Marvac – 77A Tank Blanketing Valve
MARVAC is regarded as the world leader in the design and manufacture of tank protection, and access valves to limit the pressure and vacuum created by changes in atmospheric pressure. As pressure rises or falls, MARVAC pressure relief valves allow the tank to breathe, preventing damage and spillage to ensure the safety of personnel and the surrounding environment.
MARVAC pressure relief valves, vacuum relief valves and combined pressure and vacuum relief valves can be weight, spring or pilot operated. All MARVAC products are UDT and GOST-R approved and compliant with the European ATEX and PED directives where applicable.
MARVAC‘s team of engineers have unrivalled experience in dealing with tank storage applications, enabling them to assess each customer’s individual specifications to provide the optimum safety solution. MARVAC products typically operate within a range of -800 mbarg to 3.5 barg and -196°C to 250°C, but extended parameters are available on request and after consultation.
Tank blanketing valves are dedicated to providing inert or rich blanketing of storage tanks to limit evaporation and reduce harmful emissions.
