Product Introduction

Shanghai HongbaQ941H-16 DN125 Cast Steel Electric High Temperature Ball Valve for Steam PipelineThis new product integrates the advantages of various valve structures, including ball valves, V-valves, and track ball valves. The ball valve features a double eccentric sealing structure, offering minimal wear, low torque, excellent sealing performance, and a long service life. The valve seat and hemispherical body are treated with a special hardening process, particularly suitable for demanding operating conditions and requirements for resistance to erosion.

Product Features

1. Due to the hard-sealed electric ball valve's valve core being spray-welded with alloy steel and the sealing ring being surfacing-welded with alloy steel, the hard-sealed electric ball valve does not produce excessive wear during operation. (Its hardness coefficient is 65-70).

2. Excellent sealing performance; the hard-sealed electric ball valve's sealing is achieved through manual polishing until the valve core perfectly fits the sealing ring. Thus, its sealing reliability is guaranteed.

3. The switch is light due to the spring at the bottom of the sealing ring in the hard-sealed electric ball valve, which tightly grips the valve core. Thus, the switch is very light when the external force exceeds the spring's pre-tension.

4. Long lifespan; applied in sectors such as oil, chemicals, power generation, papermaking, atomic energy, aviation, and daily life.

【Selection Principles】

1. For the main pipeline of oil and other substances, which requires pipeline cleaning and underground installation, use full-bore, fully-welded ball valves; for above-ground installation, choose full-bore welding or flange-connected ball valves; for branch pipes, use flanged or welded connections with full-bore or reduced-bore ball valves.

2. Pipeline and storage equipment for finished oil use ball valves connected by flanges.

3. Floating ball valves with flange and internal threaded connections are used on city gas and natural gas pipelines.

4. In the oxygen pipeline system of the metallurgical system, it is advisable to use a fixed ball valve with a flange connection that has been strictly degreased.

5. For pipeline systems and equipment handling low-temperature media, it is advisable to use low-temperature ball valves with valve covers.

6. On the pipeline system of the catalytic cracking unit in the refining facility, a lift-pipe type ball valve can be selected.

7. In the equipment and pipeline systems of chemical systems containing corrosive media such as acids and alkalis, it is advisable to use all-stainless steel ball valves with valve seat seals made of austenitic stainless steel.

8. For pipeline systems or equipment on high-temperature media in metallurgical systems, power systems, petrochemical plants, or urban heating systems, the ball valve can be selected.

9. For flow regulation, you can choose a regulating ball valve with a V-shaped opening, powered by worm and worm gear, pneumatic, or electric.
