12" 300LB A105N Forged Globe Valve

A105N Forged Steel Body: The valve body is produced from ASTM A105N forged steel with dense grain structure, outstanding mechanical property and superior pressure bearing capacity to adapt to high-pressure working conditions.

Integrally Forged Large Bore Body: The 12-inch DN300 large-size body adopts integral forging craft to remove potential casting defects and guarantee uniform wall thickness and integral structural stability.

Straight-Through Flow Path Design: Fluid flows linearly along the central line of valve seat with low flow resistance and small pressure drop, fit for working conditions needing accurate flow adjustment.

Rising Disc Structure: The disc lifts vertically along the central axis of valve stem, causing slight abrasion on sealing surfaces and tight shutoff, achieving linear flow adjustment performance.

Flanged Connection: Equipped with RF raised face flange connection conforming to ASME B16.5 standard, ensuring stable installation and good tightness for large-caliber pipeline systems.

Pressure-Seal Bonnet: Pressure-seal bonnet is adopted for Class300 high pressure service. Higher medium pressure brings better sealing effect to effectively avoid external medium leakage.

Stellite Hard Alloy Overlay Sealing Surface: Both seat and disc sealing surfaces are hardfaced with Stellite alloy, featuring great wear and corrosion resistance to prolong valve service life.

Backseat Structure: When the valve is fully opened, the disc forms metal sealing with bonnet backseat, allowing on-site packing replacement and preventing medium leakage outward.

Anti-Blowout Stem Design: The bottom of valve stem is fixed by T-type head or pin structure to prevent stem blowout under internal medium pressure and guarantee safe operation.

Handwheel & Bevel Gear Operation: Standard bevel gear device is matched for 12-inch large bore to lower operating torque for easy opening and closing; electric actuator is optional to realize remote automatic control.

Oil & Gas Industry: Used for fluid cut-off and flow regulation on long-distance transportation pipelines, oil and gas gathering pipelines, compressor stations and metering stations.

Petrochemical Industry: Control high temperature and high pressure medium inside refinery equipment, cracking units and catalytic reforming devices.

Power Generation Industry: Serve for shut-off and flow adjustment on main steam pipeline, feedwater pipeline and bypass pipeline of thermal power plants.

Chemical Industry: Medium control for high-pressure production units including synthetic ammonia and methanol processing facilities.

Metallurgical Industry: Safe isolation for high-temperature high-pressure pipelines carrying blast furnace gas and industrial oxygen.

District Heating Industry: Main pipeline flow regulation and emergency shutoff for centralized heating network.

Excellent High Pressure Large Bore Safety Performance: Integral forging and A105N raw material greatly improve overall structural stability of 12-inch valve under Class300 pressure, ruling out equipment failure risk caused by casting defects.

Accurate Flow Modulation Capacity: Straight flow channel and rising disc design deliver stable adjusting property, ideal for process pipelines requiring precise flow control.

Long Service Life of Sealing Parts: Stellite hard surfacing effectively resists medium erosion and corrosion, lengthening maintenance cycle and cutting overall operating cost.

Multi-layer Safety Protection: Pressure-seal bonnet, backseat and anti-blowout stem jointly protect equipment and operators during high-pressure running.

Easy Field Maintenance: Flanged connection and replaceable seat design shorten overhaul duration and reduce production shutdown loss.

Universal Standardization: Full compliance with global ASME and API standards enables seamless matching with existing pipeline, saving engineering design and purchasing expense.
