Safety filling valve series

The Safety filling valve series is a safety control component during media filling. It precisely controls filling pressure and flow, and features built-in overpressure protection and backflow prevention to eliminate the risk of media leakage or overpressure, ensuring safe filling operations.
It is suitable for filling refrigerants, lubricants, and chemical media, meeting the needs of air conditioners, refrigeration units, and industrial equipment.
Manufactured with corrosion-resistant sealing materials and tested for pressure resistance and sealing, it ensures reliable performance and long service life.
Service includes pre-sales selection and installation guidance. Its advantages include comprehensive safety protection, precise flow control, wide compatibility, and easy operation.
The Safety filling valve series is a core safety control component for media filling operations. Its core advantages are "comprehensive protection + precise flow control." It utilizes a corrosion-resistant, high-strength brass or stainless steel body and incorporates a triple safety mechanism: an automatic overpressure relief valve, a one-way backflow prevention valve (to prevent backflow of media into the source tank), and a valve core anti-leakage gasket. These valves comprehensively mitigate risks such as overpressure, leakage, and backflow, ensuring operational safety. Its core selling points directly address diverse filling needs: it is compatible with a variety of media, including refrigerants, lubricants, and chemical solvents, allowing for switching between them without changing the valve body. An integrated precision flow adjustment knob allows for on-demand setting of the filling volume, preventing waste or insufficient media. The interface utilizes a standardized quick-connect design, compatible with mainstream connectors such as G1/2 and 1/4SAE, eliminating the need for additional adapters and facilitating easy installation and operation. Applications encompass a wide range of areas, including refrigerant filling for air conditioning/refrigeration units, lubricant replenishment for industrial equipment, transfer of corrosive media in chemical production, and automotive brake fluid/coolant filling. Whether it's precise filling in professional maintenance scenarios or bulk media delivery in industrial production, it effectively provides safety control, ensuring both operational safety and efficiency.
