Product Description

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.

Payment Terms︰ TT
