It's amazing what can happen when your team isn't satisfied with "good enough." Get ready for the DV-5A - our new and improved deluge valve. We streamlined the original DV-5, creating an even simpler design with a lower pressure drop and higher pressure rating up to 300 PSI. Plus, with a reduced footprint and integrated alarm port, installation and maintenance are easier than ever.
