Small Size Forged Valve
Small Size Forged Valve refer to valves with a nominal diameter less than or equal to DN50 and manufactured using a forging process. The valve body is usually made of carbon steel, alloy steel or stainless steel, and has the advantages of compact structure, high strength and good sealing performance.
Characteristics of Small Size Forged Valve

Advantages
Compact structure and light weight: Due to the forging process, the valve body structure is more compact, lighter, and easier to install and maintain.
High strength and good pressure resistance: Forged steel material has higher strength and toughness and can withstand higher pressure and impact.
High temperature resistance and corrosion resistance: According to different media and working conditions, different materials and surface treatment processes can be selected to improve the high temperature resistance and corrosion resistance of the valve.
Long service life: Forged steel valves have higher mechanical properties and longer service life.

Applicable environment of Small Size Forged Valve
- High-pressure, high-temperature, corrosive medium pipelines: For example, petrochemical plants, thermal power plants, nuclear power plants, etc.
- Occasions with high requirements for valve strength and sealing performance: For example, natural gas pipelines, liquefied petroleum gas pipelines, etc.
- Occasions with limited space: For example, ships, aircraft, etc.

Selection of Small Size Forged Valve
When selecting Small Size Forged Valve, the following factors need to be considered:
- Media type: Different media require valves of different materials.
- Pressure level: The working pressure of the valve needs to be greater than or equal to the pressure of the pipeline system.
- Temperature range: The working temperature of the valve needs to adapt to the temperature of the medium.
- Connection method: Select the appropriate valve connection method according to the connection method of the pipeline system.
- Flow requirement: Select the appropriate valve diameter according to the flow requirement.
- Drive mode: Select manual, pneumatic, electric or hydraulic drive mode according to actual needs.
Small Size Forged Valve play an important role in high-pressure, high-temperature, and corrosive medium pipelines due to their compact structure, high strength, and good sealing performance.
