Feature (F)、Advantage (A)、Benefit (B)

1. Raw Material:

• F: : Body and dual valve cores integrally forged from AISI 316L low-carbon stainless steel, noseams or impurities; full traceability of heat numbers and material certificates; cold-rolled +bright annealing.
• A:: No intergranular corrosion risk; resists weak acids/bases and chloride corrosion; withstandsthousands of CIP/SIP cycles without deformation; no harmful leaching; stable mechanical properties; high strength for double-seat structure; high dimensional accuracy (OD tolerance+0.05 mm).
• B: Solves pain points of conventional valves (weld cracking, material inhomogeneity,cross-contamination risk). Meets FDA/GMP/ASME BPE aseptic standards. Extends service life,reduces compliance risk and operating costs.

2. Processing Technology:

• F:  Integral forging without welds; flow path ultra-mirror electrolytic polishing (Ras0.2 um); valvecore sealing surfaces precision ground; concentricity tolerance 0.01 mm; flow path optimizedby fluid dynamics.
• A: Extremely high fit between dual cores and seats; seals do not shift or wear over longoperation; ultra-smooth flow path with no media adhesion or cleaning dead zones; eliminatesmicrobial growth and cross-contamination; reduces fluid resistance.
• B: Solves gaps, cleaning dead zones, and cross-contamination issues of conventionalmix-proof valves. Simplifies cleaning validation, reduces cleaning time by >60%, ensures asepticcompliance, lowers audit risk.

3. Structure Feature:

• F: Clamp type: 4-way flow path + double-seat linear stroke; clamp connections; compactintegral forging; built-in drain port and channel; fluid-dynamically optimized.Weld type: 4-way double-seat linear sealing; weld ends; built-in leak detection chamber; dualcores move synchronously; full rounded dead-leg-free flow path.
• A: No dirt-trapping gaps, cross-contamination, or residue dead legs. Allows smooth high-flowpassage for two fluids. One valve replaces multiple valves for 4-way switching and dual isolation,saving space and cost. Weld type leak detection chamber enhances safety.
• B:  Avoids the need for multiple valves, complex piping, and cross-contamination risks. Ensuresbatch consistency and sterility. Reduces unplanned downtime and piping costs.

4. Core Accessory Feature:

• F:  Clamp type: Standard sanitary clamp connection, tool-free assembly/disassembly (30 s).Intelligent actuator with position feedback, remote control, fault alarm. Internal/external mirrorpolish.Weld type: Standard sanitary weld connection, reliable seal, dead-leg-free. Intelligent actuatorwith smart positioner for precise adjustment, position feedback, remote control. Double-seatdouble seal + leak detection chamber - 100% mix-proof.
• A:  Clamp type: 70% faster disassembly than welded; withstands high-frequency CIP/SIP. Intelligent actuator reduces human error, supports PLC remote control.Weld type: Permanent, contamination-free connection suitable for long-term asepticpipelines. Smart positioner achieves +1% accuracy and <0.5 s response time.
• B: Solves pain points of conventional mix-proof valves (poor automation, low hygienic grade,no intelligent feedback). Greatly improves aseptic safety and automation, reduces maintenanceand compliance costs, supports digital and smart upgrades.

5. Seal Ring Feature:

• F:: FDA/GMP certified food/pharma grade modified PTFE/EPDM double seals (silicone optionalfor clamp type). Embedded anti-misalignment, anti-penetration design. Ultra-precision sealingsurfaces. Weld type may use square diaphragm for higher reliability.
