Shut-off valves can be either throughway or angle valves, bolt and with or without flanges. Flangeless valves are equipped with connector pipes with dimensions in accordance with PN-80/H-74219 norm and with DIN 2448 standard (marked additionally with symbol: /D). Differences in dimensions are showed in the tables. All shutoff valves have an unslidable spindle. Valves’ leaktightness in closure position is secured by P.T.F.E. gasket pressed down by the valve head. The casing is made from welded high resistance P355 steel. When the valve is fully open (by turning the handwheel left as far as possible), the inflow of the medium to the stuffing box is cut off, which makes it possible to replace the spindle gasket in a valve that is under pressure. If frequent opening and closing of the valve is not required, semi-hermetic valves with a cap can be installed, in which the cap covers tightly the upper part of the spindle and the gland seal. After reversing the cap, it can be used as a handwheel. For valves with DN 10 – 200 mm, the flow of the medium should be directed under the valve head, whereas for valves with DN 250 and 300 mmm, the flow of the medium should be directed above the valve head. Valves with DN 250 and 300 mm are equipped with side conduits with pressure reducing valves.
