6 Inch 6000LB 2Pcs WCB Trunnion Mounted Ball Valve - Ball Material: F304, Seat Material: DEVLON

When it comes to oil and gas applications, our trunnion-mounted ball valves are essential for enhanced performance and reliability. Designed by Henlem, a leading manufacturer and supplier in China, these valves minimize friction between the ball and seat while effectively absorbing line pressure. This design feature significantly reduces torque requirements, even in high-pressure environments. Our valves utilize an extensive range of approved materials that not only improve performance in corrosive situations but also resist sulfide stress cracking, ensuring longevity and durability.

As a trusted factory, Henlem produces both three-piece and two-piece trunnion ball valves, adhering to the highest engineering and manufacturing standards. Our comprehensive range of valves is equipped with advanced features such as self-cavity pressure relief seats, secondary sealant injections, fire safety designs, anti-blowout stems, and double block and bleed (DBB) capabilities. These attributes make our ball valves among the most sought-after in the industry.

Additionally, our products are designed for easy field servicing. We offer a wide array of options, including locking devices and stem extensions, compatible with all our valves, transition pieces, and direct-mounted actuation. Trust Henlem for quality ball valves that excel in the most demanding applications.

Feature

1. Trunnion Design

The ball is fixed in place by a trunnion (a shaft or pin) at the top and bottom, which reduces the load on the valve seats and ensures stable operation.
2. Low Operating Torque

The trunnion design reduces the friction between the ball and the seats, requiring less force to operate the valve. This is especially beneficial in high-pressure applications.
3. Double Block and Bleed (DBB) Capability

Trunnion mounted ball valves can isolate both upstream and downstream sides of the valve simultaneously, allowing for the bleeding of pressure or fluid from the cavity between the seats.
4. Sealing Performance

The design provides better sealing performance, as the seats are spring-loaded or activated by the line pressure to maintain a tight seal.
5. Safety and Reliability

These valves are known for their high reliability and are often used in critical applications like oil and gas, petrochemical, and power industries.
6. Size and Pressure Handling

Suitable for larger diameters and high-pressure conditions, trunnion mounted ball valves can handle a wide range of pressures and temperatures.
7. Bi-Directional Operation

These valves can control the flow of fluid in both directions, providing flexibility in various piping configurations.
8. Extended Service Life

The reduced wear and tear on the seats due to the trunnion support leads to a longer service life and lower maintenance costs.
9. Emergency Sealant Injection System

Many trunnion mounted ball valves have an emergency sealant injection system that allows for sealing in case of seat damage.
10. Fire-Safe Design

Many trunnion mounted ball valves are designed to be fire-safe, ensuring operation even under fire conditions to prevent leakage and maintain control.

These features make trunnion mounted ball valves a preferred choice for demanding applications where durability, reliability, and performance are critical.

Application

Trunnion mounted ball valves are versatile and reliable, making them ideal for a variety of applications requiring high pressures, large diameters and reliable sealing. Here are some key applications:

1. Oil and Gas Industry

• Upstream: Used in drilling operations, production manifolds and wellhead equipment.
• Midstream: Ideal for piping systems, storage facilities and compressor stations.
• Downstream: Commonly used in refineries and petrochemical plants to control process flows.
2. Petrochemical Industry

Critical to the transport and processing of chemicals, a strong and reliable seal is essential.
3. Power Generation

Used in power plants, including nuclear, thermal and hydropower plants, to control steam, water and other fluids in high-pressure systems.
4. Water and Wastewater Treatment

Used in large water treatment plants and distribution systems due to its durability and ability to handle high pressures.
5. Marine and Offshore Applications

Suitable for subsea applications and offshore platforms where reliability under extreme conditions is critical.
6. Liquefied Natural Gas and Cryogenics

Ideal for liquefied natural gas (LNG) plants and cryogenic processes due to its performance at low temperatures.
7. Mining and Mineral Processing

Used in slurry handling, ore processing and other high wear environments.
8. Pulp and Paper Industry

Used in the processing and transportation of pulp and paper products, often requiring large volumes and high pressures.
9. HVAC System

Heating, ventilation and air conditioning systems for large buildings and industrial complexes.
10. Industrial Manufacturing

Used in a variety of manufacturing processes requiring reliable fluid control.
11. Chemical Processing

Critical for handling corrosive and hazardous chemicals requiring high integrity and reliability.
12. Fire Safety System

Due to its fireproof design, it is often integrated into fire extinguishing systems, especially in industrial settings.

These applications highlight the versatility and reliability of trunnion mounted ball valves in a variety of high pressure and critical service environments.

Frequently Asked Questions

What are the specifications of this Trunnion Mounted Ball Valve?

This valve is a 6-inch, 600LB Trunnion Mounted Ball Valve with a Flange End connection and Gear Box operation. The body is made from WCB material, designed to API6D standards, and tested to API598 specifications.

Why is the trunnion design beneficial for high-pressure systems?

The trunnion design fixes the ball at both the top and bottom. This configuration reduces load and friction on the valve seats, lowering the operating torque and ensuring stable, reliable performance in high-pressure applications.

What standards apply to the dimensions and testing of this valve?

The valve follows the API6D design standard. The face-to-face (FTF) dimension conforms to ASME B16.10, the flange dimension is designed to ASME B16.5, and the testing process adheres to the API598 standard.

What is Double Block and Bleed (DBB) capability?

DBB capability allows the trunnion mounted ball valve to isolate both the upstream and downstream sides simultaneously. This allows operators to safely bleed pressure or fluid from the cavity between the seats.

In which industries are these valves commonly used?

They are widely used in demanding sectors such as the oil and gas industry, petrochemical processing, power generation, water and wastewater treatment, marine and offshore applications, LNG/cryogenics, and fire safety systems.
