Portfolio expansion: pressure reducing valve DM 152V with electro-pneumatic actuation according to ASME BPE The DM 152V pressure reducing valve comfortably meets the most demanding hygiene standards. Thanks to its external stem guide, this angle valve has virtually no dead space; the materials are FDA and USP Class VI-compliant. The available surface finish ranges from medium-contact Ra ≤ 0.38 µm to Ra ≤ 0.76 µm on the outside (electropolished). 👉 Our portfolio has been expanded to include an electro-pneumatic control system in accordance with ASME BPE. Key benefit: ✔️ In the event of a diaphragm rupture, the fluids do not mix ✔️ Precautionary and safety function The process medium and the gas for pressure control are separated by an additional chamber in the control system, offering you maximum process reliability. A plug in the chamber facilitates leak testing. Overview of new features: ✔️ External stem guide ✔️ Acc. to ASME BPE ✔️ FDA- and USP Class VI-compliant materials ✔️ Safety chamber for separating process and control media ✔️ Leakage indicator ✔️ Surface finish available: medium-wetted Ra ≤ 0,38 µm and externally Ra ≤ 0,76 µm (electropolished) More information on our pressure reducing valve can be found on our website: https://lnkd.in/gxdtbmUb #Mankenberg #Valves #Industrialvalves #Pharmaceuticalindustry

During tank emptying, in closed piping systems, or within thermal processes: an uncontrolled vacuum can damage equipment and plants, disrupt processes, and create safety risks. This is exactly where 𝘃𝗮𝗰𝘂𝘂𝗺 𝗯𝗿𝗲𝗮𝗸𝗲𝗿𝘀 and 𝘃𝗮𝗰𝘂𝘂𝗺 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝘃𝗮𝗹𝘃𝗲𝘀 come into play. With our knowledge hub on our website, we share practical expertise: 𝗩𝗮𝗰𝘂𝘂𝗺 𝗯𝗿𝗲𝗮𝗸𝗲𝗿𝘀 Vacuum breakers protect vessels and pipelines against vacuum. A vacuum can build up when a system is being drained, when it cools down or when a pump fails. Vacuum control valves are pressure reducing or overflow valves which control pressures below 1 bara. Operation: Vacuum breakers are normally closed. If the pressure inside a tank or vessel drops below atmospheric pressure by more than the set differential pressure, the valve opens causing the system to be vented until the set pressure difference has been established again. Vacuum breakers remain closed when the pressure rises above atmospheric, therefore they do not offer protection against excessive pressure. 𝗩𝗮𝗰𝘂𝘂𝗺 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝘃𝗮𝗹𝘃𝗲𝘀 Vacuum control valves regulate the negative pressure in pipes, vessels, and similar systems. Field of application and function: 👉 Based on pressure reducing valves (DM): maintaining a vacuum The vacuum to be maintained acts on the control diaphragm via the sense line connection in the spring bonnet and is in balance with the spring force. The valve is open when there is no pressure and closes as soon as the vacuum falls below the set value. The valve opens when the differential pressure to the atmosphere decreases. Example: Supply pressure: 8 bar Vacuum to be maintained: -0.7 bar (0.3 bara) Medium: Nitrogen The control valve is open at -0.6 bar (0.4 bara) and closed at -0.8 bar (0.2 bara) 👉 Based on back pressure regulators (UV): limiting a vacuum The vacuum to be limited acts on the control diaphragm via the sense line connection in the spring bonnet and is in balance with the spring force. The valve is closed when there is no pressure and opens as soon as the set vacuum is exceeded. The valve closes when the differential pressure to the atmosphere decreases. 🔎 For more knowledge and process reliability, visit our website: https://lnkd.in/dRM2jHzq #Mankenberg #Valves #IndustrialValves
