Trunnion Mounted Ball Valve
DescriptionTrunnion Mounted Ball Valve Manufacturer
Asten Controls is the reputed Trunnion Mounted Ball Valve manufacturer and supplier in India. We offer highly versatile Industrial Trunnion Ball Valve that are suitable for use in a variety of critical processes in oil & gas, petrochemicals, power generation, refineries, chemical process and pipeline industries.
Trunnion Mounted Ball Valve is a highly advanced quarter-turn valve that is ideally suited for the application involving high pressure, high flow, and large diameter requirements. As opposed to regular floating ball valves, the ball in a trunnion mounted valve is physically supported on upper and lower trunnions to minimize operating torque. As an established Trunnion Mounted Ball Valve Manufacturer in India, we are engaged in manufacturing highly engineered valves that offer unmatched sealing, strength and safety.

Overview of Trunnion Mounted Ball Valve
The Trunnion Mounted Ball Valve is a type of ball valve, where the ball is mounted in position using trunnion bearings on both ends. This prevents the ball from shifting under line pressure, allowing the seats to effectively seal and reduce operating torque.
As one of the leading Trunnion Ball Valve Manufacturer India, we offer valves that meet international standards and can be used for liquid, gas, hydrocarbons, steam, and many more media in industrial processing applications. These valves find wide application in pipelines and isolation systems where high performance is needed.
Features of Trunnion Mounted Ball Valve
Our Trunnion Ball Valves have state-of-the-art designs with various additional features that ensure safer and reliable operations.
Double Block and Bleed
Many of our Trunnion Mounted Ball Valves are engineered with double block and bleed feature to seal the valve from both upstream and downstream directions and safely discharge the valve cavity during maintenance and inspection.
Lower Operation Torque
Due to trunnion supported ball, there is no friction between ball and seats of the valve. Therefore, our trunnion mounted ball valves have much lower operation torque than floating ball valves.
Capability to Withstand High Pressure
Being one of the top High Pressure Ball Valve Manufacturers, our products have the capability to withstand difficult pressure conditions while maintaining a good sealing capability and strength.
Fire-Safe Construction
Fire-safe construction is helpful in retaining the performance of the valve in situations where high temperatures are encountered. This is because of the use of secondary metal-to-metal seal mechanisms that prevent leaks.
Non-Blowout Stem
Internally locked stem mechanism prevents any possible blow out of the stem under pressure.
Long Service Life
Our high quality materials and construction ensures that there will be no wear of seals which increases its longevity in industrial environment.

Advantages of Trunnion Mounted Ball Valve
Suitable for High-Pressure Applications
These types of ball valves with trunnion support for the ball can handle load efficiently hence they are suitable for high pressure applications.
Guaranteed Shut-Off
Precise design of sealing elements ensures perfect tight shut-off of liquids and gases. It lowers the risks of losing the product and increases process safety.
Less Wear and Lower Maintenance Requirements
The design of supported ball decreases the wear of seals. It results in lower maintenance needs and higher components’ life span.
Ideal for Pipeline Systems
Heavy Duty Ball Valve solutions are widely used in large pipeline systems where high flow capacity, strong structure, and reliable seal are needed.
Higher Level of Operational Safety
Fire safety, advanced sealing technologies, anti-static protection, and blowout-proof stems increase safety of working processes in hazardous areas.

Frequently Asked Questions (FAQ)
Q1. What is a Trunnion Mounted Ball Valve?
A Trunnion Mounted Ball Valve is a quarter-turn valve wherein the ball is held in place by means of an upper and lower trunnion. This type of ball valve reduces operating torque and has a good seal in high-pressure and large diameter applications.
Q2. What is the difference between a Floating and Trunnion Mounted Ball Valve?
In a floating ball valve, the ball moves slightly and is sealed against the downstream seat. In a trunnion mounted valve, the ball is held by trunnions which reduces seating force and operating torque and also works well in high-pressure applications.
Q3. What are the applications of trunnion ball valves?
Trunnion Ball Valves are found in oil and gas pipelines, refineries, petrochemical plants, power plants, chemical processing plants, storage terminals, and other heavy industrial plants that require efficient flow control under high pressure conditions.
Q4. Are trunnion ball valves capable of automation?
Yes. The trunnion mounted ball valves can be installed with pneumatic, electric or hydraulic actuators.
