Buried type heat ball valve (short form)
The Buried Type Heat Ball Valve (Short Form) is a compact and reliable valve solution specially designed for underground heating pipeline systems. Featuring a short structural design, excellent sealing performance, and high-temperature resistance, this valve is ideal for applications where installation space is limited and long-term underground operation is required.
Designed for thermal energy transmission systems, the valve provides efficient flow control, reliable shut-off, and excellent resistance to temperature fluctuations. Its compact buried structure reduces installation space requirements while maintaining strong mechanical performance and operational safety.
The valve is manufactured with high-quality materials and advanced processing technology to ensure durability, corrosion resistance, and stable performance in underground environments. It is widely used in district heating networks, hot water systems, thermal pipelines, and industrial heating projects.
We provide professional OEM and customization services to meet various project requirements, including customized valve dimensions, materials, pressure ratings, connection types, stem lengths, sealing structures, coatings, and operating solutions.
All products are manufactured under strict quality management systems and comply with international valve industry standards. We provide complete certifications, including ISO 9001, API, CE, ASME, and other applicable valve industry certifications, ensuring reliable quality and global application compatibility.
