Multiport Selector Valve Skids (MSV)

Multiport Selector Valve Skids (MSV)

With the Multiport Selector Valve skids, it is possible to receive the flow from five or more oil or gas wells. It consists in one steel body with five or more incoming flow lines or inlet-ports and two outlet-ports.

One of the outlets (the bigger) collects and transfers oil or gas to production line and the other one (the smaller) collects and transfers fluid to test line coming from selected wells.

The standard valve sizes are:

valve sizes 2x4

2”x 4”

  • 2" - Inlets
  • 2" - Test Outlet
  • 4" - Production Outlet
valve sizes 3x6

3”x 6”

  • 3" - Inlets
  • 3" - Test Outlet
  • 6" - Production Outlet
valve sizes 4x8

4”x 8”

  • 4" - Inlets
  • 4" - Test Outlet
  • 8" - Production Outlet
valve sizes 4x10

4”x 10”

  • 4" - Inlets
  • 4" - Test Outlet
  • 10" - Production Outlet
valve sizes 6x16

6”x 16”

  • 6" - Inlets
  • 6" - Test Outlet
  • 16" - Production Outlet

Main Advantages of Multiport Selector Valve Skid

The heart of the skid production pad is the Multiport Selector Valve, as described above, fitted with an electrical actuator. Each line connected with the inlet and outlet-ports is complete with his block ball valve, check valve, relief and drain valves, pressure and temperature transmitters. Therefore, when the skid is received in the field, it is ready for connection, commissioning and subsequent operation. No painting, welding, or field testing is needed.

  • Modular, Compact and self-contained.
  • Low maintenance.
  • Combined solution: Multiphase Meter – Multiport Selector Valve.
  • The Skid has a small ecological impact and because of its reduced footprint, it is ideal for offshore applications.
  • No concrete foundation required.
  • It can be delivered, installed, commissioned and start up within a few days.
  • Multiphase meter test on-line (in-situ). The systems are completely tested in the factory (Dye penetrant inspection, pressure test, RX inspection, functional tests).
  • H2S service parts designed for hydrogen sulfide corrosion resistance.
  • The skid can be connected in cluster (several skid connections for 14, 21, 28 or more wells).


The Multiport Selector Valve Skid show on 1st page and some pics below is mounted for Iraq. This is also a good prospect for other markets. In Saudi this is still not active as Aramco focuses on individual well healthiness check.
