Middleeast valve is one of the best Trunnion ball valve suppliers in Dubai. We deliver to cities such as Hatta, Zayed, and AI Aweer.

A trunnion ball valve is a valve which, instead of using ball-shaped objects that produce fluid control, uses a spherical ball and the trunnion types both at the top and the bottom. When compared to the floating ball valve, it enhances the high-pressure and larger sizes capabilities of the trunnion type ball valve.

In an open position, the ball will rotate to provide an open flow path for fluids, while in a closed position, it rotates 90 degrees to seal the flow path. Also, it's done with a trunnion support that minimizes friction wear and tear, allowing for a reliable seal and minimizing the possibility of leaks. Such characteristics lend themselves to wide application in oil and gas, water treatment, and chemical processing situations where high performance under most demanding conditions may be required.

What is the difference between a trunnion ball valve and a floating ball valve?

The difference between the two types of ball valves- trunnion ball valves and floating ball valves-can be clearly seen in the way the ball is supported and the manner in which it functions. Here, in a trunnion ball valve, the ball is at the two ends supported with trunnions that allow it to rotate without disturbing the vertical position. With such design, the sizes of larger sizes and higher-pressure sizes can be more effectively met, the valve being an application-friendly one.

The other, named floating ball valve, has its ball not held in place; it floats between two seats and can move about slightly, sealing when force is applied. Floating ball valves are generally more compact and suitable for applications of lower pressure, but the trunnion ball valves have an enhanced durability and reliability even in harsh conditions of high pressure. Because of this, trunnion ball valves are widely preferred in oil and gas industries, while floating ball valves find much of their application in lighter applications.

Benefits of Trunnion ball valve:

Low Torque Operation: The fixed design with a ball minimizes the amount of torque needed to open the valve. This makes it easier to open and close, especially in larger sizes.

Less Wear on Seats: The design causes less motion of the ball when the valve operates, so the seats show less wear. The service life will be longer, and the maintenance cost will be less.

High Pressure and Temperature Resistance: Trunnion ball valves are designed to handle high pressures and temperatures, making them a versatile option in many industrial applications, including oil and gas.

Good Sealing Performance: They have excellent sealing capabilities that offer a tight shut-off with little leakage-the system integrity and security being improved, therefore.

Bidirectional Flow Capability: Trunnion ball valves can effectively control flow in both directions, which adds versatility to their application.

Compact Design: Their design often brings about a smaller footprint for installations compared to other valves types which makes them more space-efficient in piping.

Key Components:

Ball: The central component, typically made of durable materials such as stainless steel or other alloys, ensures effective sealing and control of fluid flow.

Trunnions: Positioned at the top and bottom of the ball, trunnions provide pivotal support, allowing for controlled rotation and reliable performance over extended periods.

Seats and Seals: The valve's sealing mechanism is critical for preventing leakage. High-quality seats and seals, often made of resilient materials like PTFE or metal, ensure a tight seal even under challenging conditions.

Actuators: Trunnion ball valves can be operated manually or through automated systems using actuators. Actuators facilitate remote control, making these valves suitable for a wide range of industrial applications.

Trunnion ball valve suppliers in Dubai place utmost importance on ensuring the stability and accurate positioning of the ball, particularly under conditions involving high pressures and rapid flow rates, thereby prioritizing operational reliability and precision alignment.
