Lower operating torque compared to floating ball design
Available in flanged end and butt weld end configurations
Designed for critical shut-off duty and severe industrial service
MNC VALVES LIMITEDΒ is a trusted manufacturer and supplier of Trunnion Mounted Ball Valves developed for heavy-duty industrial service where higher pressure, larger sizes, severe operating conditions, and dependable shut-off are critical. These valves are selected in applications where stronger internal support and lower operating torque are important design priorities.
Trunnion mounted ball valves are widely used in oil & gas, power, process, pipeline, chemical, and industrial utility systems. Their supported ball design provides better load distribution and more stable operation in demanding pressure conditions compared to standard floating ball designs.
AΒ Trunnion Mounted Ball ValveΒ is a ball valve in which the ball is mechanically anchored by upper and lower trunnions instead of floating freely. This supported arrangement helps reduce the operating load on the seats and allows the valve to perform more effectively in higher pressure and larger size applications.
This valve category is commonly selected where the buyer needs high pressure shut-off, stable ball support, lower operating torque, longer seat life, and dependable sealing in critical industrial services.
The ball is supported by trunnions, improving stability and reducing seat loading under pressure.
Suitable for larger sizes and high pressure industrial service conditions.
Helps improve operational efficiency in severe duty applications compared to floating ball types.

It is a ball valve in which the ball is mechanically supported by upper and lower trunnions for better stability and lower torque in demanding service.
It is used to reduce operating torque and improve performance in high pressure and larger size valve applications.
A practical range for this product page is 50 mm to 600 mm.
150#, 300#, 600# and above as required depending on project and service conditions.
Flanged end and butt weld end configurations are commonly used.
The main advantage is better suitability for high pressure and large size applications with lower operating torque.
Yes, it is widely used in oil & gas and critical pipeline-related applications.
WCB, CF8, CF8M, and other alloy grades may be selected depending on the media and project requirement.
PTFE, RPTFE, PEEK, and metal seat arrangements can be used depending on service severity.
Yes, with suitable stainless steel or alloy material selection and proper seat configuration.
Yes, gear, pneumatic, electric, and hydraulic actuation options can be provided depending on the application.
Testing may be carried out as per API 598 and API 6D depending on valve type and project specification.
High pressure, larger size, severe duty, and critical shut-off applications justify this design.
Yes, generally it is a more engineered and higher-cost solution because of its heavy-duty design.
It reduces stress on the seats and improves operational stability under demanding line pressure.
Yes, this design is specifically well suited for larger sizes compared with standard floating ball valves.
Periodic inspection of seats, seals, ball surface, stem arrangement, and actuator or gear performance is recommended.
Yes, it is suitable for critical shut-off duty in utility and high-duty industrial systems.
