Carbon Steel 6inch 6000LB Trunnion Mounted Ball Valve - China Factory Suppliers for High-Performance Valves

Products Specification

Features

• 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.

Application

• 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. 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.
