Free floating drain valve
The Free Floating Drain Valve is an automatic drainage valve designed to remove condensate, water, and liquid impurities from pipelines, compressed air systems, steam equipment, and industrial process systems. It adopts a free floating mechanism that automatically adjusts the valve opening and closing according to the liquid level, providing efficient drainage performance without the need for manual operation or external power.
Free floating drain valve
With a simple structure, high sensitivity, reliable sealing, and low maintenance requirements, this valve effectively prevents liquid accumulation and improves the operational efficiency and safety of pipeline systems. It is suitable for applications where continuous automatic drainage and stable fluid control are required.
We offer comprehensive OEM manufacturing and customization services, including customized valve sizes, body materials, connection standards, pressure ratings, sealing materials, float designs, surface treatments, logo marking, and packaging solutions. Our engineering team can provide customized solutions according to different working conditions and customer requirements.
All products are manufactured under strict quality control procedures and are supplied with complete valve industry certifications, including material certificates, pressure test reports, quality inspection documents, and other compliance certifications required for global markets.
