Burkert Type 6519 Pneumatic Valve | 5/2 & 3/2 Way Pilot Solenoid Valve | 00132478 00133046

The Type 6519 Series of pilot-operated pneumatic solenoid valves manufactured by Chengyuan Hydraulic are premium, high-flow directional control elements engineered to fully match German Burkert technical standards. This series is universally relied upon for the pilot control of pneumatic actuators (such as double-acting or single-acting quarter-turn process valves). Focused on core high-demand part numbers—00132478, 00132728, 00133046, 00132475, and 00132476—Chengyuan delivers 100% original-place interchangeable compatibility in both standard G1/4 threaded ports and NAMUR interface layouts. Built for heavy-duty industrial automation, every single 6519 replacement valve undergoes 100% full-load simulated cycle testing and leakage analysis prior to shipping, ensuring robust sealing boundaries and lightning-fast response times.

• Seal Formulations: Heavy-duty NBR paired with reinforced Polyurethane (PU)

• Electrical Inputs: 24V DC, 110V AC, 230V AC (50-60Hz), utilizing Form A DIN 43650 industrial connectors

• Environmental Sealing: IP65 protection rating when properly mated with cable plug

• Holding Power Consumption: ~2W for DC versions (Highly efficient low-thermal coil design)

Key Technical Advantages:

• Innovative 5/2 to 3/2 Way Adaptability: Utilizing a specialized reversible seal-plate interface, a single valve can be rapidly toggled between a 5/2-way configuration (for double-acting actuators) and a 3/2-way format (for spring-return single-acting actuators). This modular approach provides ultimate field flexibility and significantly slashes warehouse spare-part SKU duplication for B2B distributors.

• Low-Friction Floating Spool Assembly: The internal spool is crafted from hard-anodized aluminum alloy sliding within specialized segment elastomeric seals. This design cuts dynamic friction to a bare minimum, enabling a smooth low-pressure pilot initialization at 2 bar while generating a robust service life exceeding tens of millions of cycles.

• Corrosion-Proof Polyamide (PA6) Enclosure: The outer housing is molded from high-impact, chemically resistant polyamide engineering polymers. Unlike conventional cast aluminum alternatives, this non-metallic body is highly resilient against aggressive atmospheres such as fertilizer chemical plants, pickling shops, and coastal marine environments, eliminating oxidation-induced spool binding.

• Low-Wattage High-Duty Solenoid Coils: The optimized internal magnetic circuit drops holding power consumption down to a mere 2W (for DC platforms). This incredibly low heat dissipation minimizes coil degradation over extended operational periods, preventing insulation breakdown and securing stable high-frequency actuation.

Application Areas:

• Process Plant Automation: Centralized pilot actuation for pneumatic ball, butterfly, or knife-gate valves across chemical, pharmaceutical, and water treatment loops.

• Material Handling & Pneumatic Conveying: High-frequency cylinder sorting and gate control on food processing and industrial packaging automation grids.

• Environmental & Power Engineering: Sequential logic distribution for pulse-jet fabric dust collectors and automated bag-house manifold systems.

Expert Maintenance Tips:

• Enforce Strict Intake Air Quality Guidelines: Although the Type 6519 exhibits moderate tolerance to debris, condensed moisture and abrasive pipe rust will quickly scar the internal elastomer seals. Always safeguard the valve intake line with an F.R.L. filtration cluster holding an absolute 5-micron or finer glass-fiber element, and empty the water traps periodically.

• Precise Torque and Gasket Alignment during NAMUR Mounting: When employing NAMUR subplate installation (prevalent in codes like 00132478), cross-verify that the face-sealing O-rings are perfectly seated inside their molded retainer recesses. Tighten the mounting fasteners evenly in an alternating sequence to prevent micro-deflections in the polymer base that cause boundary air leaks.

• Clear the Manual Override Post-Troubleshooting: The valve body houses a lockable slot-type manual override mechanism. During installation debugging or power outages, technicians can push and twist this dial with a flat-head screwdriver to force a mechanical shift. Always return the screw to its baseline ‘Auto’ position prior to system startup, otherwise, the valve will ignore electronic command signals from the main PLC.
