Danfoss PMFL80-3-4-5-6-7 level regulating valve

Danfoss PMFL80-3-4-5-6-7 level regulating valve Product introduction

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.

Features • Applicable to HCFC, HFC and R717 (Ammonia).  • PMFL / PMFH are based on PM valve family  housings. • Same flange programme 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.• Simple installation. • Main valve top cover can be located in any position without affecting the function. • Classification: DNV, CRN, BV, EAC etc.  To get an updated list of certification on the  products please contact your local Danfoss  Sales Company.
