Forged Ball Valve – Fire-Safe Design

Our premium forged ball valve is engineered for demanding industrial applications where safety, durability, and performance are critical. Designed in accordance with international standards, this valve ensures reliable operation under high pressure and temperature conditions.

Key Specifications & Materials:
• Body Material: ASTM A105N forged carbon steel, providing excellent strength, toughness, and resistance to pressure-related deformation
• Ball: F316 stainless steel with Electroless Nickel Plating (ENP), enhancing corrosion resistance, surface hardness, and wear performance
• Stem: Duplex stainless steel F51, offering superior mechanical strength and excellent resistance to stress corrosion cracking
• Seat: PEEK (Polyether Ether Ketone), a high-performance thermoplastic known for outstanding thermal stability, chemical resistance, and low friction
• O-Ring: HNBR (Hydrogenated Nitrile Butadiene Rubber), ensuring excellent sealing performance under high temperature and aggressive media conditions

Design Features:
• Fire-Safe Design: Engineered in compliance with international fire safety standards, ensuring sealing integrity even in extreme fire scenarios
• Anti-Static Device: Prevents static charge buildup between ball, stem, and body, enhancing operational safety in hazardous environments
• Anti-Blowout Stem: Internal stem design prevents accidental ejection under pressure, significantly improving safety during operation
• Precision Machining: Tight tolerances and high-quality finishing ensure smooth operation and extended service life
• Full Bore / Reduced Bore Options: Available to meet various flow requirements and system designs

Surface Treatment:
• Coating: High-quality international brand coating system applied for superior corrosion protection and long-term durability
• Coating Thickness: Controlled to meet project specifications (customizable per client requirements and standards), ensuring consistent protection performance

Applications:
Widely used in oil & gas, petrochemical, power generation, chemical processing, and other critical industrial systems where reliability and safety are essential.

At GMK VALVE, we are committed to delivering precision-engineered valve solutions that meet global quality standards and exceed customer expectations.
