Nominal Size: 4 Inch (DN100)
Face-to-Face Dimension: Compliant with API 609 / ISO 5752 (~52 mm / 2.05 in)
Flange Compatibility: Dual-certified for ANSI Class 150, PN10, and PN16
Body & Disc Material: Premium Grade SS304 / SS316 Stainless Steel
Actuation Type: Heavy-Duty Manual Gear Operator with Handwheel
Seat Material: PTFE / EPDM (Bubble-Tight Zero-Leakage Seal)
Corrosion Resistance: Full stainless steel construction withstands harsh chemicals, wastewater, food processing, and marine environments.
Space-Saving Wafer Design: Ultra-short face-to-face dimensions reduce pipeline weight and lower shipping/installation costs.
Smooth Operation & Precise Flow Control: The self-locking worm gear reducer minimizes operating torque and prevents back-driving during mid-stroke throttling.
Direct B2B Manufacturer Supply: We provide OEM/ODM customization, full CAD/3D dimension drawings, material test certificates (MTC), and volume discounts. Contact us today for a competitive 4" butterfly valve quote and technical catalog!
As a leading industrial valve manufacturer in China, FTJ Valve specializes in providing high-performance, corrosion-resistant, and durable flow control solutions for global industrial buyers. When sourcing compact yet robust shut-off and throttling solutions for industrial piping systems, understanding the precise 4 inch stainless steel gear operated wafer butterfly valve dimensions is essential for seamless installation, maintenance, and long-term pipeline integration.
Our China 4 inch stainless steel gear operated wafer butterfly valve dimensions are strictly manufactured in accordance with international design standards, including API 609, ASME B16.34, EN 593, and ISO 5752 (Face-to-Face).
Standard 4-inch (DN100) gear-operated wafer butterfly valves generally feature the following specification parameters:
Nominal Pipe Size (NPS): 4 Inch / DN100
Pressure Rating: Class 150 / Class 300 / PN10 / PN16 / PN25
Face-to-Face Dimension: Complies with API 609 / ISO 5752 short series (approx. 52mm / 2.05 inches)
Body & Disc Material: High-grade Stainless Steel (ASTM A351 CF8 / CF8M / CF3M / 304 / 316 / 316L)
Seat Material: PTFE / RPTFE / EPDM / NBR / Metal-to-Metal
Top Flange Mounting: ISO 5211 standard for easy actuator assembly
Operation: Heavy-duty worm gear operator with handwheel and position indicator
For exact bolt hole circle diameters, center-to-top heights, gearbox dimensions, and customized CAD/3D technical drawings, our engineering department provides comprehensive technical datasheets tailored to your specific project needs.
Superior Corrosion Resistance: Constructed from premium 304 or 316 stainless steel, these valves excel in harsh environments, including chemical processing, seawater desalination, wastewater treatment, and food/beverage manufacturing.
Effortless Manual Control: The manual worm gearbox significantly reduces torque requirement, enabling smooth, precise, and low-effort operation even under high differential pressure conditions.
Space-Saving Wafer Design: The compact wafer-style body fits snugly between pipe flanges using through-bolts, offering a lightweight, cost-effective, and space-saving alternative to bulky gate or globe valves.
Reliable Zero-Leakage Sealing: Engineered with precise machining, our valve seats deliver tight shut-off performance, preventing fluid contamination and minimizing system pressure drops.
At FTJ Valve, we combine decades of manufacturing expertise with rigorous quality control systems (ISO 9001, CE, API certified). Every single unit undergoes 100% pressure testing (shell and seat tests) prior to shipment to ensure reliable field performance. Whether you are an industrial distributor, EPC contractor, or system integrator looking for custom OEM dimensions, competitive factory-direct pricing, or fast global delivery, FTJ Valve is your trusted partner.
