Spring-loaded pressure relief valves for silo overfill protection

Ensure safety and prevent costly overfills with pressure relief valves that provide reliable, instantaneous response to abnormal silo pressures, safeguarding both structures and valuable materials during critical operations.

Regulates Pressure and Provides Overfill Protection

The Spring-Loaded Pressure Relief Valves VCP, brought to you by WAMGROUP, are engineered specifically for robust silo safety across various industries. Designed with a durable cylindrical casing and helical spring mechanism, these valves respond instantaneously to pressure changes, ensuring structural integrity by efficiently regulating excess or suction pressure. Ideal for applications ranging from ready-mix concrete and asphalt mixing to wastewater treatment and food processing, these valves are integral in producing treated wastewater, precast concrete slabs, asphalt mixtures, and processed food products.

With a flow rate capacity of up to 13,000 m³/h, they accommodate significant throughput demands. The VCP series is built for easy integration into existing production lines, featuring a lightweight design for effortless handling and quick installation. Fabricated in painted carbon steel or 304 stainless steel, they offer excellent corrosion resistance and are complemented by a stainless steel weather protection cover. These valves also comply with European Regulation (EC) No. 1935/2004 for food industry applications and offer optional ATEX certification.

Maintenance is straightforward with easily accessible components, while the option for inductive sensors enhances safety monitoring. With preset values for negative and excess pressure, the VCP valves are customizable to meet specific operational requirements, ensuring optimal silo protection and operational efficiency.

Benefits

  • Protects silo integrity by rapidly adjusting to pressure changes.
  • Facilitates diverse industry integration with customizable pressure settings.
  • Enhances operational safety with optional inductive sensor configuration.
  • Minimizes installation and maintenance time due to compact, lightweight design.
  • Supports regulatory compliance for food safety and explosive environments.
