AWH Double Block and Bleed Valves (Leakage Valves) for food and beverage industry.
The AWH Double Block and Bleed (leakage) butterfly valve is designed to be used in applications where mixing of liquids must be prevented.
Use of standardised components from our butterfly valve range permits great variability with respect to connections, gasket or sealing materials, and modifications keeping spare-parts stock to a minimum.
The leakage valve con be operated by an actuator or manually, and is fitted as standard with auxiliary flushing valves, one leakage and one flushing. The auxiliary valves can be activated in sync or in isolation. Thanks to their design, both valves are easy to clean and completely isolated when closed.
The auxiliary valve’s sealing piston is positioned almost flush in the through-flow pipe, so contamination is not possible at this point.
