FIELD: machine building.
SUBSTANCE: invention relates to flow regulators, particularly, to flow regulators with bowl-shape seat. Regulator consists of valve body to define fluid flow and valve seat, drive case engaged with valve body, control member arranged in drive case and adapted to displacement relative to valve body and valve seat for regulation of fluid flow at displacement between open position and closed position whereat said control member engages with valve seat, and spring articulated with control member to displace the latter to open position. Said control member has the surface directed to valve seat and furnished with recess. Recess can be reamed, or concave, or conical or have any other suitable surface.
EFFECT: higher reliability, perfected adjustment.
