Product Overview
TRLAN NPS14 Class900 RF full-bore trunnion ball valve is engineered to API 6D, ASME B16.5/B16.10/B16.34, NACE MR0175 and API 607 fire-safe standards. Its body and adaptor use ASTM A105N carbon steel; ball, stem and seat parts are ASTM A182 F51 and Inconel X-750 seat springs.
Fitted with graphite fire-safe seal, anti-static assembly and graphite-Inconel wire packing, the A105N Ball Valve ASME16.34 Standard suits crude oil, diesel, boiler feedwater and high-temperature thermal oil. All valves pass strict tests: 23.0MPa shell hydro test, 16.9MPa closure hydro test and 0.6MPa air tightness test. Full-bore RF flange design minimizes flow resistance for high-pressure petrochemical and power plant piping systems.
Details of the Valves
Class 900LB Forged A105N Carbon Steel Body with Exceptional Strength & Toughness
This forged A105N carbon steel features a forged A105N carbon steel body rated for 900LB working pressure, offering excellent strength and toughness. The hot-forging process refines the internal grain structure, eliminating common casting defects like porosity and segregation, which ensures consistent mechanical performance under extreme pressure fluctuations. The robust forged body effectively resists impact loads and prevents brittle fracture


High-strength Evenly Distributed Bolts Deliver Balanced Clamping & Stable High-pressure Sealing
High-strength bolts evenly distributed around the best quality ball valves body provide perfectly balanced clamping force, ensuring reliable sealing performance even under Class 900 high-pressure working conditions. Symmetric bolt layout eliminates localized stress concentration, compressing the sealing gasket uniformly across the split joint surface. This design prevents gasket deformation or blowout under extreme pressure fluctuations, while also simplifying maintenance disassembly. Ideal for high-pressure oil, gas and petrochemical pipelines, it guarantees zero-leakage operation for long-term safety and stability.
Double Stage Gearbox with Reducer for Dust & Moisture Resistance in Harsh Outdoor Conditions
This api 6d ball valve manufacturers is fitted with a double reducer gearbox designed to effectively resist dust and moisture intrusion. The fully enclosed cast housing with precision-machined mating surfaces prevents contaminants from reaching internal gears, ensuring reliable operation in harsh outdoor industrial environments such as petrochemical plants and oil fields. The robust design withstands fluctuating weather conditions and corrosive atmospheres, minimizing maintenance frequency and extending the service life of the gear mechanism in long-term field service.


Vent Valve Design for Air Purging During Pressurization, Ensuring Reliable Valve Operation
Equipped with a built-in vent valve design, this oil ball valve effectively purges trapped air during system pressurization. By releasing residual gas from the valve cavity, it eliminates air pockets that could cause cavitation, unstable flow, or improper valve function under high pressure. This simple yet functional feature ensures smooth medium flow and consistent valve performance from commissioning through long-term operation, making it an ideal choice for high-pressure oil, gas, and petrochemical process piping systems.
