SRI - Top Entry Trunnion Ball Valve
The cover of top-entry ball valve can be disassembled from the body of the valve, so all parts can be easily maintained or replaced in-line. On demand, trem, trunnion and ball can be made as a monobloc piece. This option increases the reliability of the valve. This construction allows more flexibility in customization of driving train design, allowing for example the mounting of an actuator directly on the bonnet without an intermediary bracket.
Engineering & Technologies
SRi uses the latest techniques like CAD, DAO and structural calculations in the conception, verification, analysis and testing of our products.
A permanent research and development program leading to patents means always more reliability and performance in our products.
SRi is equipped with a finite element analysis software ANSYS.
This software can simulate: Thermal, solid mechanics, mechanics of fluid, fluid/structure interaction.
