Industrial Air Compressor Pressure Switch 220V 380V Regulating Valve

This pressure regulating valve is engineered to provide accurate control for air compressor assemblies, specifically targeting systems requiring a switching range between 0.5 and 0.8MPA. Suitable for European-style assembly bodies, this component ensures that air pressure remains within safe and efficient limits. The unit is available in both 220V and 380V configurations, making it a versatile choice for various workshop and industrial environments where specific voltage inputs are mandatory.

Technical Specifications and Build

The internal and external dimensions of this switch are designed to fit standard mounting requirements while providing robust protection for its electrical components. The physical build quality supports high-current operations without compromising safety or longevity.

Pressure and Voltage Ratings

The core functionality revolves around its ability to manage a working pressure of 5-8KG effectively. The switch box is clearly printed with maximum ratings, including a max voltage of 240V and a max pressure of 12 BAR (175 PSI), providing clear visual confirmation of its limits. It handles a maximum current of 20A, ensuring it can manage the power demands of typical compressor motors within its designated range.

Connection and Port Sizes

Installation is streamlined through standardised port sizes, including a 12MM connector with a 1/4 inch thread. The unit also features a 6MM exhaust pipe for pressure release and a pressure relief port with a 9.5MM outer diameter. These precise measurements ensure compatibility with existing piping systems without the need for complex adapters.

Durability and Cycle Life

Built for repeated use, this pressure switch is rated for a lifespan of 80,000 cycles. This high cycle count indicates a design focused on long-term reliability, reducing the frequency of replacements in busy workshops. The normally closed contact method adds a layer of safety, ensuring the circuit breaks automatically if pressure conditions deviate from the set parameters.

Operational Versatility

The dual-voltage capability allows this product to serve a wider range of machinery. Whether powering a smaller 220V unit or a heavier 380V industrial compressor, the switch adapts to the required input while maintaining consistent pressure regulation.

Industrial and Workshop Use

In professional settings, maintaining precise air pressure is vital for tool performance and safety. This switch facilitates that by cutting power at the upper limit of 0.8MPA and restarting at the lower limit of 0.5MPA. This automatic regulation prevents over-pressurisation and ensures a steady supply of compressed air for pneumatic tools.

Compatibility with European Assemblies

Designed with European-style assembly bodies in mind, the physical footprint and mounting style align with common industry standards. The compact packaging size of 185 x 100 x 110mm reflects the unit's space-efficient design, allowing it to be mounted in confined compressor housings.

Value and Maintenance

Investing in a component with clear specifications and a proven cycle life reduces downtime. The clear labelling on the switch box aids in quick visual inspections and troubleshooting.

Low Maintenance Design

The simple mechanical design minimises the need for frequent adjustments. Users primarily need to ensure that the connections at the 12MM and 6MM ports remain tight and free from debris. The robust casing protects the internal mechanism from dust and minor impacts common in workshop environments.

Reliable Performance Summary

With its specific pressure range, high current capacity, and extensive cycle life, this pressure regulating valve offers a dependable solution for air compressor maintenance and assembly. It replaces guesswork with defined metrics, ensuring your compressor operates within its intended safety margins.
