The invention relates to a diaphragm for a diaphragm valve. The diaphragm has a functional region and a fastening portion, which surrounds the functional region. In a relaxed state, the functional region includes a central portion, which protrudes on a wet side of the diaphragm; —a lateral portion, which protrudes on a dry side of the diaphragm, the lateral portion being curved, at least in parts, toward the dry side of the diaphragm; and an intermediate portion, which is arranged between the central portion and the lateral portion and is curved, at least in parts, toward the wet side of the diaphragm.

Diaphragm and diaphragm valve

The invention relates to a method for producing a diaphragm for a diaphragm valve. The method includes the steps of conveying a plastics melt through at least one feed channel into a mold cavity which is delimited by a first mold and a second mold; moving the first and second molds toward one another; removing the at least one diaphragm from the mold cavity; and cutting off a sprue from the at least one diaphragm removed from the mold cavity.

Method for producing a diaphragm for a diaphragm valve

An assembly including a valve unit, a suck-back unit and a valve body is proposed, the valve body including a first channel portion which leads into a first chamber having a valve seat; the valve body including a second channel portion which connects the first chamber to a second chamber; the valve body including a third channel portion which leads away from the second chamber; the valve unit including a first actuator; the first actuator closing a connection between the first channel portion and the second channel portion when the first actuator is pressed against the valve seat; and the suck-back unit including a second actuator, the second actuator, when retracted inside the second chamber, sucking back a fluid in the third channel portion towards the second chamber if the connection between the first channel portion and the second channel portion is closed.
