Frequent jamming or sealing failures of the ash warehouse pressure relief valve can cause system pressure fluctuations and dust leakage, which not only affects equipment safety but also increases maintenance costs. Head Powder's customized pressure relief valves are specifically designed to address such issues, ensuring that every pressure release is accurate and reliable.

Product description

The pressure relief valve is a key safety component in the ash silo pneumatic conveying system, used to automatically open and release pressure when the tank pressure exceeds the set value, protecting the equipment from overpressure damage. Head Powder can provide non-standard customization services based on customers' specific working conditions, interface dimensions, and discharge requirements. The product has a compact structure and responsive operation, suitable for various powder material scenarios such as fly ash, cement, and mineral powder.

Product features

  • Rapid response: The diaphragm or spring mechanism design can open instantly when pressure exceeds the limit, releasing pressure promptly.
  • Reliable sealing: Made with wear-resistant sealing materials, long-term use prevents leakage and reduces dust leakage.
  • Corrosion and wear resistance: Key components are made of stainless steel or relatively high-strength alloys, suitable for environments with high dust and high temperature differences.
  • Flexible customization: Non-standard designs can be made according to user requirements for opening pressure, interface flange standards, and installation space.
  • Easy maintenance: modular structure, requiring no complex tools for routine inspections and component replacement.

Product prices

Pressure relief valves are customized products, and their price depends on specific specifications, material requirements, and opening pressure parameters. If a unified price cannot be provided, you may contact Head Powder sales engineers to obtain an accurate quote after providing detailed working conditions.

Service commitment

Frequently Asked Questions about Model Selection

The most frequently asked questions before placing an order. If you can't find the answer, you can leave a message or consult online.

Material name and characteristics (particle size, bulk density, moisture content, whether fragile, worn, and moisture-absorbent), conveying volume, conveying distance (horizontal/vertical), number of start and end points, and whether there are explosion-proof or cleanliness requirements on site. The more complete the information, the closer the quote is to the final version.
Yes, you can. The company has established a comprehensive pneumatic conveying testing center, supporting preliminary testing of materials and issuing measured data (air consumption, wind speed, wear, and crushing rate), which then determines the model and system configuration.
Transmission equipment and pipeline fittings are self-produced, with self-developed automation control cabinets. Solution design, manufacturing, electrical control, installation, and commissioning are all integrated, with no subcontracting and a clear responsibility interface.
