SHF-G series four-way reversing valves are applicable for heat pump systems such as central, unitary air conditioners to realize switching between cooling mode and heating mode by changing the flow path of refrigerant. The main body in stainless steel guarantees an increased robustness with a design pressure suitable for all the refrigerant types and the certainly of a lead-free material. A Sanhua patent is related to the bi-metal joint of the four main connections: the pipes material is stainless steel, but the terminal of each connection is in pure copper to allow an easy brazing procedure.

LPF series Electronic Expansion Valves are especially designed for use in refrigeration systems. Thanks to the soft-sealing seat design, it can be as tight as a solenoid valve once it is completely shut off thus to prevent liquid refrigerant migrate to evaporator or compressor.

DPF-R series electronic expansion valves are mainly used in air conditioning systems with variable refrigerant flow to realize automatic adjustment of refrigerant flow rate and make the air conditioning system work under the best working condition for the purpose of fast cooling, precise temperature control and power saving. These valves can also be used for other controls.
These valves are unidirectional which can automatically control the flow of refrigerant.

MPS are mini pressure switches with non-adjustable settings. Due to its low weight and compact size, they are usually directly installed on the refrigeration, air conditioning, heat pump systems for high-pressure, low-pressure protection or for fan control.

The ball valve of series RBV-R is applicable for commercial air conditioner, freezing or deep-freezing equipment or other refrigeration circuits in order to open and to shut off inner flow path by operating the valve stem. It can also be used as service valve for vacuum pumping and refrigerant injection etc.
The Design Pressure (PS) of the versions RBV-R has been increased to 49 bars allowing the usage in R32 systems. Moreover, the use of graphite sealing material guarantees a wide refrigerant temperature range [from -60°C to +160°C], and the possibility to install RBV-R valves in the high temperature discharge line of R32 systems.

All the Solenoid Valves listed in this datasheet can be installed in system using flammable refrigerants HFO (categories A2* and A2L*), and Hydrocarbons HC (category A3*).

Pressure sensors are widely used in Air Conditioning, Refrigeration and Heat Pump system.
YCQB is using a 5 V excitation input these sensors provide a 0.5-3.5 V or 0.5-4.5 V ratiometric signal output proportional to the pressure of the medium.
YCQC pressure sensor uses a DC 10-30V excitation input to provide a 4-20mA signal output proportional to the pressure of the medium. This device requires no end user amplification. Pressure sensors permit to control and guarantee the system working under safe and stability condition.

Sight glasses are installed after the filter drier in liquid line of refrigerating systems, in order to observe property changes of the refrigerant (liquid/vapour) and to indicate the moisture level by colours.
