High Handle Ball Valve

The Yuanlun High-Stem Ball Valve is a high-performance product developed by Yuanlun Valve for complex media transportation and extreme operating conditions. It features an innovative heightened stem design that enhances operational space and safety redundancy, making it particularly suitable for remote control applications in deeply buried pipelines, elevated installations, and explosion-proof zones. The valve trim incorporates an ultra-wear-resistant hard alloy coating and a composite sealing ring made of flexible graphite and metal, ensuring robust performance in harsh environments such as oil-gas mixed transportation, chemical crystallization, and ore slurry erosion. Certified to API 6D/ISO 15848 standards and compatible with intelligent upgrades, it serves as a reliable solution for petroleum refining, LNG storage and transportation, and mining metallurgy.

1.Material Craftsmanship and Quality Control

• The valve body is made of high-strength alloy steel or corrosion-resistant stainless steel, processed through precision casting and CNC machining to ensure structural integrity.

• The ball surface is coated with a hard alloy layer, and the valve seat uses a composite sealing structure of flexible graphite and metal, maintaining zero leakage after over ten thousand opening and closing cycles under high-pressure, high-temperature, and corrosive conditions.

• Production adheres to the ISO 9001 quality management system, with each valve undergoing helium mass spectrometer leak detection to meet API 6D standards.

2.High-Stem Design Addressing Industry Challenges

• The elongated stem extends 300-800mm from the valve body's centerline, enabling trenchless operation in deeply buried or elevated pipelines and providing standardized mounting space for electric/pneumatic actuators.

• The valve stem features a double-sealed anti-blowout structure and anti-static devices, preventing safety incidents caused by media leakage.

• For extreme environments, the high-stem structure can integrate insulation jackets or electric tracing systems to ensure normal operation under low-temperature conditions.

3.Comprehensive Adaptability

• The valve is available in various structural forms, including full bore, reduced bore, and double seal, with a nominal bore range of DN15-DN1200, pressure ratings from Class 150 to Class 2500, and temperature resistance from -196°C to 650°C.

• In petroleum refining, it withstands harsh environments with H₂S content exceeding 2000ppm, while in LNG receiving stations, ultra-low temperature products pass the -196°C liquid nitrogen impact test, ensuring seals remain intact under extreme conditions.
