The knife gate valve system DOMINO is preferably used in the field of water
treatment and process engineering. The valve is the right solution for media containing mud and fibers.
The knife gate valve seals pressure tight in both flow directions.
The user can choose among a variety of executions and actuators.
The design of the DOMINO knife gate valves fulfils the users’ highest requirements.
The maintenance-free COMPACT cross seal (double seal lip profile) guarantees tight shutoff and can be adjusted without interrupting the working process.
The self-cleaning effect is achieved by flush-out corners in the body and the cutting edge underneath the gate. Solids and fibres are cut by the cutting edge before tightening is done against the elastic seat. The guidance of the gate is interrupted on stroke length, thus dirt can be ejected.
Bidirectional shutoff is achieved by the lateral gate surfaces and the elastic seat which is integrated in the body. The seat is chambered and prestressed mounted.
The high finish of the guide- and sealing surface at both sides guarantees long service and tight shutoff.
The lateral guidance of the gate prevents the gate from fluttering in either of the flow directions or in throttle positions.
