Sanhua Launches New PEV-S Pulse Expansion Valves Rated for 35 Bar MOPD

Sanhua is advancing its refrigeration solutions with the introduction of new PEV-S Pulse Expansion Valves, now capable of handling a Maximum Operating Pressure Differential (MOPD) of up to 35 bar. Previously, the company’s PEV models were constrained to MOPDs of 30, 25, or 18 bar.

The newly introduced PEV-S series incorporates innovative coil models inspired by the MQ coils from Sanhua's MDF series. These include an enhanced top assembly compatible with the existing PEV body. Additionally, Sanhua has broadened its coil offerings with the MQ-A03 models, featuring standard screw terminals for secure electrical connections, and the MQ-A11 models, which are equipped with lever terminals, allowing for easier, tool-free installation.

The PEV series, specialized for refrigeration systems, utilizes a solenoid valve structure to accurately control refrigerant flow into the evaporator. By using pulse width modulation, these valves enable precise and responsive management of refrigerant flow, enhancing overall system efficiency.

With these new advancements, Sanhua continues to demonstrate its commitment to innovation and efficiency in refrigeration technologies.
