WCB Flanged Trunnion Split Body Ball Valve With Gearbox

Understanding the rigorous demands of industrial fluid isolation, this trunnion ball valve is manufactured to exact dimensional and performance specifications. The integration of advanced sealing materials and a trunnion-mounted core ensures absolute operational safety and minimal wear over thousands of cycles.

Design Description & Safety Mechanisms

Our trunnion ball valves are engineered with a comprehensive suite of safety features, ensuring absolute operational security in critical environments. The double block and bleed capability allows for simultaneous isolation of both upstream and downstream flow, while the self-cavity pressure relief mechanism automatically vents excess internal pressure to prevent structural damage.

• ✔️ Structure: 2 pieces or 3 pieces body

• ✔️ High shut-off sealing mechanism and low torque operation

• ✔️ Block and bleed function for enhanced operational safety

• ✔️ Self-cavity pressure relief to manage thermal expansion

• ✔️ Fire safe design compliant with rigorous industry standards

• ✔️ Blow out proof stem construction ensuring mechanical integrity

• ✔️ Anti-static design eliminating spark risks in volatile media

• ✔️ Locking device (for lever handle operation) preventing unauthorized adjustments

• ✔️ ISO 5211 actuator mounting for automation readiness

• ✔️ Emergency grease injection (option) for temporary sealing restoration

• ✔️ PN design can be available based on specific pipeline requirements

To ensure engineering compliance and absolute reliability, every single valve undergoes 100% rigorous pressure and leakage testing according to API 598 standards before leaving the facility. We understand the critical nature of project timelines, which is why we maintain an efficient production cycle, securing a 15 to 60-day delivery window depending on project scale. For international transit, each unit is securely anchored and encased in robust, fumigation-free plywood cases. This specialized packaging is designed to withstand the physical demands of long-distance ocean freight, protecting the machined flange faces from moisture, salt air, and impact damage upon arrival.

The Didtek WCB Flanged Trunnion Split Body Ball Valve with Gearbox is widely utilized across heavy-duty industrial sectors, specifically chosen for its superior material properties and reliable fluid isolation capabilities. The robust WCB carbon steel construction ensures long-term operational stability even when exposed to fluctuating temperatures and abrasive media.

• Oil & Gas Midstream: Vital for long-distance oil and gas transmission pipelines, compressor stations, and city gas distribution networks. The trunnion design effortlessly handles immense pipeline pressures while preventing internal leakage, ensuring safe and continuous hydrocarbon transport.

• Water Treatment & Utilities: Deployed in industrial cooling water circuits, municipal water supply systems, and large-scale pumping stations. The anti-corrosive trim options protect the internal mechanisms from continuous moisture exposure, significantly reducing maintenance frequency.

• General Manufacturing: Integral to factory power generation systems, heavy machinery lubrication lines, and non-corrosive fluid control. The precise gearbox operation allows plant engineers to regulate flow rates accurately without risking system disruption.

• Chemical Storage & Transport: Provides secure fluid isolation in bulk chemical marine terminals and vast storage tank farms. The fire-safe and anti-static features are absolutely critical in these volatile environments, preventing catastrophic failures during emergency situations.
