The Hongsen Thermal Expansion Valve (TXV) is designed for reliable refrigerant flow control in HVAC and refrigeration systems. It regulates the amount of refrigerant entering the evaporator to help maintain stable superheat and efficient system operation. The valve supports a wide range of evaporating temperatures and includes features that improve compressor protection, low-temperature performance, and serviceability.

In addition, the Hongsen thermal expansion valve offers both internal and external equalizer options. This flexibility allows technicians to select the appropriate configuration for different refrigeration system designs. Its durable construction and advanced diaphragm technology also support reliable performance in demanding applications.

Hongsen Thermal Expansion Valve Features

• Wide Operating Temperature Range:
  The valve operates across a wide range of evaporating temperatures, making it suitable for different refrigeration applications.
• MOP Function:
  The Maximum Operating Pressure (MOP) function helps protect the compressor motor by limiting excessive evaporating pressure during system operation.
• Internal and External Equalizer Options:
  The valve is available with internal or external equalizers. These options help reduce the effect of pressure loss across the evaporator.
• Patented Diaphragm Structure:
  The patented diaphragm design improves valve performance, particularly in low-temperature refrigeration applications.
• Double-Sealed Bonnet:
  The double-sealed bonnet design helps minimize external refrigerant leakage and supports reliable long-term operation.
• Filter Orifice:
  The integrated filter orifice makes the valve easier to store, match, replace, and maintain during refrigeration system servicing.
• Mixed Charging Technology:
  The temperature bulb uses mixed charging technology to help maintain a consistent superheat level across the evaporating temperature range.

Applications

The Hongsen Thermal Expansion Valve is suitable for a wide range of refrigeration and HVAC applications. Technicians can use it in refrigeration systems, cold storage equipment, commercial refrigeration units, cooling systems, and other applications that require controlled refrigerant flow and stable evaporator superheat.

With its MOP function, equalizer options, advanced diaphragm structure, and reliable sealing design, the valve provides a practical solution for professional refrigeration system installation, maintenance, and repair.
