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 fibers are cut by the cutting edge before tightening is applied against the elastic seat. The guidance of the gate is interrupted along the stroke length, allowing dirt to be ejected. Bidirectional shutoff is achieved by the lateral gate surfaces and the elastic seat integrated into the body. The seat is chambered and mounted with prestress. The high-quality finish of the guide and sealing surfaces on both sides ensures long service life and tight shutoff. The lateral guidance of the gate prevents fluttering in either flow direction or in throttle positions.
