Product Overview

A trunnion ball valve is a quarter-turn valve designed for efficient flow control in pipelines. Unlike floating ball valves, it features a fixed ball supported by trunnions at both ends, ensuring stability under high-pressure conditions. This design allows for precise operation with lower torque requirements, making it suitable for large-scale and high-pressure applications. The valve’s construction includes spring-loaded seats that maintain a tight seal across a range of pressures, enhancing reliability and performance. Trunnion ball valves are commonly used in industries such as oil and gas, petrochemicals, and power generation, where dependable shut-off and flow control are critical.

Product Features

• Trunnion Mounted Design:

Ensures stable operation under high pressure, minimizing torque and enhancing sealing performance.

• Forged Construction:

Offers higher strength and durability for critical applications

• Multi-Way Configurations:

Available in three-way and four-way configurations for complex flow paths, ideal for process industries.

• High-Temperature and High-Pressure Capabilities:

Specifically designed for severe conditions, available in high-temperature and high-pressure models

• Compact and Sanitary Designs:

Available for cleanroom, pharmaceutical, and food industry applications
