Abstract: A balancing valve is usable to adjust and control the flow of fluid in central heating networks, hot and cold utility water installations and in air conditioning and cooling installations. The valve (1) has a body (2) with an inlet connector pipe (3) and an outlet connector pipe (4). A seat (5) is positioned in the body and an opening (20) in the body in alignment with the seat is closable with a releasible cover (12). A stem (7) is rotatable by a knob (10) relative to the cover. Rotational movement of the stem is operative to axially move a head (6) connected to an adjusting ring (13) relative to the seat within the valve. Exemplary valve components are comprised of plastics.

Abstract: The invention provides a balancing valve. The balancing valve (1) is provided with a body (2) that has two connector pipes (3 and 4). In the body (2) a seat (5) is housed which is closed with a head (6) mounted on a stem (7) where the stem (7) is seated in a gland (9). Outside the gland (9) there is a knob (10) engaged with the stem (7). The head (6) is made of plastics and it is connected with an adjustment ring (12) which is made of plastics.
