Forged Steel Globe Valve, Straight-through globe valve

Product Overview

This forged steel flange globe valve is a special small-bore high-pressure industrial stop valve, designed and manufactured in full compliance with major global industrial valve standards including ISO, EN, DIN, ASME and GOST. With a fixed full size range from DN15 to DN50 (NPS 1/2″ to NPS 2″), it adopts an integral forging process for the valve body, with dual core functions of high-pressure pipeline on-off shut-off and precise flow regulation, exclusively developed for small-bore high-pressure and high-temperature working conditions.

With international standard flanged connection, the forged steel valve body has the core advantages of high density, high strength, impact resistance, and no sand holes or blowholes. It has stronger pressure bearing capacity, better high temperature resistance and longer sealing life than conventional cast steel valves. It is widely used in power stations, petrochemical, fine chemical, oil and gas fields, instrument pipelines and other small-bore high-pressure working conditions, and is a core model of small bore forged steel globe valve for global foreign trade procurement and industrial project small-diameter pipeline supporting.

Core Product Features

1. Integral Forged Body, High Strength for High Pressure & Temperature

   The valve body is integrally forged with international standard forged steel materials, with fine and uniform metal grains, no casting defects such as sand holes, blowholes or shrinkage porosity. Compared with cast steel valves of the same specification, it has higher density, stronger pressure bearing capacity, and better impact and fatigue resistance. It can stably adapt to harsh working conditions of high temperature, high pressure and frequent opening and closing, with far better structural stability than cast valves.

2. Precision Sealing Structure, Zero Leakage & High Reliability

   The valve plug and seat adopt paired precision grinding process for high fit, with flexible graphite multi-layer packing sealing structure. Its sealing performance meets ANSI B16.104 Class VI and EN 12266 zero leakage standards, completely eliminating internal and external medium leakage. The small-bore valve stem has a short opening and closing stroke, with smooth switching without jamming, suitable for long-term stable operation of high-pressure media, and fully complying with global environmental and safety regulations.

3. Full Global Standard Compatibility, Strong Flanged Connection Adaptability

   Adopting international standard flanged connection, it is fully compatible with major global flange standards including EN, DIN, ASME and GOST. The full size range from DN15 to DN50 has accurate and unified dimensions, which can be directly connected to the existing small-bore pipeline systems of customers around the world without additional modification. It is easy to install and disassemble, perfectly adapting to the small-diameter pipeline supporting needs of different countries and standards.

4. Optimized Streamlined Flow Channel, Low Resistance & Precise Regulation

   The large curvature streamlined flow channel is optimized for the characteristics of small-bore pipelines, with no flow dead angle and no medium retention, low fluid resistance and low pressure loss, effectively avoiding turbulence and water hammer impact. The valve stem has good lifting linearity, which can realize stepless precise regulation of fluid flow and pressure in small-bore pipelines, with stable opening and closing without vibration and noise.

6. Full-Process Strict Quality Control, Long Service Life & Low Maintenance

   Forgings of each valve are subject to non-destructive testing (NDT), and all finished products pass strict hydraulic strength test and pneumatic sealing test before delivery, with stable and reliable performance in line with international general quality inspection standards. The overall structure is compact with no quick-wear parts, no complicated daily maintenance is required, which greatly reduces the full life cycle operation and maintenance cost of the valve.
