LNG Cryogenic Extended Stem Ball Valve
Features & Benefits
1. Low Operating Torque
2. Fireproof Structure Design
3. Anti-static Structure
4. Reliable seat sealing structure
5. Single Sealing (automatic Pressure Relief In Middle Cavity Of Valve)
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.

What Are Trunnion Ball Valves?
The stem of a trunnion ball valve is rigidly attached to the ball, which prevents the ball from moving anywhere except on its axis. Since the ball does not “float” downstream with the pressure of the media, trunnion ball valves can maintain a proper seal on both sides simultaneously. This is especially crucial for multi port valves and valves in very low-pressure applications in which the flow of media is not strong enough to push the ball against its downstream seat.
How do Trunnion Ball Valves Work?
Trunnion ball valve manufacturer designs their trunnion ball valve to work in a way similar to a floating ball valve. The working principle of a trunnion ball valve involves rotating the ball to control fluid or gas flow.
How is a Trunnion Ball Valve Constructed?
The construction method of a trunnion ball valve used in different industrial valve companies involves the assembly of several components, with specific materials are chosen for their properties and suitability for the valve’s intended application.
