiency while delivering cost savings for users.

The Danfoss PMFH/PMFL series servo-controlled liquid level regulating valves offer you:

◈ Unique design that provides refrigerant injection proportional to actual capacity, delivering relatively stable flash gas to the system

◈ Small fluctuations in pressure and temperature, ensuring stable system regulation

◈ Suitable for systems with low refrigerant charge and capable of meeting a wide range of cooling capacity adjustments

◈ Pure mechanical liquid level control solution, more economical and practical

◈ Valve body made of low-temperature ductile iron, suitable for pressure requirements including ammonia and other non-corrosive refrigerants

◈ Zinc-plated surface provides effective rust protection

Main Technical Parameters:

◈ Refrigerant: Suitable for all common non-flammable refrigerants, including ammonia and non-corrosive gases/liquids

◈ Temperature Range: –60℃/+120℃ (–76℉/+248℉)

◈ Maximum Operating Pressure: 28 bar g (406 psi g)
