Forged National Standard Globe Valve

Many engineering professionals who purchase pipe valves often worry about encountering problems. They either encounter products with incorrect dimensions that cannot be installed, or the valves break down shortly after use. Especially in high-pressure and high-temperature conditions, any issues can be extremely troublesome. Our forged National standard globe valve is specifically designed for such demanding conditions.

Core advantages

The valve body is made of A105N forged carbon steel, which is different from ordinary cast valve bodies. The forging process eliminates invisible defects such as pores and sand holes in the steel, making the structure more dense and providing a direct increase in pressure-bearing capacity. This forged National standard globe valve can withstand a maximum temperature of 425°C and is within the range of PN16 pressure. Even fluctuations in pressure within steam pipelines can be reliably handled. The sealing surface uses Samtler cobalt-based hard alloy welding, which is wear-resistant and resistant to scratches. It can withstand tens of thousands of openings and closings without leakage. The valve stem has undergone quenching and nitriding treatment, making it corrosion-resistant. Even with slightly corrosive media, it is not afraid. Moreover, the packing can be replaced online without having to stop and dismantle the entire valve, making maintenance much easier.

Technical specifications

This is the J41H-16C DN25 PN16 that people often ask about. The nominal diameter is 25mm, the nominal pressure is 1.6MPa, the valve body material is A105N, the connection method is standard flange connection, and the design and manufacture fully comply with the GB12235 national standard. The structural length and flange standards all conform to HG/T20592. The test and inspection have also passed the JB/T9092 standard. Every dimension is precisely controlled, and once received, it can be directly connected to the pipeline without any modifications. Moreover, our forged National standard globe valve can be changed to different materials according to your working conditions. Stainless steel and alloy steel can be used. It can meet the requirements of different media.

Competitive advantages

Compared with competitors, many small factories use cast valve bodies to save costs. They may look similar, but there are sand holes inside, and they leak after using for one or two years. In high-pressure conditions, they are prone to safety accidents. Our forging process, although more costly, has a valve body strength that is 1.5 times higher than that of casting. The lifespan can be doubled. Our forged National standard globe valve can withstand erosion in particles-containing media and will not easily break. In the long run, it is more cost-effective and does not require frequent valve replacements, which saves production time.
