The TRLAN C95800 Aluminum Bronze Trunnion Ball Valve is a high-performance flow control solution, engineered for critical marine, offshore and industrial scenarios demanding stable reliability and strong corrosion resistance, used for seawater.

The ball valve with drain port adopts a rugged ASTM B148 C95800 aluminum bronze body, matched with precision Monel 400 (ASTM B564 N04400) ball and stem, ensuring steady performance and extended service life in severe corrosive fluid environments.

More Material Advantages

Valve Body: C95800 Aluminum Bronze

Cast from marine-grade ASTM B148 C95800 alloy, the trunnion valve excels in resisting seawater, brine and chemical corrosion. The 18×16 inch reduced bore design maintains solid structural strength and stable fluid delivery.

Internal Ball & Stem: ASTM B564 N04400 (Monel 400)

The ball and trunnion stem are precision-machined from nickel-copper alloy:

Outstanding corrosion resistance for seawater and aggressive chemical media;

Optimized friction fit with RPTFE seats, reducing operating torque and improving durability.

Key Functional Features

Worm Gear Actuator: Ductile iron gear unit for labor-saving operation, adaptable to frequent switching and heavy-duty service.

Flanged Connection: ASME B16.5 FF flat face flange for firm installation, vibration resistance and tight sealing.

Drain / Vent / Injection Port: Integrated ports support on-site upkeep, cavity pressure relief and emergency sealant injection.

Fire Safe & DIB-1: Compliant with API 607 fire safe and DIB-1 bidirectional sealing, satisfying high-safety working needs.

Standard Compliance: Manufactured per API 6D, ASME B16.10 / B16.34 and API 598; marked and inspected to MSS SP-25, fully meeting industrial and offshore project specifications.

Internal Ball: ASTM B564-N04400 (Monel 400)

 

Superior Corrosion Resistance: Effectively resists pitting, crevice and stress corrosion in seawater, acids, alkalis and organic solvents, well suited for offshore and chemical working conditions.

High Mechanical Strength: Keeps steady mechanical properties at standard working temperatures, delivering dependable sealing and flow control under rated pressure.

Wear Resistance: Precision smooth surface lowers friction with seat parts, easing abrasion, prolonging service life and cutting daily maintenance needs.

(18×16 Size, Class 150 Pressure Rating

 

This valve body adopts C95800 aluminum bronze, featuring strong resistance to pitting and crevice corrosion. It endures long-term erosion by seawater and harsh chemical media, suitable for marine and offshore harsh conditions. With 18×16 inch reduced bore and Class 150 pressure rating, it runs steadily in pressurized fluid systems. Smooth inner passages lower pressure loss and boost conveying efficiency.

Flanged C95800 Aluminum Bronze Ball Valve

 

This valve uses flanged connection per ASME B16.5 FF standard, achieving firm pipeline connection via bolt fastening. Tightly fitted sealing surfaces withstand impact and vibration under Class 150 working conditions and prevent leakage. Highly standardized flange design needs no special tools for on-site installation, greatly shortening construction time. It fits various industrial pipelines, ideal for scenarios requiring reliable sealing and fast installation.

C95800 Aluminum Bronze Trunnion Ball Valve with Worm Gear Actuator

 

The core of this gear operated ball valve is its worm gear actuator, which features a gear reduction structure that significantly reduces the operating torque. It only requires a small external force to drive the large-diameter valve to open and close, making operation much more labor-saving. Equipped with a visual position indicator, it can intuitively feedback the valve's on-off status to avoid misoperation, which is especially suitable for frequent adjustment or remote control needs in industrial scenarios, enhancing the safety and controllability of the system.
