Forged globe valve is a critical pipeline component for flow isolation and throttling under high temperature & high pressure working conditions in oil & gas, thermal power, petrochemical and coal chemical industries. Compared with cast globe valves, one-piece forged body features higher density, excellent creep resistance and stable mechanical performance, among which ASTM A105N normalized carbon steel Class300LB forged globe valve becomes the most popular valve type for global medium & high pressure industrial piping systems. With over 10+ years’ experience in forged valve production, J-VALVES develops and manufactures API-standard forged globe valves, the 12” 300LB A105N flanged globe valve (RF/RTJ face) is our flagship industrial valve product with abundant global engineering references.
ASTM A105N material is normalized carbon steel after 900℃ air cooling heat treatment to refine internal grain structure, eliminate forging stress and improve toughness & impact resistance, suitable for working medium like steam, crude oil, natural gas within temperature range -29℃~425℃. Class300LB pressure rating bears up to 5.0MPa nominal working pressure, two flange options: RF Raised Face and RTJ Ring Joint for different tightness requirements of industrial pipeline.
1. Integral Forged Body: Whole steel billet die forging without casting defects like blowhole or sand hole, thickened body design improves tensile strength above 485MPa to avoid body crack under extreme pressure difference;
2. OS&Y Outside Screw & Yoke Structure: Visible rising stem for clear open/close status check, multi-layer packing gland complies with ISO15848 & TA-Luft low fugitive emission regulation for strict environmental leakage control;
3. Flexible Seat Customization: Stellite hardfaced metal seat for high temp abrasive medium, soft seated option for clean water & gas service, J-VALVES provides tailor-made sealing solution per customer’s working condition.
J-VALVES owns full production line from raw steel inspection, precision forging to normalized heat treatment. All A105N raw steel ingots pass spectrum chemical analysis before production, we never use non-normalized A105 substitute material to cut cost, each valve is attached with full material test report for traceability.
Standard forged globe valve ranges from 1/2"~12", Class150~Class2500LB with NPT threaded, SW socket weld, RF/RTJ flanged ends. We also produce alloy steel globe valve in F304/F316/F91 for cryogenic LNG, high temp hydrogenation & corrosive chemical service following ANSI & API602 standardsJ-VALVES.
Every finished globe valve undergoes hydrostatic body strength test, seat tightness air test and stem fugitive emission test before delivery. Products are certified with CE, ISO & API certificates to support third-party inspection from global end users.
J-VALVES builds stocking warehouses and authorized distributors across Southeast Asia, Middle East and North America for fast local delivery, OEM & ODM service available for international bulk engineering procurementJ-VALVES.
All our forged globe valves enjoy 18-month quality warranty. For large power plant & petrochemical project, J-VALVES sends field engineers for installation guidance and long-term spare parts supply.
Kuwait National Oil Company’s crude oil production station carries high temp crude & associated gas at 310℃ under Class300LB working pressure. J-VALVES supplied Stellite hard-seated RTJ flanged A105N globe valves, all passed SGS third-party inspection. The valves have run continuously for 4 years without any leakage, and KNOC places repeated order for phase-II expansion project.
This 600MW coal-fired power plant requires 276pcs 6"/8" Class300LB RF A105N forged globe valve for high pressure boiler feed water (385℃,4.8MPa). With pressure-sealed bonnet design to resist frequent startup pressure fluctuation, our valves work trouble-free for 3 years after commissioning and help customer reduce 32% procurement cost vs imported original brand.
An Indonesian integrated refinery orders 89pcs customized extended-stem A105N RTJ globe valve for hydrogenation reactor outlet pipeline. J-VALVES optimizes stem length based on site layout, pre-assembly & pre-test finished in factory for one-time successful field installation, now we become their long-term qualified valve supplier.
Our forged globe valves are widely used in onshore/offshore oilfield, refinery hydrocracking unit, thermal power plant boiler system, coal-to-chemical synthetic ammonia pipeline, fine chemical high-temperature process line, small LNG storage terminal & metallurgical cooling water system.
