1. What Is 2PC Trunnion Ball Valve and Its Applications
The 2PC trunnion mounted ball valve is a core shut-off device widely used in oil, natural gas, coal chemical and high-pressure industrial pipelines. Compared with floating ball valves, it features high pressure resistance, stable tightness and long service life, which is very suitable for large-bore and long-term continuous operation working conditions.
The 16” 300LB WCB 2PC trunnion ball valve is our hot-selling model for overseas projects. Made of WCB carbon steel, it complies with API 6D and ASME standards, adapting to most industrial media and high-pressure pipeline systems.
2. Core Advantages of J-VALVES 2PC Trunnion Ball Valve
Complete In-house Production & Strict Quality Control
Different from ordinary factories that only assemble valves with outsourced parts, J-VALVES owns full production lines including casting, CNC machining, assembly and testing. Every WCB valve passes NDT inspection, hydrostatic test and air tightness test to ensure zero defect and stable quality.
Full International Certificates for Global Projects
All 2PC trunnion ball valves are certified with API 6D, ISO9001, CE and fire safety certificates, fully meeting the tender and acceptance standards of Middle East, Southeast Asia, America and other global engineering projects.
Fast Delivery & High Cost Performance
Imported large-bore high-pressure ball valves have high prices and long lead times up to 3-4 months. With domestic factory advantages, J-VALVES keeps stock of semi-finished 16” and 20” 300LB valves. Bulk orders can be delivered within 45 days. The total procurement cost is 35%-50% lower than imported valves, with fast after-sales spare parts support.
Custom Solution for Complex Working Conditions
We support customized materials (WCB, stainless steel, duplex steel, low-temperature steel), flange types (RF/RTJ) and actuators (electric, pneumatic, hydraulic), adapting to high temperature, high pressure and corrosive industrial environments.
3. Verified Overseas Successful Project Case
Southeast Asia Cross-border Natural Gas Pipeline Project
This overseas gas pipeline project required 16-inch Class 300 large-bore shut-off valves with strict standards for tightness, certification and anti-corrosion performance. Due to the high price and 120-day long lead time of imported valves, the client finally chose J-VALVES and purchased 28 sets of 16” 300LB WCB 2PC trunnion ball valves.
All valves were manufactured strictly in accordance with API 6D standards, with NDT inspection, high-level tightness test and thick anti-corrosion coating. We completed SGS third-party inspection, production and ocean shipment within 42 days, greatly shortening the project cycle.
After official operation, the valves have run stably for a long time under humid and temperature-changing outdoor conditions without leakage or failure. The client placed a repeated order for the second-phase pipeline project, which fully proves the reliable quality of J-VALVES Chinese trunnion ball valves.
Up to now, our 2PC trunnion ball valves have been widely used in Middle East refineries, coal chemical plants and power plant pipelines, exported to more than 30 countries with rich industrial application experience.
