Butterfly valves ZD are intended for smooth regulation of a consumption of gas or air. Butterfly valves establish in systems of gas supply in GRP, on the gas pipeline in front of package boilers and before gas torches both on industrial and on municipal objects.
Structurally the butterfly valve ZD consists of the following main parts: case, limb, lever, clamp and disk. The case is a piece of a pipe in which there is a rotary disk fixed on a shaft. The shaft turns by means of the lever on the necessary angle of opening. The angle of opening of the gate is fixed by means of a clamp in limb openings. Openings for fixing of the lever on a limb are put through each 5 degrees. Regulation of the passed environment is carried out by overlapping of the section through passage of the case by a disk on the set angle of opening. Butterfly valves in usual execution have the manual drive, but the electric drive by request can be installed. Butterfly valves from DN15 on DN32 have muftovy accession to the pipeline, and gates from DN40 on DN500 flange accession.
