Abstract: A controllable two-way valve for pressure and/or flow control uses a cup-shaped piston, the bottom of which forms a large effective surface area exposed to a control flow through a slit which cooperates with an edge of the slider also serving to define the main flow cross section between an inlet and an outlet. A stationary compensating piston within this slider vents the interior of the slider and a control valve set connected to a spring chamber through which the control flow passes regulates the pressure applied to the slider in the spring compartment.

Abstract: A multi-stage regulating valve is provided with a cylinder and an adjusting piston guided inside it to which a regulating pressure can be applied from one side and a return force from the other. Depending on the regulating pressure, the piston keeps at least one outlet aperture in the cylinder wall closed or partly or fully opens it and thus closes off a connection to the side of the piston to which the regulating pressure is applied or partly or fully opens it via the outlet aperture. To provide a multistage regulating valve which can alter the regulating characteristics over a wide range depending on the position of the piston even without the use of several return components, the piston consists of at least two partial pistons to which the regulating pressure can be applied, where the force of the return component can be applied to a first partial piston, whereby a follower interconnects the partial pistons in such a way that a return force is exerted on the second partial piston or other partial pistons via the first partial piston and the follower. The cylinder has at least one stop for the second or other partial pistons limiting the movement of the second or other partial pistons under the effect of the regulating pressure and against the action of the return component. The first partial piston is unaffected by the stop and remains movable against the return component if the regulating pressure increases further.
