We supply genuine original thermal expansion valves from Emerson, Danfoss, Sporlan, Carel, Saginomiya, SanHua and DunAn. Fully stocked with complete models for various chillers and industrial refrigeration equipment. Adopting mechanical induction throttling without electronic control, it adaptively adjusts refrigerant flow, stabilizes unit operation and avoids common faults. Featuring high durability and low maintenance cost, it is a cost-effective universal core part for routine refrigeration equipment maintenance and replacement.
Covers mainstream refrigeration solenoid valve brands including Danfoss, Emerson, Parker, Castel, Saginomiya, SanHua and DunAn, applicable to chillers, central air conditioners and industrial refrigeration systems. With sensitive switching and reliable sealing, it accurately controls pipeline on-off, avoids backflow and liquid hammer, and ensures stable unit operation.
Covers mainstream three-way valve brands including Honeywell, Siemens, Johnson, Belimo, Danfoss, SanHua and DunAn, suitable for HVAC systems and chiller water circuits. It delivers precise flow and direction adjustment to realize constant temperature control and hydraulic bypass stabilization, serving as common basic control parts for building air conditioning and industrial process systems.
Covers mainstream four-way reversing valve brands including SanHua, DunAn, Lanco and Fujikoki, applicable to heat pumps and central air conditioning systems. Featuring smooth reversing, high pressure resistance and stable performance, it reliably switches between cooling and heating cycles for seasonal mode conversion, acting as an essential basic reversing component for HVAC heat pump systems.
Covers mainstream volume control damper brands including TROX, Belimo, Honeywell, Siemens, JOHNSON, COMIFO and KINFLARE, suitable for ventilation and HVAC systems. Featuring precise airflow regulation, flexible control, easy installation, corrosion resistance and long service life, it optimizes indoor air circulation and serves as a universal basic control part for building ventilation and air handling systems.
