Danfoss servo control liquid level control valve（PMFL80/125/200 / PMFH300） product introduction
Danfoss ammonia liquid level control device PMFL and PMFH series
Summary: in order to regulate the refrigeration and air conditioning system of the liquid level of liquid refrigerant, danfoss company provides a simple and reliable device. It includes a from SV type float valve control type PMFL or PMFH servo control main expansion valve. PMFL and SV for evaporator side; PMFH and SV for condenser side; (applicable to ammonia refrigeration system) or fluoride PMFL and PMFH refrigerants can be used in the following equipment
For the fluid pipeline:
The evaporator,
The gas-liquid separator
• intercooler
The condenser,
• accumulator
PMFL liquid level regulator can give a refrigerant injection amount, and it is proportional to the actual capacity. This means that the valve provides a relatively stable flash gas. Small fluctuations in pressure and temperature to ensure the stable and economic operation of the adjustment.
Features: s is suitable for various not flammable refrigerant: including ammonia and other non-corrosive gas, liquid working medium (take into account the compatibility of sealing material).
S PMFL/PMFH based on PM family housing
S the same as the PM series valve flange
S body is low temperature ductile iron - EN GJS 400-18 - LT
S can be manual operation
S can provide position indicator
S own interface can be measured inlet pressure gauge
S simple installation
S main valve cover can rotate freely to install, does not affect the function of the valve
Technical parameters: maximum working pressure
PMFL/H: MWP = 28 bar
SV: MWP = 28 bar
The maximum test pressure
PMFL/H: the maximum test pressure = 42 bar
SV: the maximum test pressure = 42 bar
Working temperature:
- + 60 ℃ / 120 ℃
Note:
When the valve is made of GGG - 40.3 and medium temperature is below - 20 ℃
Or the valve material for GG - and medium temperature is lower than 25-10 ℃
, the maximum working pressure for: MWP = 21 bar.
