Inverted bucket drain valve
The Inverted Bucket Drain Valve is a mechanical steam trap designed to automatically discharge condensate, air, and non-condensable gases from steam systems while preventing the loss of live steam. It operates through an inverted bucket mechanism that responds to changes in condensate level and steam pressure, ensuring reliable drainage and efficient energy utilization.
Inverted bucket drain valve
This valve features excellent resistance to water hammer, stable operation under fluctuating pressure conditions, strong sealing performance, and long service life. It is widely used in steam pipelines, heating systems, industrial process equipment, and applications requiring continuous condensate removal.
We provide professional OEM manufacturing and customization services, including customized valve sizes, pressure ratings, connection standards, body materials, internal components, sealing materials, surface treatments, logo marking, and packaging solutions. Our engineering team can develop customized solutions according to different steam conditions, installation requirements, and customer specifications.
All products are manufactured according to strict quality management procedures and are supplied with complete valve industry certifications, including material certificates, pressure testing reports, quality inspection documents, and other compliance certifications required for international markets.
