Pressure control valves Back pressure regulators UV 5.5 Universal valve for small and medium flow rates Page No. UV 5.5/2.1.214.1 - Standing 17.03.2021 MANKENBERG GmbH | SpenglerstraUe 99 | D-23556 Lubeck www.mankenberg.de | Tel. +49 (0) 451 - 8 79 75 0 Technical Data Connection DN Connection G Inlet pressure Kvs value Temperature Medium * max. pressure at reference temperature -10 - +50°C Self-acting back pressure regulators are simple control valves offering accurate control while being easy to install and maintain. They control the pressure upstream of the valve without requiring pneumatic or electrical control elements. The UV 5.5 back pressure regulator is a spring-loaded proportional control valve for universal application at small and medium flow rates. The valve body and medium-wetted internal parts are made of stainless steel 316L featuring excellent corrosion resistance. The valve cone is fitted either with a metallic or a soft seal. The inlet pressure to be controlled is balanced across the valve seat by the force of the valve spring (set pressure). If the inlet pressure rises above the set pressure, the valve opens. With decreasing inlet pressure the valve control orifice reduces, when the pipeline is depressurised, the valve is closed. Rotating the adjusting screw clockwise increases the inlet pressure. These valves are no shut-off elements ensuring a tight closing of the valve. In accordance with DIN EN 60534-4 and/or ANSI FCI 70-2 they may feature a leakage rate in closed position in compliance with the leakage classes III or V, optional IV.
