Description
Manual Forged Steel Welded Globe Valve
The Manual Forged Steel Welded Globe Valve is a high-precision, heavy-duty industrial flow control valve engineered for strict on-off and throttling control of high-temperature, high-pressure fluid media. Adopting integral forging process and welded end connection design, this manual globe valve features compact structure, high structural strength, zero leakage performance and long service life. Different from cast steel valves, the forged steel body eliminates trachoma, porosity and crack defects, ensuring stable operation in harsh industrial working conditions.
Equipped with a manual handwheel operating mechanism, the valve realizes flexible and accurate flow regulation and pipeline cut-off. It is widely applicable for steam, oil, gas, water and corrosive medium pipelines in petrochemical, power plant, metallurgy, energy and other industrial fields, fully complying with international industrial pressure vessel and pipeline valve standards.

Advantages
Final Solution
Integral Forged Steel Body, Ultra-High Durability
Made of premium forged carbon steel, stainless steel and alloy steel (A105, F304, F316, F11, F22 optional), the one-piece forged structure boasts uniform material density, strong pressure resistance and impact resistance. It effectively avoids structural damage caused by high pressure and temperature fluctuation, far superior to traditional cast valves in safety and stability.
Reliable Welded Connection, Zero Leakage
Designed with socket weld or butt weld end connections, the valve can form an integrated seamless connection with pipelines after full penetration welding. It solves the leakage risk of threaded and flange connections under ultra-high pressure, realizing permanent tight sealing and adapting to long-term stable operation of high-pressure pipelines.
Precise Manual Throttling & Cut-off Performance
Adopting conical plug-type sealing disc design with precision machining sealing surface, the valve features small opening and closing resistance and accurate flow regulation. The manual handwheel realizes stepless adjustment of fluid flow, with excellent sealing tightness and no medium leakage in fully closed state.
Features
• Valve Body: Integral forging forming, no welding seam on the main body, high structural rigidity, pressure-resistant and anti-deformation; streamlined flow channel design reduces fluid resistance and medium erosion, improving pipeline transmission efficiency.
• Valve Trim: Forged steel integral stem with integral backstop shoulder, matching with bonnet backseat to realize reliable limit and sealing; valve disc adopts movable rotating structure, ensuring automatic alignment with sealing seat and uniform sealing compression.
• Sealing System: Hard seal (Stellite alloy surfacing) and soft seal optional; hard seal surface is wear-resistant and high-temperature resistant, suitable for high-pressure steam and abrasive media; spiral wound graphite gasket or metal ring gasket for bonnet sealing, realizing zero leakage.

FAQ
FAQ
Q: What is a forged steel welded globe valve used for?
A: This manual forged steel globe valve is designed for precise on-off and throttling control of high-temperature, high-pressure fluids. It is widely used in steam, water, oil, and gas pipeline systems for thermal power, petrochemical, metallurgy, and municipal infrastructure projects, delivering stable and safe flow regulation under harsh working conditions.
Q: What are the advantages of forged steel body compared with cast steel valves?
A: Forged steel body features uniform material density, higher structural strength, and no internal porosity or trachoma defects. It offers better pressure resistance, temperature resistance, and impact toughness. Compared with cast valves, it avoids body deformation, leakage, and cracking risks under extreme high-pressure and high-temperature environments, ensuring longer service life and higher operational safety.
Q: What weld end types do you support?
A: We provide two mainstream welded connection types: Butt Weld (BW) and Socket Weld (SW). Fully welded integration with pipelines eliminates potential leakage points of flange and thread connections, which is ideal for long-term stable operation of high-pressure sealed pipelines.
Q: What pressure classes and sizes are available?
A: Standard specifications cover NPS 1/2"–2" (DN15–DN50) and pressure classes including Class 150, 300, 600, 800, 1500, and 2500. Custom size and pressure grade support are available for special project requirements.
Q: Is the valve zero-leakage?
A: Yes. Adopting precision-machined conical sealing and optional Stellite alloy hard surfacing, matched with high-performance graphite or metal sealing gaskets, the valve achieves excellent tightness. Every product undergoes 100% hydraulic and air tightness testing to ensure zero leakage in fully closed status.
