Abstract:
A fluid control valve includes a cylindrical housing with at least one opening through a housing wall, a cylindrical main valve axially movably arranged inside the housing for controlling a fluid flow through the at least one opening and a main valve spring member acting on the main valve. The main valve includes a base wall defining a fluid control volume and fluid main volume in the cylindrical housing. The base wall includes an opening for fluidly connecting the fluid control volume with the fluid main volume. The fluid control valve further includes a pilot valve positioned at the base wall opening, which pilot valve is moveably arranged for controlling a fluid flow through the base wall opening, and an electro-mechanical actuator configured to act on the pilot valve for controlling the main valve via the pilot valve. A method for adjusting the axial position of a cylindrical main valve of a fluid control valve is also provided.
