Coperion, a compounding & extrusion, materials handling and service provider, with branches in North and South America, has introduced the new Coperion ZZB hygienic compact stainless steel rotary valve, developed specifically for small capacities and high sanitary needs. It is therefore suitable for operations in the food, pharmaceutical and chemical industries.
The interior and exterior polished surfaces prevent undesired product deposits. With the standard extraction device, the rotor can be easily removed from the housing. Easy-to-open tri-clamp flange connections at both inlet and outlet simplify installation and maintenance. The ZZB is available in 3 and 4-inch sizes. The standard ZZB offers pressure differential up to 3 or 15 psi(g) as an option, and is suitable for handling products to 212°F. The valve is constructed from a solid piece of AISI 316L stainless steel and can be easily disassembled, cleaned and reassembled.
