Gteek Launches P355N Carbon Steel Flanged Ball Valve

Industrial pipeline systems require valves capable of withstanding extreme temperature variations while maintaining reliable performance across diverse fluid media. GTeek's newly introduced WK7a series carbon steel flanged ball valve has been engineered specifically to meet these rigorous demands.

The PN16-rated carbon steel ball valve is designed for water, air, and other fluid applications compliant with EU Directive 97/23/EC Group 2. Its core strength lies in the P355N carbon steel valve body and stainless steel ball, ensuring stable operation within a temperature range of -20°C to +160°C and pressures up to 16 bar.

Product Features and Technical Specifications

The WK7a series offers size options from DN40 to DN200 with EN 1092-1 B1 flange connections for simplified installation and maintenance. Key specifications include:

• Valve body material: P355N carbon steel with excellent weldability and low-temperature toughness, ensuring safety under high pressure and cold conditions
• Ball material: SS 304 stainless steel with superior corrosion resistance for multiple fluid media
• Sealing material: PTFE+C compound offering high-temperature resistance and chemical stability
• Stem sealing: Dual PTFE ring and EPDM O-ring configuration for enhanced reliability
• Design characteristics: Full-bore design minimizes flow resistance; anti-blowout stem improves safety; DIN 3202-compliant spacing facilitates maintenance
• Coating: RAL 9004 blue paint coating (5-15μm thickness) providing corrosion protection

Material Selection and Performance Advantages

The WK7a series demonstrates meticulous material selection. The P355N carbon steel valve body delivers strength and durability under high pressure, while the SS 304 stainless steel ball provides exceptional corrosion resistance across various media. PTFE+C sealing ensures consistent performance under diverse temperature and pressure conditions.

Industrial Applications

The valve's robust performance makes it suitable for multiple sectors:

• Water treatment: Flow control in water management systems
• HVAC systems: Regulation of hot/cold water in temperature control applications
• Industrial piping: Management of oils, gases, and chemical fluids
• Food and beverage: Process control in food production environments

Comparison with Cast Iron Alternatives

While GTeek also manufactures PN40-rated cast iron flanged ball valves for water treatment applications, the carbon steel variant offers superior strength and weldability for high-pressure, high-temperature environments. Cast iron may demonstrate better corrosion resistance in specific media, requiring careful selection based on operational parameters.

As industrial automation advances, valve performance requirements continue to escalate. The WK7a series carbon steel flanged ball valve represents a solution combining material excellence, precision engineering, and versatile applications, positioning it as a reliable component for demanding fluid control systems.
