TRUNNION SOFT SEATED BALL VALVES
INDUSTRIAL BALL VALVES
Trunnion mounted ball valves work the same way as floating ball valves, but in this case the ball is anchored by a second shaft at the bottom of the shutter, called trunnion. This prevents the ball from moving from its axis. trunnion mounted ball valves can keep proper sealing on both sides at once. This is suitable for 3- or 4-way valves and valves in very low pressure applications where the flow is not enough to push the ball into its seat downstream.
These valves are effective in low and high pressure applications, and require less torque than floating ball valves.
Soft Seated
Soft seat valves have sealing surfaces made of non-metallic thermoplastic materials such as PTFE, Nylon, PEEK and others… They work for temperatures below 270°C (depends on sealing material). Under the right conditions, soft seat valves can offer a very high level of sealing throughout their service life, usually more than a conventional metal valve.
However, soft seat valves are not a good combination for corrosive media, dirty or abrasive process fluids. These conditions can cause the soft seat to break and leak They cannot withstand the same pressures as metal valves. Although soft seat valves are often less expensive than metal seat valves, metal seat valves are usually more suitable when severe service is required.
