Flow Control Solutions
A control valve varies the rate of flow passing through itself. The valve stem moves, altering the size of the passage and this increases decreases or holds steady the flow. The control valve opening is altered whenever the process parameter being controlled does not equal the value it is meant to be (the set point).
Flow Control Valves react to an increase in the parameters they control by throttling closed. This is a “progressive” process an increase in demand results in the valve reducing the flow progressively. The more the valve closes, the more the downstream pressure is reduced. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. There are different types of flow control valves available in the market. Gate valves, globe valves, pinch valves, diaphragm valves, and check valves are some major categories. We can discuss more details related to these types in this section.

6. MULTIPORT SELECTOR VALVE (MSV)
The Multiport Selector Valve (MSV) is an engineering device that provides a cost-effective and compact means to improve production management and well optimization. The MSV allows the diversion of fluids from a single flow line to a test outlet or a sampling device. A single MSV can manifold as many as seven flow lines through it simultaneously. While one inlet is isolated, the flow from the other six is combined into a separate group outlet.
This unique flow selector can be used in a variety of oil and gas or process applications either as a standalone device or with a multiphase meter. The MSV can also be used for water injection for Enhanced Oil Recovery (EOR) projects. It provides control simplicity in an environment where size, weight, and reliability are all key factors. The Multiport Selector VALVE reduces the costs of installation, operation, and maintenance of the well-test system throughout its life cycle.
One single MSV can replace an entire arrangement of 2 or 3-way valves for a 3-way well. The selecting system, functioning as a compact manifold, provides an easy and safe way to select the wells you wish to connect to the Multiphase meter or the test Separator. It has eight (8) inlets to connect the production wells, and two (2) outlets: a standard one for production and a selectable one for test purposes. This setup allows one to connect up to seven (7) wells, since one of the inlets remains free for field resetting of the seal, and to avoid having a well being connected for test purposes all the time. In this way, using the manual or the intelligent positioning system of the rotor, you can direct each of the wells individually to the testing outlet, while the remaining six continue their production through the group outlet. Multiport Selector Valves are designed to deliver economic test automation accompanied by straightforward simple installation and control.
FEATURES:
- The compact design of the MSV reduces installation costs and the one basic moving part reduces maintenance. The self-cleaning feature prevents the build-up of scale, paraffin, and other deposits.
- Also the MSV provides fewer sealing surfaces allowing less opportunity for leakage.
- The MSV is offered as either a manual or an automated operation and the automation can be added at any time.
- With 8 inlet ports, the RSV can manifold up to 8 flow lines at one time. It is a compact manifold with reduced size and weight.
- The MSV has a field adjustable seal, with stainless steel scraper for extended service life
- The MSV is especially suited for use with Multiphase Meters.
- Available with two-wire communication for remote control and status indication
- Constructed to applicable parts of API 599.
- Reduces the number of isolation valves in production/test manifolds.
- Operating temperature range:-20° F to +392° F (-29° C to +200° C)
- Available with a multitude of trims and surface treatments for all operating environments.

It combines an exclusive solid-state motor starter with control software to provide precise positioning of the Multiport Flow Selector within +/- 1.5 degrees of the selected port, retaining that position even in the event of a power loss. The Actuator provides a configurable port selection from 2 to 10 ports, and an LCD display indicates the port number and when moving between ports, the port numbers on either side.
Control is via local selectors, a remote-mounted control station, or a MODBUS network. Local operation and the remote station control will index the ports up or down. MODBUS control allows the desired port to be selected; the control intelligently chooses the fastest path to the desired port position when in bi-directional mode. Each time the actuator passes through port I the port positions will be re-synchronized to ensure that there is no incremental positioning error.
The Actuator allows the user to select any port as a home port or skip any unused ports. This actuator allows for field torque adjustment while protecting the Multiport Flow Selector from excessive torque.
MSV Actuator is designed to operate in harsh and hazardous environments. A manual override is provided to operate the MSV upon loss of power. The actuator is capable of working with a wide range of voltages – three-phase, single-phase, and DC.
