Three-Piece Flanged Ball Valve in Stainless Steel | Industrial-Grade High-Pressure Corrosion-Resistant Solution<\/div>\n
<\/div>\n
——<\/div>\n
<\/div>\n
Core Structure and Design Differences<\/div>\n
<\/div>\n
Unlike sanitary flanged ball valves, the three-piece flanged ball valve adopts asplit-body design(consisting of the valve body and left\/right valve covers), connected by high-strength bolts. It is specifically designed for harsh industrial conditions, featuring:<\/div>\n
<\/div>\n
\u00a0 1. Modular Maintenance: The valve cover can be disassembled without removing the pipeline, allowing direct replacement of the valve seat, ball, or seals, reducing maintenance costs.<\/div>\n
<\/div>\n
\u00a0 2. Heavy-Duty Design: The valve body thickness is increased by 20%, and the flange is reinforced (complying with GB\/ANSI\/DIN standards), with a pressure rating ofPN16-PN40.<\/div>\n
<\/div>\n
\u00a0 3. Non-Sanitary Applications: Suitable for petrochemical, power and energy, papermaking, and other industrial fields, handling particulate, high-viscosity, or corrosive fluids.<\/div>\n
<\/div>\n

<\/div>\n
\u00a0 2. Bi-directional Sealing Design<\/div>\n
<\/div>\n
\u00a0 \u00a0 \u00a0 \u2022 Double valve seats (upstream + downstream), achievingzero leakage (API 598 standard)for bi-directional flow.<\/div>\n

<\/div>\n
\u00a0 4. Flange Compatibility<\/div>\n
<\/div>\n
\u00a0 \u00a0 \u00a0 \u2022 Supports GB, ANSI 150\/300LB, DIN flanges, matching industrial piping systems.<\/div>\n
<\/div>\n

<\/div>\n
Typical Industrial Applications<\/div>\n
<\/div>\n
\u00a0 \u2022 Petrochemical Refining: Emergency shut-off valve for crude oil pipelines.<\/div>\n
<\/div>\n
\u00a0 \u2022 Power & Heating: Flow control in steam main pipelines.<\/div>\n
<\/div>\n
\u00a0 \u2022 Papermaking: Control valve for thick paper pulp.<\/div>\n
<\/div>\n
\u00a0 \u2022 Water Treatment: Acid\/alkali control in high-pressure reverse osmosis systems.<\/div>\n
<\/div>\n

DN100PN40Reinforced PTFE + GraphiteElectric actuator (explosion-proof)<\/div>\n
DN200 PN16 Metal + soft seal composite Hydraulic actuator (high torque)<\/div>\n
<\/div>\n
——<\/div>\n
<\/div>\n
Installation & Maintenance Tips<\/div>\n
<\/div>\n
\u00a0 1. Pre-installation Check: Clear welding slag from the pipeline, ensure flange faces are parallel and aligned, avoid overtightening bolts to prevent valve body deformation.<\/div>\n
<\/div>\n
\u00a0 2. Regular Maintenance: Inspect the valve stem packing gland every 6 months, replenish high-temperature grease (e.g., molybdenum disulfide).<\/div>\n
<\/div>\n
\u00a0 3. Emergency Handling: For internal leakage, adjust the valve seat preload spring or replace the seal ring first, without needing to replace the entire valve.<\/div>\n
<\/div>\n
——<\/div>\n
<\/div>\n
Differentiation Positioning: The three-piece flanged ball valve focuses onindustrial pressure resistance, wear resistance, and long lifespan, targeting harsh non-sanitary conditions, clearly distinguishing itself from sanitary valves’ “sterile, quick-disconnect, mirror-polished” attributes.<\/div>\n
