There are two basic types of balancing valves - with and without drains. In cooling and heating systems as well as domestic water systems, balancing valves are used for accurate hydronic balancing (distribution of heat flows in the system) in a wide range of applications. The desired flow rate can be preset as required. The non-draining option offers valve closure. The drain version has a drain option in addition to closing.
Central heating systems, water heating systems and cooling systems need to be balanced. Valves are equipped with measuring inserts. Internal threads on both sides of the valve body serve for mounting. The handle is made of durable plastic. Manual balancing valves are manufactured mostly in DN 15 - 50, pressure class PN 20.
