Pressure Relief Valve

Protecting Silos from Over Pressurisation

Pressure Relief Valve

ConSpare PRV 350 Pressure Relief Valves are designed to protect silos from over pressurisation (vacuum) encountered during powder filling and emptying.

The valve complies with guidelines issued by the Health and Safety Executive (HSE) in their recent publication 'Guidance to Prevent Over Pressurisation of Storage Silos During the Delivery of Powder'.


Capable of venting 13000m³/hour in an over pressure situation and 5000m³/hour under vacuum, the valve has been fully tested and certified under controlled conditions witnessed by the HSE. The PRV 350 is available in a number of different materials and gasket combinations making it suitable for a wide range of applications. A range of upstands and adaptors, including a hinged version for ease of maintenance, is available for new or retrofit applications.
