Use The radiator valves are used in hot water heating plant for individual room or zone temperature control and limitation. They are basically recommended in all rooms, especially where heat gains or different temperature levels occur.

Mechanical design / technical design The flow rate can be preadjusted with an orifice. Full stroke is ensured irrespective of the preadjustment, which is made with the help of the protective cover. 1 Manual knob / protective cover 2 Sealing gland 3 Valve insert 4 O-ring 5 Reset spring 6 Orifice Features and benefits · The valves conform to EN 215. · The sealing gland can be replaced while the plant is under pressure (no tools required).
