Smooth Operation and Fast Response

Hearken Namur solenoid valve utilizes an internal pilot structure and a highly responsive coil, enabling rapid response to remote commands with only a minimal current signal. Furthermore, the internal sliding column structure of the Hearken Namur solenoid valve is lubricated with imported grease, resulting in low friction and smoother operation, significantly improving the efficiency and process accuracy of your automation system.

Long-Term Stable Operation

The Hearken Namur air operated solenoid valve, featuring Class F coil insulation and thermoset BMC-coated coils, offers high-temperature resistance, high insulation, and chemical corrosion resistance. This effectively reduces the risk of coil overheating, resulting in aging, burnout, or short circuits. This cost-effective design improves the safety of your automation system and ensures 100% stable, continuous operation even in high-temperature operating conditions.

Suitable for Harsh Industrial Environments

Hearken Namur pneumatic solenoid valves are optimized for the protection and explosion-proof performance you need in heavy-duty industrial environments. We offer explosion-proof Namur valves with up to IP65 certification and Ex mb I/II T4 certification. These valves effectively prevent the intrusion of water mist and dust in complex working conditions, operate stably in flammable and explosive environments, and effectively prevent sparks, protecting on-site workers.

Production

Namur Solenoid Valve Production Process

Raw Material Testing

Every raw material used in Hearken namur connection for solenoid valve undergoes testing for material composition, hardness, and corrosion resistance to ensure high quality.

Processing

Each Hearken Namur solenoid valve component undergoes a series of CNC precision machining, coil winding and potting, precision polishing of the slide and core, and seal manufacturing before being assembled into a complete unit.

Complete Unit Testing

After applying imported grease to the operating parts and sliding surfaces, the assembled Hearken Namur solenoid valve undergoes a series of performance tests (including response testing, air tightness testing, resistance testing, insulation resistance testing, and protection level testing). The valve is then factory-tested to ensure it is ready for immediate installation upon receipt.

FAQ

A: It allows the Solenoid Valve to bolt directly onto the actuator side, eliminating the need for external tubing.

A: Yes, many modern NAMUR valves feature a convertible design via an adapter plate. However, always confirm with the specific model’s manual.

A: DC24V is standard for safety; AC110V/220V are common for existing plant wiring.

A: Yes, it allows you to test the valve manually without electrical power.

A: It is normal for coils to heat up when energized. For cooler operation, choose Low Power (energy-saving) coils.
