Trunnion Ball Valves

When it comes to controlling the flow of liquids and gases in high-pressure systems, Trunnion Ball Valves stand out as one of the most reliable and efficient solutions. At Keystone Valve Supply, we provide top-quality trunnion-mounted ball valves suitable for a wide range of industries, from oil and gas to chemical processing. We represent trusted manufacturers, ensuring that you receive durable, high-performance valves tailored to meet your needs.

What are Trunnion Ball Valves?

A Trunnion Ball Valve is a type of ball valve where the ball is supported by trunnions (or support shafts) on both sides of the ball. This design ensures that the valve can withstand high pressures without distortion, making it ideal for applications where the valve will be exposed to extreme conditions. Whether you need a 2-piece, 3pc Full Bore and RB trunnion mounted ball valve, these valves provide a tight seal and can handle a wide range of temperatures and pressures.

Key Features of Trunnion Ball Valves

Trunnion ball valves are designed with durability and efficiency in mind. Here are some of their key features:

• Enhanced Sealing: The trunnion design allows for a stronger and more reliable seal, preventing leakage in high-pressure systems.
• High Pressure Resistance: Trunnion ball valves can handle pressure ratings ranging from ANSI 150 to ANSI 2500, ensuring reliable operation in demanding environments.
• Versatility: Available in NPS 2” – 36” sizes and with stainless steel or carbon steel trim, these valves can be customized for a variety of applications.
• Low Emission Compliance: We offer valves that meet ISO 15848-1 and API 641 Low Emissions standards, making them ideal for industries that require strict environmental compliance.

Types of Trunnion Ball Valves We Supply

At Keystone Valve Supply, we offer a range of trunnion ball valves for different operational needs. These include:

• 2-Piece Trunnion Ball Valves: These valves feature a two-part design, making them more compact and easier to maintain. They are ideal for a variety of medium to high-pressure applications.
• Double Block & Bleed (DB & B): This valve type is designed to provide two separate barriers to isolate a process system. It allows for safer operation by preventing leakage and facilitating easy maintenance.
• Double Isolation and Bleed (DIB-1 &; DIB-2): These variants offer additional isolation and bleed options for more secure operations, ideal for high-risk industries like oil and gas.

Why Choose Trunnion Mounted Ball Valves?

Trunnion mounted ball valves are a popular choice for industries needing reliable and durable flow control solutions. Here’s why:

1. Longer Service Life: The design of trunnion ball valves reduces wear on the valve components, leading to longer-lasting performance.

2. Greater Strength: The trunnion support provides added strength, making these valves capable of handling high pressures and ensuring stability.

3. Reduced Torque: These valves require less torque to operate compared to traditional floating ball valves, which reduces actuator size and costs.

Industries That Benefit from Trunnion Ball Valves

Trunnion ball valves are essential in many sectors. Here are just a few industries that depend on the performance of these valves:

• Oil and Gas: For controlling the flow of oil, gas, and other fluids in pipelines, trunnion mounted ball valves provide reliability and safety.
• Chemical Processing: In chemical plants, these valves help control the flow of chemicals and gases, ensuring safe and efficient production processes.
• Power Generation: Trunnion ball valves are crucial in power plants for controlling high-pressure steam and other fluids.
• Water Treatment: These valves help in regulating water flow in municipal and industrial water treatment plants.

Our Quality Standards

At Keystone Valve Supply, we only represent manufacturers who comply with the highest industry standards, including:

• API 6D: Ensuring the valves meet the most rigorous performance and safety standards for the oil and gas industry.
• API 641: Ensuring low emission levels for valves used in sensitive applications.
• CSA Z245.15: Compliance with Canadian standards for the design and performance of valves used in pipeline systems.

FAQs

1. What is the difference between a trunnion ball valve and a floating ball valve?
Trunnion ball valves are supported by trunnions at both ends, while floating ball valves rely on the pressure of the fluid to hold the ball in place.

2. What does "DB & B" mean in valve terminology?
DB & B stands for Double Block and Bleed, which refers to a valve's ability to isolate a section of the pipeline and bleed off any trapped fluid.

3. What sizes are available for trunnion ball valves?
We offer NPS 2” – 36” sizes to meet various system requirements.

4. What materials are used in trunnion ball valves?
Our trunnion ball valves come in stainless steel and carbon steel materials, with SS trim for enhanced performance and corrosion resistance.

5. Are these valves suitable for high-pressure applications?
Yes, trunnion ball valves can handle pressures from ANSI 150 to ANSI 2500, making them ideal for high-pressure applications.

6. Do you offer low-emission trunnion ball valves?
Yes, we provide valves that meet ISO 15848-1 and API 641 Low Emissions standards for industries requiring environmental compliance.

7. What is the typical lifespan of a trunnion ball valve?
Trunnion ball valves have a longer service life due to their sturdy design, reducing wear and tear compared to traditional valves.

8. Can these valves be customized?
Yes, our trunnion ball valves are highly customizable based on size, material, and pressure rating.
