Titanium Ball Valve

Valves Only is one of the most reputed Trunnion ball valve manufacturers in USA and provides robust and rugged valve solutions to different industries. 

Trunnion ball valves are the inherent component of flow control systems, particularly those operating under severe pressure and temperature conditions.  Even in the toughest industrial environments, the robust characteristics of these valves guarantee tight shut-off, low leakage, and smooth and silky operation.    

What is Trunnion Ball Valve? 

A trunnion ball valve is a special ball valve where the bottom and top are mechanical anchoring devices trunnioned on the ball.  High-pressure stable operation is supported by this, apart from taking stress off the valve seat.  Trunnion ball valves are tighter-closing and better applicable to large diameter pipes compared to floating ball valves. 

Why is it required? 

• High-Pressure Applications: Maintains high levels of pressure without compromising function. 

• Secure Sealing: Suitable for vital processes because it provides zero leakage assurance. 

• Large bore sizes are ideal for pipelines that are long in diameter. 

• Safety operation mitigates risk and prevents blowouts during hazardous situations.

Key Components of Trunnion Ball Valve: 

• Valve Body: The central housing that houses the internal elements is referred to as the valve body. 

• Trunnion Support: Anchoring the ball, support by trunnion minimizes seat wear and provides stability. 

• Ball: Spherical component for controlling flow. 

• Seats: Push against the ball to provide positive shut-off. 

• Stem and Seals: Allow rotation without leaking. 

• Actuator or Handle: Manually or automatically controls operation of valve.

How a Trunnion Ball Valve Works 

 In order to open or close the flow, the valve turns the ball 90 degrees.  The seats travel to create a seal, but the ball seated on the trunnion remains fixed.  This design even when subjected to high pressure and temperature fluctuations ensures consistent sealing performance. 

Advantages of Using Trunnion Ball Valve:  

• Enhanced Sealing: Ideal for conditions where pressure and temperatures are high. 

• Lower Torque Requirement: Since there is less friction, it is easier to turn. 

• Longer Life: Since to trunnion support, parts undergo less wear. 

• Double Block and Bleed Capability: Having the capability to double block and bleed enhances safety during maintenance. 

• Anti- Blowout: Stem ejection while under pressure is avoided by the anti-blower out configuration.

 Functions of Trunnion Ball Valve:  

• Controls flow of fluid in pipeline systems. 

• Provides a forceful shut-off for leaks. 

• Allows for safe isolation and maintenance. 

• Ensures reliable performance in critical applications.
