Sanhua EGH-20M039 Thermal Expansion Valve with Integrated Solenoid

The Sanhua EGH-20M039 Thermal Expansion Valve with Integrated Solenoid is a highly specialized automotive climate control component designed for complex thermal management systems. Manufactured by Sanhua Automotive (a leading global supplier of EV thermal management solutions), this unique valve combines the mechanical flow regulation of a traditional block-type Thermal Expansion Valve (TXV) with the electronic isolation capabilities of a 12V solenoid shut-off valve.

Key Specifications:

• Category: Automotive Parts & Accessories / Engine Cooling & Climate Control / A/C Expansion Valves

• Product Type: Block-Type Thermal Expansion Valve (TXV) with Solenoid Shut-Off

• Manufacturer: Sanhua Automotive

• Model / Part Number: EGH-20M039

• Customer Reference P/N: XZ3101

• Electrical Connection: 2-Pin sealed automotive receptacle (For Solenoid Coil)

• Operating Voltage (Coil): 12V DC

• Body Material: Precision-machined aluminum block

• Actuation Type: Mechanical thermal power element (diaphragm) + Electronic solenoid flow control

Key Features:

• Dual-Function Design – The metallic diaphragm (power element) mechanically senses temperature and pressure to precisely meter the spray of liquid refrigerant into the evaporator. Meanwhile, the black electronic solenoid coil allows the vehicle's ECU to completely shut off refrigerant flow to this specific circuit when cooling is no longer needed.

• EV Thermal Management Ready – This style of shut-off TXV is critical in modern Electric Vehicles (EVs) that feature multiple cooling zones. It allows the vehicle to isolate the cabin A/C evaporator while continuing to route refrigerant to the high-voltage battery chiller, or vice versa.

• Serviceable Solenoid Coil – The black 12V electronic coil is secured to the aluminum valve body with a heavy-duty metal retaining clip. This allows the coil to be easily removed, rotated, or replaced without having to evacuate the A/C system refrigerant.

• Precision Machined Block – The heavy-duty aluminum block features smoothly machined inlet and outlet ports designed to accept standard automotive A/C O-ring pipe fittings for a leak-proof seal.

Ideal For:

• Modern Electric Vehicles (EVs) and Hybrids utilizing independent battery chilling circuits

• Multi-zone automotive climate control systems (e.g., vehicles with separate front and rear A/C evaporators)

• Custom EV conversions where advanced thermal management and refrigerant routing is required

• Direct OEM replacement for failing A/C expansion valves with matching Sanhua part numbers
