LIQUEFIED NATURAL GAS
LNG is exactly what it says: the liquid form of natural gas. The process of liquefying is performed to reduce the volume for purposes of transporting the fuel: LNG reduces volume by 600 times, making it much more economical to transport.
VALVES are a critical component at each stage of the liquefication process. Valve performance and reliability are important to the whole process.
Thanks to design and state of the art manufacturing technology, Maverick Valves offer 100% compliance even with the highest tightness or temperature requirements. With this design, we offer you the perfect solution for demanding LNG applications.
When it comes to temperatures below -162° C the industry talks about cryogenic applications. We find these temperatures in different applications like air separation plants, chemical plants or LNG plants.
With our various types of Valves, engineered, manufactured and tested in our ultra-modern plant in Tilburg, The Netherlands, we can handle cryogenic applications. Thanks to our design and construction our valve acts with a totally round seat and sealing geometry. This construction allows for handling these extreme temperatures. Even if the material is shrinking and expanding due to extreme temperatures, our valves are keeping their promises of 100% tightness.
The cooperation with primary quality European suppliers of gaskets and seals allow to keep FE levels to the highest standards, with a wide range of certification for all gasketing material (SHELL MESC 85-103, 85+200, 85-203, 85-204, API 622, LI TP PVA 001, ISO 15848): For cryogenic service the material selection is ranging basically between austenitic stainless steel up to CRAs. Refer to our catalogue for a wide material listing and related allowable wotking pressure. The fire safe design of the valve is achieved with the use of graphite rings insertions of the sensible leak paths.
For all the valves where the body cavity can be left isolated and sealed in closed position, as for instance happens in gate valves, Maverick Valves recommends to apply a cavity pressure relief system- This can be achieved through an external routing pipe supplied with a check valve and eventually with block valves. The piping can be a SS316 compression fitting assembly or an ASME socket weld piping, as per customer specification. The easiest solution is a drilled relief hole connecting the body cavity with the upstream line, directly drilled on the disc. The relief hole as a consequence will inhibit the bi-directionality of the valve, so far other arrangements can be provided.
