    H41H flange forged steel check valve has three bonnet design forms. The first is a bolted bonnet. The valve designed according to this design form has a bolt and nut connection between the valve body and the bonnet, and spiral wound gasket (316 It is made of flexible graphite) for sealing. If customers have special requirements, they can also be connected by metal rings. The second design form is a welded bonnet. According to this design form of valve, the valve body and bonnet are connected by threads, all welded Sealing. If customers have special requirements, they can also use penetration welding connection. The third type is pressure self-tightening bonnet. The valve designed according to this design form has a threaded connection between the valve body and the bonnet, and the internal pressure self-tight ring seal .

    Forged steel valves are mainly used in the pipelines of various systems in thermal power plants to cut off or connect pipeline media. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, forged steel valves are characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Due to the special performance, technical characteristics and working conditions, the product has also become a substitute for other products.

    The products adopt ISO, API, ANSI, BS, DIN, NF, JIS, JPI, GB, JB and other advanced domestic and foreign standards. The product diameter is 3/8"-2" (DN10mm-50mm), and the pressure rating is 150Lb- 2500Lb (0.1Mpa-42.0Mpa), working temperature is -196℃-680℃.
