For installation in a valve housing for the limitation device, for the field of heating the thermostatic valve which is provided, which is provided as well as the sanitary sector of advance of the blocking valve

摘要

The invention relates to a for installation in a valve housing (1) for the intended quantity of the valve housing (1) from a supply (2) to an outlet (3) vane with a medium, in particular, water, with respect to flow rate and pressure difference within a prescribed working range and independently of the respective initial pressure within this range. The device has a valve spindle (6) and a valve cone (14), which under the effect of alignment with a in the valve housing (1) valve seat (4) provided on the latter to - can be moved toward and is mounted, wherein between the, the valve cone (14) facing end (6a) of the valve spindle (6) and the valve cone (14) a this coupling device (10) is provided for measuring the differential pressure. The present invention further relates to a thermostat valve is provided for the heating unit as well as a sanitary technology, which is provided for the stability range of advance of the blocking valve.
