Hippo Valves

The SIRIS Hippo valve is a convenient self-cleaning scum removal solution designed to remove surface grease, fat and floating debris from circular primary and humus tanks.

Installed below the tank outlet weir level, the Hippo valve opens on each scraper bridge rotation, releasing surface scum from the tank and eliminating grease build-up.

A fully-adjustable design makes it quick and easy to fit the valve according to your requirements and we can vary the point at which it opens and how long it remains open for to suit your needs. We recommend allowing the valve to be held open until the rotating scum board has passed to allow the valve seat to be ‘washed’, removing the need for manual cleaning.

The Hippo is simple to install and is virtually maintenance-free, making it a convenient replacement for your existing scum removal system.
