Sanhua has published its Standard Product Catalogue, presenting a range of controls and components for commercial refrigeration, air conditioning and heat pump systems. The 356-page publication provides technical specifications, operating parameters, product selection data and application diagrams for HVAC&R professionals.
The catalogue covers electronic expansion valves, pulse expansion valves, thermostatic expansion valves, electronic controllers, pressure sensors, pressure switches and mechanical pressure regulators. It also includes solenoid valves, ball valves, check valves, filter driers, sight glasses, service valves, four-way reversing valves and variable speed drives.
Among the products featured is the PEV series of pulse expansion valves, designed for precise refrigerant flow control in refrigeration systems. The valves have a maximum working pressure of 90 bar (approximately 1,305 psi), support R744 (CO2) and various HFC and HFO refrigerants, and use pulse-width control to regulate flow. The catalogue also presents the SEK series electronic expansion valve kits, which combine SEC controllers with sensors and electrical accessories for superheat control.
The DPF-TS/S series electronic expansion valves are designed for air conditioning, refrigeration and heat pump applications. They support bidirectional refrigerant flow and offer cooling capacities from 2 to 121 kW (approximately 6,824 to 412,900 BTU/h) with R410A. The range is compatible with several refrigerants, including R32, R290, R1234yf and R1234ze(E).
In addition to individual product specifications, the catalogue includes application diagrams for commercial refrigeration installations, VRF air conditioning systems and heat pumps. These illustrate the integration of expansion valves, controllers, pressure sensors and other components into refrigeration and heating circuits.
