Leading China DN50 SS316 Wafer Butterfly Valve Factory

Welcome to FTJ Valve, your direct and dependable China DN50 SS316 wafer butterfly valve factory. We specialize in engineering and manufacturing premium-grade stainless steel 316 (CF8M) flow control solutions for demanding corrosive environments. Our 2-inch (DN50) wafer butterfly valves are tailored to deliver exceptional sealing integrity, long operating lifespans, and zero maintenance in chemical processing, marine engineering, food & beverage, and pharmaceutical piping systems worldwide.

High-Performance DN50 Stainless Steel 316 Wafer Butterfly Valves

Selecting the right valve manufacturer is essential when handling aggressive fluid media, elevated temperatures, or strict sanitary standards. As a certified dn50 ss316 wafer butterfly valve factory, FTJ manufactures all valve components using high-grade austenitic SS316 (CF8M) alloy. Compared to standard SS304 or ductile iron, SS316 contains molybdenum, granting superior resistance to pitting, crevice corrosion, and chloride-rich environments.

Our DN50 wafer-type design features an ultrathin, lightweight body that fits effortlessly between standard international pipe flanges (including ANSI B16.5 Class 150, EN1092-1 PN10/PN16, and JIS 10K). The streamlined valve disc minimizes flow resistance and pressure drop while maintaining a tight, bi-directional bubble-tight seal under severe operating conditions.

Key Technical Features & Manufacturing Capabilities

• Superior SS316/CF8M Body & Disc: Precision investment casting ensuring high mechanical strength, chemical resistance, and smooth surface finishes.
• Resilient & Sanitary Seats: Available with high-purity PTFE, RTFE, EPDM, NBR, or Viton (FKM) seat liners to match specific chemical and thermal requirements.
• ISO 5211 Direct Mounting Pad: Facilitates seamless integration with manual hand levers, gear operators, pneumatic actuators, or electric motorized actuators for automated process control.
• Zero-Leakage Guarantee: Bi-directional sealing capability engineered to prevent backflow and fluid contamination across all standard operating pressures.
• Pressure & Temperature Ratings: Rated for working pressures up to PN16 / Class 150, capable of withstanding media temperatures from -20°C to +180°C (depending on seat material selection).
