FIELD: machine building.
SUBSTANCE: series (11) of valves, including several types (A, B, C) of valves of various standard size, besides: each type (A, B, C) of valve from series (11) of valves includes linearly moving locking element (19) valve, to which valve seat (17), closing spring (20) and valve drive (21) are related, valve drive (21) of all types (A, B, C) of valves is unified and provides unified maximum stroke (h), valve series (11) includes at least two types (A, B, …) of valves, closing springs (20) of which have different characteristic curves (I, II), various closing springs (20) are made with application of various locking forces when valve (19) shutoff members are installed on valve seats (17), various closing springs (20) are made with application of preferably identical locking forces at openings (19) of valves in open position.
EFFECT: invention relates to a structural range of valves, primarily to a design series of gas valves having different standard sizes.
