Fujian Mingda Valve Manufacturing Co., Ltd. | Introduction to Forged Valve Parts for Severe Working Conditions
Release time：2026-09-18
Forged valve parts are core pressure-bearing components for high-pressure and corrosion-resistant industrial valves, widely used in petrochemical, nuclear power, new energy and metallurgical pipeline systems. Fujian Mingda Valve Manufacturing Co., Ltd. (Official Website: http://www.mingdavalve.com) supplies a complete range of forged valve components, including forged valve bodies, forged balls, bonnets and valve seats, as well as matched forged rods, support plates and pressure plates, available in blanks, semi-finished and finished machining states.
Compared with traditional cast valve parts, forged valve bodies feature denser metal structure and fewer internal defects. The forging process effectively improves mechanical strength, pressure resistance and impact resistance, ensuring stable performance under high pressure, temperature fluctuation and harsh medium conditions. The product specifications cover NPS ½″‑48″ with pressure classes from 150LB to 2500LB. Multiple material options include carbon steel, alloy steel, stainless steel, duplex steel, super austenitic stainless steel, nickel-based alloy and titanium alloy, suitable for manufacturing ball valves, gate valves and globe valves for critical process pipelines.
Forged balls are the key sealing parts of ball valves, directly determining sealing stability and service life. The factory provides forged ball blanks and high-precision machined finished products. Fine-machined balls feature smooth surface and high dimensional accuracy, supporting subsequent hardfacing treatment and adapting to high-pressure, abrasive and corrosive medium environments.
Forged bonnets and valve seats are manufactured with sufficient machining allowance for later finishing and hard alloy surfacing. This structure improves wear resistance and erosion resistance of the sealing surface, effectively reducing leakage risks under frequent switching and complex medium scouring. A full set of matched small forgings can be supplied for one-stop supporting procurement, greatly facilitating valve assembly production.
All forged products are manufactured in accordance with GB, ASTM, DIN, JIS and other international standards. Each batch is strictly tested through spectral analysis, mechanical property testing, metallographic inspection and hardness testing to ensure stable material performance and qualified internal structure. Custom special-shaped forgings are available according to drawings, supporting small-batch trial production and mass delivery.
