Cast Trunnion Ball Valve
Didtek Cast Steel Trunnion mounted ball valves allow easy and smooth operation at high line pressure. Carefully aligned bearings assist low torque operation. The ball is fixed in position but free to turn.
LCB Low Temperature Gearbox Fire Safe Trunnion Ball Valve
Features & Benefits
1. Didtek Ball Valve can be quickly opened and closed with a quarter turn movement
2. Ensure a very tight seal without the need for high torque forces
3. have a compact design (this is the main difference between a ball valve and a gate valve – which are both on/off devices).
4. In a floating valve, the ball is suspended in the flowing fluid and is kept in position by the compression of two elastomeric seats against it.
5. Plant fires are a serious concern for soft-seated ball valves because of possible fluid leakage and consequent increase of the fire magnitude caused by deterioration of resilient sealing materials.
6. The “Full port” (FB) type features a bore size (the hole of the ball) matching the bore size of the connected piping. Full port ball valves minimize the pressure drop that is generated by reduced port valves but they are of course more bulky, heavy and expensive. FB ball valves are better suited, than RB ball valves, for throttling applications.
