As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance API 6D Trunnion Mounted Ball Valve with IP67 Waterproof Electric Actuator and Fire-Safe Design. Engineered for the most demanding industrial applications, this valve combines robust construction, reliable automation, and critical safety features to ensure uninterrupted flow control in pipelines worldwide. Since our establishment in 2016, we have dedicated ourselves to producing valves that meet the stringent requirements of global markets, including North America, South America, Europe, Asia, Africa, and Oceania, with an annual export value demonstrating our commitment to quality and customer trust.

This valve is specifically designed for high-pressure, large-diameter, and critical service applications where leakage is not an option. The trunnion-mounted design provides superior stability and reduces operating torque, while the integrated electric actuator offers precise and remote operation. Its fire-safe certification ensures operational integrity even under extreme emergency conditions, protecting personnel, assets, and the environment.

Core Product Features & Technical Advantages:

API 6D Compliant Design: Manufactured in strict accordance with API 6D specifications for pipeline valves, ensuring dimensional interchangeability, material integrity, and performance reliability for oil, gas, and petrochemical services.
Trunnion-Mounted Ball Construction: Features a ball supported by trunnion bearings at the top and bottom. This design minimizes seat load and wear, significantly reduces operating torque, and prevents excessive stress on the valve seats, leading to a longer service life, especially in high-pressure applications.
IP67 Waterproof Electric Actuator: The integrated actuator is rated IP67, making it completely dust-tight and protected against temporary immersion in water. This ensures reliable operation in harsh outdoor environments, rain, or washdown areas without the need for additional protective enclosures.
Certified Fire-Safe Design: Engineered to API 607/API 6FA or similar standards. In the event of a fire, the primary soft seals are designed to burn away, after which secondary metal-to-metal seals engage to maintain a bubble-tight shut-off, preventing catastrophic fluid release.
Robust Material Selection: Available in a variety of body materials (e.g., A216 WCB, A351 CF8/CF8M) and seat/seat materials (PTFE, RPTFE, metal) to suit specific media, temperature, and pressure conditions, from cryogenic to high-temperature services.
Low Maintenance & Easy Operation: The trunnion design and quality construction minimize wear on sealing components. The electric actuator provides smooth, reliable operation with options for fail-safe (spring return) and modulating control, integrating seamlessly with plant DCS or SCADA systems.

Benefits for Your Operation:

Enhanced Safety & Compliance: The fire-safe design is critical for meeting safety regulations in hydrocarbon processing, refining, and transmission, reducing liability and risk.
Superior Reliability in Harsh Conditions: The IP67 actuator and robust valve construction ensure dependable performance in remote, offshore, or environmentally challenging locations, minimizing downtime.
Reduced Total Cost of Ownership: Lower operating torque extends actuator life, while the durable trunnion design reduces maintenance frequency and replacement part costs over the valve's lifespan.
Operational Efficiency: Electric actuation allows for fast, precise remote control and automation, improving process efficiency and enabling integration into modern industrial control systems.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of a trunnion-mounted ball valve over a floating ball valve?
A: The trunnion-mounted design is superior for larger sizes and higher pressure classes. It uses mechanical anchors (trunnions) to hold the ball in place, drastically reducing the operating torque and seat wear compared to floating ball designs, where the ball is pushed against the seat by line pressure.
Q: Can this valve be used for both on/off and throttling (modulating) service?
A: Yes. While primarily designed for reliable on/off service, when paired with a modulating electric actuator and appropriate trim, it can be used for flow control applications. Please specify your control requirements when inquiring.
Q: What does the IP67 rating on the actuator mean for my application?
A: IP67 means the actuator enclosure is completely protected against dust ingress (6) and can withstand temporary immersion in water up to 1 meter for 30 minutes (7). This makes it ideal for outdoor installations, areas with high humidity, or washdown zones without needing an extra protective box.
Q: How is the fire-safe functionality tested and certified?
A: Fire-safe valves undergo rigorous testing per standards like API 607, where the valve is subjected to a specified furnace fire for 30 minutes while under pressure, followed by a cooling period. It must maintain internal and external leakage within strict limits to be certified.
Q: Are different material combinations available for corrosive services?
A> Absolutely. We offer various body materials like carbon steel, stainless steel (304/316), and alloy steels, along with seat materials including PTFE, reinforced PTFE, and metal (Inconel, Stellite). The combination can be selected based on your specific media, temperature, and pressure.
Q: What is the typical lead time for an order of these valves?
A: Lead time depends on the size, pressure class, material, and actuator specifications. Standard configurations may have shorter lead times, while custom-engineered solutions require more time. We provide accurate lead time estimates upon receipt of your detailed inquiry.
Q: Do you provide actuated valves as a complete package, or do I source the actuator separately?
A: We supply the valve and actuator as a fully assembled, tested, and ready-to-install package. This ensures perfect compatibility, simplifies procurement, and provides a single point of responsibility for warranty and support.
Q: What after-sales support do you offer?
A: We provide comprehensive technical documentation, including test reports, material certificates, and installation manuals. Support for installation guidance and spare parts is available to ensure optimal long-term performance of your valve.
