Future-proof your operations with Intervalve’s Trunnion-Mounted Ball Valves.
Our trunnion-mounted ball valves feature a sturdy trunnion design that ensures stability and durability under high-pressure conditions. The trunnion acts as a support structure, improving the valve’s strength and allowing for smooth, low-torque operation. This design secures a positive seal on both downstream and upstream seats, regardless of pressure, enabling Double Block and Bleed (DBB) or Double Isolation and Bleed (DIB) functionality.
The IV range of trunnion-mounted ball valves, available with a soft-seated seat design, incorporates various unique design features to provide rugged construction, reliable operation, and a long service life. These valves are suitable for a wide range of applications, from standard to the most demanding, across various process industries such as oil & gas, chemical, petrochemical, pharma, steel, power plants, hydrocarbon services, common utilities, and allied sectors, including midstream and downstream applications.
Soft seats are available in various materials such as PTFE/GFT/CFT/CTPFE/PEEK/DEVLON to meet pressure-temperature application requirements.
Ideal for flow isolation and ON/OFF duty, these valves provide a positive shut-off of fluids and gases under various service conditions.
They are available in a comprehensive range of designs, materials, sizes, and pressure classes, fully conforming to international specifications. The ball valves are designed according to ASME B16.34 and API 6D standards.
All Trunnion Mounted Ball Valves, whether soft-seated or metal-seated, come with double body and multiple stem seals to ensure reliable sealing.
As per client requirements, the valves can have special features like extended stem/bonnet extension, drain and vent arrangements, emergency sealant injection, and fire-safe construction.
