FIELD: valving systems.
SUBSTANCE: diaphragm valve comprises housing with lid, cross-piece, flanges, and two-layered flexible diaphragm provided with the drive. The layer of the diaphragm that faces the cross-piece is chemically stable material whose adhesion strength is equal to zero and is tightly connected to the top layer of the diaphragm over periphery. The drive of the valve is rigidly connected with the top layer of the diaphragm.
EFFECT: enhanced maintainability.
