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 used in a wide range of applications, especially where high pressure, large diameter, and reliable sealing are required. Here are some of the primary applications:
1. **Oil and Gas Industry**:
**Upstream**: Used in drilling operations, production manifolds, and wellhead equipment.
**Midstream**: Ideal for pipeline systems, storage facilities, and compressor stations.
**Downstream**: Commonly found in refineries and petrochemical plants for controlling process flows.
2. **Petrochemical Industry**:
Utilized in the transportation and processing of chemicals, where robust and reliable sealing is critical.
3. **Power Generation**:
Used in power plants, including nuclear, thermal, and hydroelectric, to control steam, water, and other fluids in high-pressure systems.
4. **Water and Wastewater Treatment**:
Employed in large-scale water treatment plants and distribution systems for their 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 essential.
6. **LNG and Cryogenics**:
Used in liquefied natural gas (LNG) plants and cryogenic processes due to their ability to perform well at low temperatures.
7. **Mining and Minerals Processing**:
Applied in slurry handling, ore processing, and other high-abrasion environments.
8. **Pulp and Paper Industry**:
Used in the processing and transport of pulp and paper products, where large volumes and high pressures are common.
9. **HVAC Systems**:
Utilized in heating, ventilation, and air conditioning systems for large buildings and industrial complexes.
10. **Industrial Manufacturing**:
Used in various manufacturing processes where reliable fluid control is necessary.
11. **Chemical Processing**:
Employed in the handling of corrosive and hazardous chemicals where high integrity and reliability are needed.
12. **Fire Safety Systems**:
Often integrated into fire suppression systems, especially in industrial settings, due to their fire-safe design.
These applications highlight the versatility and reliability of trunnion mounted ball valves in various high-pressure and critical service environments.
