Lever floating ball type drain valve
The Lever Floating Ball Type Drain Valve is an automatic drainage valve designed to remove condensate, water, and liquid impurities from industrial pipelines, compressed air systems, steam equipment, and process systems. It adopts a lever-operated floating ball mechanism that automatically controls the opening and closing of the valve according to liquid level changes, providing continuous and efficient drainage performance.
Lever floating ball type drain valve
With a simple mechanical structure, high sensitivity, reliable sealing, and stable operation, this valve effectively prevents liquid accumulation and improves the efficiency and safety of pipeline systems. It is suitable for applications requiring automatic drainage without external power supply.
We provide professional OEM manufacturing and customization services, including customized valve sizes, body materials, connection standards, pressure ratings, float ball and lever designs, sealing materials, drainage capacity, surface treatments, logo marking, and packaging solutions. Our engineering team can develop customized products according to customer drawings, operating conditions, and special application requirements.
All products are manufactured under strict quality management systems and are supplied with complete valve industry certifications, including material certificates, pressure test reports, quality inspection documents, and other compliance certifications required for international markets.
