Caution: Make sure that screws are not too long otherwise the valve body may be damaged.
Note: These torques are valid if depth of the mounting screws is min. 1 x thread diameter. Make sure that screws in use
are capable to withstand applied torques. Lubricate screws slightly.
2.4 Admissible
forces
Forces from evacuating the system, from the weight of other components, and from baking can lead to deformation and
malfunctioning of the valve. Stress has to be relieved by suitable means, e.g. bellows sections.
