The punched valve seat serves to ensure high density, the damping piston prevents any valve vibration. It produces a flat control characteristic, , even at an increas-ing flow rate the set opening Pressure is for the most part maintained. This is achieved by the effect of the flow forces on the valve disk, whereby the valve continues to open as the flow rate version variants are available: Housing for pipeline installation with and without measuring connection. Valve cartridges for block installation. Various adjustment methods such as hand wheel, lead-seal capable, fixed, hand wheel with scale (with and without lock).
