Multiple purpose and directional valve - has valve element running length of housing to form control arrisses at pipe connections

摘要

The multi-purpose valve can direct several streams in parallel, opposed, sequential cross of auxiliary manner with heat exchange possibility. A valve element (14) runs the length of the valve housing (12) to lay on guide surfaces via seals (50, 52, 54, 56). The housing (12) has a series of conduit connections (40, 42). The value element (14) can be adjusted and set along the longitudinal direction of the housing (12) to form control arrises. The housing can be formed from five separate pieces (18, 20, 22, 20, 18). The end (18) and intermediate (10) pieces are mirror image, of each other. Central elements (28, 48, 30) have a groove around their circumferences to receive seals (50, 52, 58, 56).
