A slanting seat in the valve body will be closed with or against the flow direction by a valve disk. The valve disk is connected with the piston by a stem. It`s dynamical sealing and guidance happens by a screw joint between valve body and pilot cylinder. The slanting valve design renders a highly flow rate by low dirtyness. Pressure actuated valves would be actuated with the a piston by a neutral pilot media (air, water, oil). It works in a pressure range from 0 bar up to the max. nominal pressure which you can see in the pressure table. The flow direction is fixed and signed on the valve.
