Hongsen Thermal Expansion Valve For Refrigeration System

Hongsen Thermal Expansion Valve for Refrigeration System The Hongsen Thermal Expansion Valve (TXV) is designed to control refrigerant flow into the evaporator and maintain stable superheat across a wide range of evaporating temperatures. It is suitable for refrigeration systems using R22/R407C, R134a, and R404A refrigerants, with different temperature and capacity ranges depending on the refrigerant. The valve features an MOP function for compressor protection, internal and external equalizer options, and a patented membrane structure for improved low-temperature performance. Its double-sealed bonnet helps minimize external leakage, while the filter orifice simplifies storage, matching, and maintenance. Mixed charging technology helps maintain a consistent superheat degree throughout the evaporating temperature range. Features Wide operating range of evaporating temperatures MOP function helps protect the compressor motor from excessive evaporating pressure Internal and external equalizer options for effective pressure-loss compensation Patented membrane structure for improved low-temperature performance Double-sealed bonnet design to minimize external leakage Filter orifice for easier storage, matching, and maintenance Mixed charging technology for consistent superheat across the evaporating temperature range Technical Parameters Parameter Specification Applicable Refrigerants
