VCP Pressure Relief Valves consist of a cylindrical casing with a bottom flange to be connected with a spigot welded on the silo roof, a disc shape inner steel lid for negative pressure operation held in position by a central spring rod, an outside steel ring for excess pressure kept in position by three spring rods, gaskets, and a weather protection cover.

You can trust the safety of your workers and the maintenance of your bin structure to the reliability of Deca VCP Pressure Relief Valves. Our valves are manufactured to high quality standards and are backed by Deca’s 50 years of bulk material handling applications experience. Combined with Deca’s world class applications support your company can achieve unmatched performance and peace of mind. That’s why hundreds of thousands of bins and silos are protected with the VCP. 

Why are they Necessary

• Tight safety regulations in industrialized countries have regulated the positive and negative pressures exerted on bins and silos for many years. Pressure relief valves are a key part of meeting those regulations and keeping the workplace safe. In fact, they are the last line of defense against the safety hazards that are caused when excess pressure is placed on bin walls.
• Sudden changes in bin pressure must be dealt with immediately and DECA VCP valves are engineered to do just that. These specially designed, two-way valves allow air to pass quickly and efficiently between the bin and the surrounding environment to make sure that the air pressure inside your hopper is kept as close to equal as possible.
• Although, under ideal circumstances, pressure relief valves should never have to be operated, when and if they do the safety of your work site depends on these important components. That’s why it’s so important that they work the first time every time.
• To ensure that they do Deca valves are engineered with time tested designs, and built to meticulous quality standards.
