Valvae

Hebei Yongqian Trading Co., Ltd specializes in manufacturing high-performance air release valves that optimize pipeline operations across various industries. Our valves are precision-engineered to automatically release accumulated air pockets from pressurized water systems, preventing flow restrictions, water hammer, and corrosion damage.

Designed for both vertical and horizontal installations, these critical components maintain peak system efficiency in municipal water networks, irrigation systems, and industrial piping configurations. The robust stainless steel construction ensures reliable operation even in high-pressure environments up to 25 bar, while the precision-machined components deliver consistent performance cycle after cycle.

Advanced Air Release Valve Technology for Complex Systems

Our air release valves incorporate innovative engineering solutions to address modern pipeline challenges. The large-orifice design allows rapid air expulsion during system filling, while the precision float mechanism provides sensitive microbubble release during normal operation. Specialized models feature dual-chamber configurations for critical applications where uninterrupted operation is paramount.

The corrosion-resistant internals, including stainless steel floats and nitrile rubber seals, withstand aggressive water conditions and extended service intervals. These technological advancements make our valves ideal for HVAC systems, wastewater treatment plants, and high-rise building water supply networks where air accumulation can cause serious operational issues.

Durable Construction of Air Release Valves for Harsh Environments

The exceptional durability of our air release valves stems from meticulous material selection and manufacturing processes. The valve bodies are cast from high-grade ductile iron with optional epoxy coating for corrosive environments, while marine-grade stainless steel components resist pitting and scaling. We utilize CNC-machined seating surfaces that maintain perfect seal integrity even after thousands of operating cycles.

For extreme conditions, we offer specialized models with reinforced construction capable of handling temperatures from -10°C to 120°C and pressures up to 40 bar. These construction features ensure reliable performance in challenging applications including geothermal systems, industrial process piping, and coastal area installations where saltwater exposure is a concern.

Customizable Air Release Valve Solutions for Specialized Applications

Understanding that every piping system has unique requirements, we provide air release valves with extensive customization options. Our engineering team can modify orifice sizes, pressure ratings, and connection types to match specific project specifications. Special configurations include combination air valves that integrate air release and vacuum break functions, and large-capacity valves for major transmission mains.

We offer various end connections including flanged, threaded, and grooved options to simplify installation. For visually sensitive locations, we provide decorative enclosures that maintain architectural aesthetics while ensuring proper valve function. These tailored solutions have been successfully implemented in landmark projects including high-elevation water supply systems, industrial cooling circuits, and fire protection networks.
