Liquid level regulating valves
Type PMFL / PMFH and SV

For modulating liquid level control in refrigeration,
freezing and air conditioning plant

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 oat 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
uorinated 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
ashgas, thus ensuring stable regulation and
economic operation because variations in
pressure and temperature are held to a
minimum.

Functions

PMFL

Figure 1: PMFL

When the liquid level inside the oat drops, the oat orice 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
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:

Table 1: Subcooling

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
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 dierence:

Table 4: PMFL

Table 5: PMFL

Figure 2: PMFL function example

The values for spindle turns are an indication for an initial setting only. If a position indicator is used, a more precise
modulation can be achieved when ne 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 eect on the ne tuning and large variations in condensing pressure might call for
readjustment. The subcooling is measured just before the PMFL and the pressure dierence is for the valve only
excluding piping and armatures.

The PMFL can be used together with SV 4 as a pilot valve.

The orices determines the Kv (Cv) value of the pilot and the following table can be used as an initial selection guide:

Table 6: PMFL

The nal choice of orice may vary depending on refrigerant and pressure levels. Smaller pressure levels needs a
bigger orice. Pressure dierence levels below 3 bar (43 psi) need SV 4 – 6 with Ø3 mm orice.

SV oats for PMFL

SV 4 can be used for PMFL low pressure control system. The oat must be connected as shown.

Figure 3: SV oats for PMFL

 NOTE:

Only one inlet connection possible for SV 4.

PMFH

Figure 4: PMFH

If the liquid level inside the SV oat rises, the oat orice opens and relieves pressure through the pilot line to the
top of the PMFH, increasing the pressure, 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:

Table 7: spring set selection

The PMFH can be used together with either SV 1 or 3 with the SV mounted with the bleed valve downwards, refer to
the drawing below. This reverses the opening so that rising oat opens the orice.

Figure 5: PMFH function example

 NOTE:

High pressure oat system (for explanatory purposes only)

SV 1 - 3

SV 1 – 3 oat has 2 dierent 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 open the PMFH valve to a fully open position. This is practical for
service purposes or to conrm if the oat has sucient capacity for the PMFH and the operating conditions.
However, when P-port connection is used it is possible to overll a system due to constant bleeding or unautorised
tampering. In this case, it is advisable to introduce a shut o when the liquid level reaches a preset point. Shut o
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 dierence.

S-port:

The S-port oers the advantage of a preorice which divides the pressure drop and any wear possibility due to
cavitation. S-port connection must be used at high pressure dierences, 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.
