Multiport selector valve (MSV) is a cost-effective, efficient and compact engineering device, which can improve production management and well optimization. MSV allows fluid to be transferred from a single pipeline to a test outlet or sampling device. A single MSV can pass through up to seven pipelines simultaneously. When one inlet is isolated, fluids from the other six inlets are combined into a single outlet.

This unique fluid selector valve can be used either as a stand-alone device or in combination with multiphase flow meters in various oil, gas or process applications. MSV can also be used for water injection to enhanced oil recovery (EOR). It can be used to simplify control in environments where size, weight and reliability are key factors. MSV reduces the installation, operation, and maintenance costs throughout the life cycle of a well testing system.

A single MSV can be used as a replacement for a complete 2-way or 3-way valve in the test well selection system, acting as a compact manifold and providing a simple and safe way to select the multiphase flow you wish to connect to or test the well of the separator.

However, most of the common MSV at present adopt a soft sealing structure. Although the structure of the MSV is simple, because of its use of soft material as a sealing pair, it is not resistant to wear and has a very short life. The sealing surface of the MSV produced by Jiangsu Ludy can be overlaid and spray welded, and the hardness can reach HRC60 degree or higher. The sealing surface is scratch-resistant, wear-resistant, erosion-resistant and corrosion-resistant. It is easy to operate and does not require to change the sealing material, which is suitable for various oilfield environments.
