Order specification
The fully welded trunnion ball valve combines the robustness of a fully welded ball valve with the stability of a trunnion ball valve. Its core advantages lie in zero leakage, long service life, and bidirectional sealing, making it particularly suitable for harsh conditions involving high pressure, high temperature, or corrosive media.
Its advantages are outstanding:
Excellent Sealing: Utilizing PTFE sealing rings and spring-loaded seats, it automatically compensates for wear, achieving true zero leakage.
Stable and Durable: The trunnion design ensures more stable ball rotation, reducing friction. Combined with high-precision machining, its service life far exceeds that of ordinary ball valves.
Flexible Operation: Switching requires only a 90° rotation, supporting remote control and automation.
Low Maintenance Costs: Designed to be maintenance-free, reducing the hassle and cost of daily maintenance.
Applications are mainly concentrated in critical areas requiring high reliability:
Energy Industry: Core control equipment for long-distance oil and gas pipelines.
Chemical Production: Used for precise control of corrosive, high-temperature, and high-pressure media.
Urban Infrastructure: Safety shut-off and flow regulation for gas, water, and heating systems.
