Valves for Substrate and Biogas Valves for Substrate and Biogas GEFA Valves for Biogas plants fulfils the users' highest requirements DOMINO gate valves: High security by cutting effect with the closing procedure KG butterfly valves: High life span by solid seat system P R O C E S S T E C H N I K G M B H 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.
