High-Quality Trunnion Mounted Ball Valve
Factories & Manufacturers serving the Mexico market

Jiangsu Shoulong Valve Co., Ltd. (SLVCN) is a world-class designer and manufacturer of high-performance forged steel ball valves. With over 30 years of manufacturing expertise, we have become a trusted supplier for the Mexican market, providing critical flow control components for PEMEX, CFE projects, and private energy developers. We specialize in extreme working conditions including high pressure, high temperature, and cryogenic environments, providing safe and reliable flow control solutions for global industrial projects where operational reliability is non-negotiable.

As Mexico continues to modernize its energy infrastructure—from the Dos Bocas refinery to the expansion of natural gas pipelines across the Bajío and Northern regions—the demand for API 6D certified trunnion mounted ball valves has reached an all-time high. SLVCN is uniquely positioned to meet this demand with high-density forged valves that outperform traditional cast alternatives in durability and safety.

Our core product range covers forged trunnion-mounted and floating ball valves, top-entry and side-entry ball valves, fully welded ball valves, metal seated ball valves, cryogenic ball valves, high-pressure ball valves up to Class 2500 (PN420) and customized higher pressure ratings, as well as high-temperature service valves. Compared with conventional cast valves, SLVCN forged valves feature higher material density, superior mechanical strength, improved resistance to pressure fluctuations and thermal shock, and significantly longer service life under severe service conditions.

For the Mexican market, we emphasize our Double Block and Bleed (DBB) structures and fire-safe designs (API 607 / API 6FA). These features are essential for the safety-conscious environment of modern Mexican petrochemical facilities, where preventing environmental leakage and ensuring worker safety are top priorities.

Safety and reliability are embedded in every design. Our forged ball valves are equipped with Double Block and Bleed (DBB) structures, anti-blowout stems, fire-safe designs in accordance with API 607 / API 6FA, anti-static devices, emergency sealing systems, and pressure-balanced seating structures suitable for high differential pressure operation. Valves can be designed with SPE or DPE seat configurations based on application requirements. For sour service environments, materials and sealing systems comply with NACE MR0175 / ISO 15156 requirements.

To ensure consistent quality, each valve undergoes a complete series of inspections and performance tests in accordance with API 6D, API 598, and ISO 5208, including shell test, seat leakage test (Rate A / zero visible leakage), fire-safe test, cryogenic test, operational torque test, dimensional inspection, and PMI material verification. SLVCN operates dedicated cryogenic testing facilities to validate valve performance at ultra-low temperatures down to −196°C.
