Hongsen QFT Ball Valve

The Hongsen Thermal Expansion Valve (TXV) is a refrigeration system component designed to regulate refrigerant flow into the evaporator and help maintain the required superheat. It supports stable refrigeration performance across a wide range of evaporating temperatures.

With MOP protection, internal and external equalizer options, and a patented low-temperature membrane design, this expansion valve is suitable for refrigeration applications where accurate refrigerant control and reliable operation are important.

Features

• Wide Operating Temperature Range: Operates across a wide range of evaporating temperatures for flexible refrigeration applications.

• MOP Function: Helps protect the compressor motor from damage caused by excessive evaporating pressure.

• Internal & External Equalizer Options: Effectively reduces the impact of evaporator pressure loss and supports accurate refrigerant control.

• Patented Membrane Structure: Enhances valve performance at low evaporating temperatures.

• Double-Sealed Bonnet Design: Minimizes external refrigerant leakage and supports reliable operation.

• Filter Orifice Design: Makes storage, orifice matching, and maintenance easier.

• Consistent Superheat Control: Uses mixed charging technology in the temperature sensing bulb to maintain a consistent superheat degree across the evaporating temperature range.
