• Body Material: High-performance Polyamide (PA6) / Aluminum base

Key Technical Advantages:

• Rocker-Pilot Technology: Unlike conventional plunger designs, the 6519W utilizes a rocker-pilot principle, significantly enhancing tolerance to lubricated or slightly dusty air. This prevents spool sticking and “dead-zone” issues even in non-ideal air quality conditions.

• High Dynamic Flow Response: The 6.0mm orifice combined with an optimized flow channel allows for a QNn flow of 900 L/min. This ensures rapid actuation (under 0.5s) for large-scale pneumatic ball valves or butterfly valves.

• Low-Power Coil Design: The 24V DC model consumes only 2W. This low heat generation design extends insulation life and permits high-density modular installation in confined control cabinets without overheating.

• NAMUR Standard Compatibility: The mounting interface fully complies with international NAMUR standards, allowing direct bolting to pneumatic actuators. This eliminates the need for additional fittings, simplifying site plumbing and reducing potential leak points.

Application Areas:

• Process Control: Remote shut-off control for pneumatic valves in chemical plants.

• Water Treatment: Control for filter backwash valves and automatic dosing systems.

• Food & Pharma: Cylinder drives for packaging lines and cleanroom pneumatic door controls.

• Energy & Power: Power distribution for pneumatic actuators in flue gas desulfurization systems.

Expert Maintenance Tips:

• Minimum Operating Pressure: As a pilot-operated valve, a minimum system pressure of 2 Bar is required for reliable switching. At pressures below 1 Bar, the spool may fail to reset completely.

• Moisture Protection: During installation, ensure the cable plug gasket is properly seated. In humid environments, position the cable entry downwards to prevent condensation from traveling into the coil.

• Silencer Installation: It is highly recommended to install sintered bronze silencers on exhaust ports (Ports 3 and 5). This reduces noise and prevents external dust from being sucked back into the valve body.
