Introduction
In critical industrial applications where high pressure, large pipe diameters, and reliable shutoff performance are required, the Trunnion Mounted Ball Valve has become one of the most trusted valve solutions. Its robust construction, low operating torque, and superior sealing capability make it an ideal choice for oil & gas, petrochemical, LNG, offshore, and power generation industries.
Designed and manufactured in accordance with API 6D, API 608, ASME B16.34, ASME B16.5, and related international standards, J-VALVES Trunnion Mounted Ball Valves deliver exceptional reliability and long-term performance in demanding service conditions. With years of engineering experience and advanced manufacturing capabilities, J-VALVES continues to provide high-quality ball valve solutions to customers worldwide.
Key Features of Trunnion Mounted Ball Valves
1. Low Operating Torque
The trunnion-supported ball absorbs the pressure load, minimizing friction between the ball and seats during operation. This results in lower operating torque and allows the use of smaller actuators, reducing overall system costs.
2. Reliable Double Sealing Performance
The spring-loaded seat design ensures tight sealing under both low-pressure and high-pressure conditions. The valve can achieve bidirectional sealing performance, improving operational safety and reducing leakage risks.
3. Excellent Performance in High-Pressure Systems
Designed for pressure classes ranging from ASME Class 150 to Class 2500, trunnion mounted ball valves are widely used in transmission pipelines, refinery units, and offshore production facilities where pressure containment is critical.
4. Fire-Safe Design
J-VALVES Trunnion Mounted Ball Valves can be supplied with fire-safe construction in accordance with API 607 and API 6FA, ensuring emergency sealing capability in the event of a fire.
5. Anti-Static and Blowout-Proof Stem Design
The anti-static device prevents electrostatic discharge during operation, while the blowout-proof stem enhances operational safety by preventing stem ejection under pressure.
6. Double Block and Bleed (DBB) Capability
Many J-VALVES trunnion mounted ball valves are available with Double Block and Bleed functionality, allowing operators to isolate both sides of the valve and safely release cavity pressure for maintenance and inspection.
