What is the difference between CE-certified and API-certified 3PC trunnion ball valves in high-temperature service? This article compares certification logic, materials, sealing design, manufacturing standards, and real-world application to help you choose a more stable solution.

Why do more offshore engineering projects specify API 6D certification for forged trunnion ball valves? This easy-to-read guide compares API 6D and API 600 and explains which standard better fits offshore platform service.

Double Block and Bleed (DBB) flanged trunnion mounted ball valves are widely used in industrial fluid systems, including oil and gas, chemical processing, and power generation. These valves provide superior safety, isolation, and maintenance flexibility, allowing both upstream and downstream shutoff with a bleed function in between. A critical factor in their performance, reliability, and longevity is the selection of materials for valve body, ball, seat, and sealing components.

In oil pipeline engineering, frequent high-pressure leakage means the system needs serious optimization.
For a 1500LB A105N large diameter trunnion ball valve, API6D certification is usually more suitable than a general ISO certification when the application is pipeline-critical, especially in crude oil, natural gas, and high-pressure transmission systems.

Double Block and Bleed (DBB) flanged trunnion mounted ball valves​ are widely used in critical fluid systems, including oil & gas, chemical processing, and power generation. These valves are designed for high-pressure applications where leakage prevention and operational reliability are paramount. One of the most critical aspects of DBB valve performance is the choice of gasket materials for the bonnet and body, which directly affects sealing efficiency, durability, and safety.

Double Block and Bleed (DBB) ball valves are critical components in high-pressure and hazardous fluid systems, offering enhanced safety, operational efficiency, and maintenance flexibility. Among their key performance differentiators are the types of ball valve seats—floating and trunnion-mounted—which significantly impact reliability, sealing performance, and operational torque.

In hydraulic oil transfer systems, the structure of an ISO-certified A105 hydraulic ball valve directly affects sealing performance, pressure stability, and maintenance cost. This article explains the risks of choosing the wrong valve structure, including leakage, blockage, pressure drop, and downtime.

Why are ISO-certified trunnion ball valves often preferred in power and energy engineering for high-cycle on/off service? This article explains sealing stability, torque control, wear resistance, and long-term reliability to help you choose the right valve.

Double Block and Bleed (DBB) ball valves are critical components in high-pressure and high-temperature piping systems. One of the most important design considerations for DBB valves is the seat material, which directly affects sealing performance, longevity, and compatibility with various media. Cho

C95800 floating ball valves are widely used in offshore, marine, and coastal piping systems because of their strong resistance to seawater corrosion. This article explains the material advantages, corrosion mechanisms, and key differences from standard stainless steel ball valves.
