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.
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 orfluorinated 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 inpressure and temperature are held to a minimum.
• 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.

When the liquid level inside the float drops, the float orifice opens. This relieves the higher pressure, ps, acting on the servo piston to the low pressure side causing the PMFL to open. Variations in liquid level will result in variations
The setting spindle, pos. 60, has not been set from factory. It is imperative that the setting spindle is adjusted before the valve is put into operation. The outer spring, pos. 23, is preset and the inner spring, pos. 43, is adjusted when
in pressure over the piston and variation in the amount of liquid injected. It is important to choose the correct spring set when designing the plant. The spring set should be selected from the table below:
turning the spindle. The following tables shows the adjustment of the inner spring in number of turns of the spindle as a function of valve size, spring type and pressure difference:

Design / Function(continued)
The values for spindle turns are an indication foran initial setting only. If a position indicator is used, a more precise modulation can be achieved when fine tuning the valve setting. If the PMFL is not opening fully, the spring tension must be reduced. If the PMFL is operating in a ON / OFF function, the spring tension should be increased. The condenser pressure will have an effect on the fine tuning and large variations in condensing pressure might call for readjustment.The subcooling is measured just before the PMFLand the pressure difference is for the valve onlyexcluding piping and armatures.
The PMFL can be used together with SV 4 as a pilot valve.
The final choice of orifice may vary depending onrefrigerant and pressure levels. Smaller pressurelevels needs a bigger orifice. Pressure differencelevels below 3 bar (43 psi) need SV 4 – 6with Ø3 mm orifice.
PMFL function example
SV 4 can be used for PMFL low pressure control system. The float must be connected as shown. Note: Only one inlet connection possible for SV 4.

PMFH
If the liquid level inside the SV float rises, the floatorifice opens and relieves pressure through thepilot line to the top of the PMFH, increasing thepressure, ps, moving the pushrod downwards and opening the PMFH. The pilot line is connected in the topcover at SI. Override of the pilot signal can be made by using an EVM valve at SII. It is important to choose the correct spring set when designing the plant. The spring set should be selected from the table below:

SV 1 – 3 float has 2 different pilot connections: S-port (series connection with PMFH) or P-port (parallel connection with the PMFH).
P-port:When using the P-port, it is possible to force openthe PMFH valve to a fully open position. This ispractical for service purposes or to confirm if thefloat has sufficient capacity for the PMFH and theoperating conditions. However, when P-portconnection is used it is possible to overfill a system due to constant bleeding or unautorised tampering. In this case, it is advisable to introduce a shut off when the liquid level reaches
a preset point. Shut off can be done via an electrical switch if an EVM valve is mounted in the SII port in the top of the PMFH. It is only advisable to use the P-port at low pressure difference.
S-port:The S-port offers the advantage of a preorificewhich divides the pressure drop and any wearpossibility due to cavitation. S-port connection must be used at high pressure differences, dp > 10 bar (145 psi). The Kv (Cv) value of the SV is higher using P-port than using S-port. A higher P-band can thus be obtained.
