Did you know
- Motherwell Tank Protection's heritage in manufacturing dates back to 1859 with the establishment of Bold Iron Works, which later, as Neill-Varec, produced tank level measuring devices and pressure relief valves. The company became a subsidiary of Motherwell Tank Holdings in 2003.
- The Motherwell Tank Protection Pressure-Vacuum Relief Valves (PVRV) are part of a broader range of tank protection equipment, which also includes pressure-only relief valves (PRV) like the CNC381 & CNC384, and vacuum-only relief valves (VRV) such as the CNC382 & CNC387. The PVRV models, specifically the CNC380, CNC383, CNC385, and CNC386, offer combined pressure and vacuum relief, distinguishing them from the single-function valves.
- These PV valves are designed to protect low-pressure storage tanks from damage due to changes in internal pressure and vacuum, while also minimizing the emission of vapors. They are ATEX-approved and offer a range of customizable options for size, material, and pressure settings.
