Forged Steel Gate Valve Selection Considerations

  • Media Properties: Choose materials (e.g., F316L + NACE for H₂S resistance) based on corrosion, temperature, and pressure.
  • Pressure-Temperature Rating: Match pipeline design parameters (refer to ASME B16.34).
  • Connection Method: Use threaded/socket weld for space-constrained areas; butt weld for high-pressure applications.
  • Compliance: API certification for oil & gas; ASME BPVC certification for nuclear applications.

How to choose high-quality forged steel gate valve?

Forged steel gate valves Core Advantages

  • High Strength: Forged valve bodies are impact-resistant, with pressure ratings up to Class 2500, ideal for high-pressure environments.
  • Superior Sealing: Metal hard seals (with optional hard alloy surfacing) achieve zero leakage standards, suitable for flammable, explosive, or toxic media.
  • Corrosion Resistance: Made from stainless steel or duplex steel, they withstand acids, alkalis, and seawater corrosion.
  • Longevity: Compact structure and smooth operation ensure a service life of over 10 years.

Forged steel gate valves Application Scenarios

  • Oil & Gas Industry: High-pressure wellheads and gas pipeline block valves, compliant with API 6A/6D standards, resistant to H₂S-containing media.
  • Chemical/Petrochemical: High-temperature and highly corrosive pipelines (e.g., reactor inlets/outlets), following ASME standards.
  • Power Industry: Main steam pipelines in thermal power plants (>540°C/25MPa) and nuclear power cooling circuits, certified under ASME BPVC.
  • Metallurgy/Special Applications: High-pressure oxygen and hydrogen pipelines, requiring impact resistance and anti-static design.

Forged steel gate valves Key Types

  • Connection Types: Threaded (small diameters), flanged (medium/high pressure), welded (high-pressure leak-proof).
  • Wedge Types: Parallel (low-pressure clean media), wedge-style (high-pressure/high-temperature media).

Forged steel gate valves Maintenance Tips

  • Regularly inspect seal wear and stem leakage.
  • Tighten bolts in high-temperature conditions and apply anti-corrosion coatings for outdoor use.

Sealing Element

The sealing element is vital for valves, preventing media leakage when closed. Made of durable, corrosion-resistant materials, it withstands pressure, temperature, and corrosion. Its repeated friction during operation makes material choice and manufacturing quality crucial for sealing performance and valve lifespan, regardless of valve type.

Valve Stem

The valve stem links the closure element to the operating mechanism, controlling its movement to regulate media flow. It requires strength and rigidity to withstand forces while maintaining stability. Its design and quality directly impact the valve’s flexibility and durability.

Valve Body

The valve body serves as the core structure of the valve, forming the main framework that provides installation and support for other components. It houses the internal channels for media flow. Whether it’s a ball valve, butterfly valve, or gate valve, the valve body is the most essential part, directly influencing the valve’s performance, flow characteristics, and service life.

Valve Cover

The valve cover is the enclosed part of the valve, typically connected to the valve body to form a sealed space within the valve. Its main function is to protect the internal components of the valve from external impurities and ensure complete sealing when the valve is closed, preventing media leakage. The design and manufacturing quality of the valve cover significantly impact the overall performance of the valve.
