Side Entry Trunnion Ball Valve
Side Entry Trunnion Ball Valve
Side entry trunnion ball valves have a ball that enters the valve body through a flange on the side of the body and is secured to two end supports. This design is typically used to handle high-pressure and large-diameter fluid piping systems and is very common in large-scale applications.

Features And Benefits
Side-mounted fixed ball valves are available in split and three-piece designs, with two floating seats that move under media pressure, and with specific springs at the bottom of the seats to ensure that the two seats fit snugly against the ball, pushing the ball against the seat under media pressure to ensure a tight seal.
Fixed ball valves are equipped with removable seat sealing rings, which are displaced by the pressure of the medium, and only when medium pressure is present, the pressure pushes the seat sealing ring against the ball to ensure a tight seal.
Design Standards And Specifications
Ball valves are designed in strict accordance with international and national standards such as ISO14313, API 6D, BS 5351 and GB/T 19672 to ensure product safety, reliability and high performance.
Structure And Sealing Performance
Ball valves have a simple and compact structure, excellent sealing performance, and can maintain stable sealing even under high pressure and high temperature environments. Small operating torque, easy to use, reduced energy consumption and operating difficulties, is the first choice for efficient fluid control.
Optimized Design For Flow Resistance
Available in both reduced and through-diameter configurations, the flow resistance is extremely low, especially in the through-diameter design, where the flow resistance is close to zero. This design ensures smoother fluid flow, reduces energy loss and improves conveying efficiency.
Emergency Grease Filling
The emergency grease filling structure facilitates quick lubrication and sealing in emergencies and is suitable for high pressure or severe working conditions. This design ensures that the ball valve maintains efficient and stable performance during operation and extends service life.
Center Cavity Automatic Pressure Relief Design
The center cavity of the ball valve has an automatic pressure relief function, when the pipeline pressure is too high, it can automatically release the pressure in the center cavity to prevent equipment damage and improve the safety of the system, especially for high pressure systems.
Independent Ball And Stem Structure
The design of independent ball and stem structure enhances the reliability and stability of the valve. It can effectively reduce stem wear, improve sealing performance and extend the service life of the ball valve.
Low Leakage Packing
Adoption of low leakage packing ensures that the ball valve can still maintain good sealing and prevent fluid leakage even under harsh working conditions, which is suitable for industrial occasions with high requirements for safety and environmental protection.
Multi-protection Design
Provide fireproof, anti-static and anti-stem punch-out designs to improve safety. The fireproof design ensures the structural integrity of the ball valve in a fire environment; the anti-static feature prevents static buildup; and the anti-stem blowout design protects the valve’s internal components from high-pressure damage.
Multiple Seat Configurations
The DBB feature provides a bi-directional seal in the closed position, while the DIB-1 and DIB-2 provide double isolation to ensure greater safety and reliability.
Extendable Stem Design
The valve stem can be extended to meet the requirements of downhole or specialty applications, increasing the flexibility and convenience of valve use. The extended design facilitates operation and maintenance while increasing protection in harsh environments.
