The hygienic mixproof butterfly valve is equipped with two plugs that separate incompatible media using two separate seals. It has a separate vent chamber with a spring-loaded valve.
When the valve is closed, i.e. the two media are separated, the vent valve remains open by means of a link.
In the event of a leak, the medium escapes from the vent chamber. When the valve is opened and the two media are allowed to mix or flow to the opposite connection, the vent chamber valve remains closed.

Cipriani Harrison hygienic butterfly valves are manufactured using a forging process.
Cipriani Harrison hygienic butterfly valves are available with various handle options, depending on customer needs and application requirements.
