Multiport Selector Valve (MSV)

This unique flow selector can be used in a variety of oil and gas or process applicationseither as a standalone device or with a multiphase meter. The MSV can alsobe used for water injection for Enhanced Oil Recovery (EOR) projects. It providescontrol simplicity in an environment where size, weight and reliability are all keyfactors. The EXACTA Multiport Selector VALVE reduces the costs of installation, operation andmaintenance of the well test system throughout its life cycle.

One single  MSV can be used as replacement of an entire arrangement of 2 or 3 way valves for a  test well Selecting system, functioning as a compact manifold providing an easy and safe way to select the wells you wish to connect to the Multiphase meter or to 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 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.

EXACTA Multiport Selector Valves are designed to deliver economic test automation accompanied by straight forward simple installation and control.

FEATURES

—         The compact design of the EXACTA MSV reduces installation costs and the one basic moving part reduces maintenance. The self-cleaning feature prevents build-up of scale, paraffin and other deposits.

—         Also the EXACTA MSV provides fewer sealing surfaces allowing less opportunity for leakage.

—         The EXACTA 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. Its 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 EXACTA MSV is especially suited for use with Multhipase Meters.

·         Available with two-wire communication for remote control and status indication

·         Constructed to applicable parts of API 599.

·         Reduces 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.

CONVENTIONAL TEST MANIFOL vs. MULTIPORT SELECTOR VALVE ARRANGE

The Multiport Selector Valve Arrange consists ofgroup of pipes and secondary valves and telemeters and one MSV.

The operational heart of this equipment is the MSV, which has an Intelligent Actuator. All the connections to the 7 inlets of the Multiport Valve, as well as for the 2 outlets (Production and test), are mounted on an oilfield transporting skid. These inlets and outlets are supplied with the corresponding, insolating valves, check valves, pressure and temperature transmitter so therefore, when the assembly is received in the field, it is ready for connection and subsequent operation;  no needs of painting, welding, or field testing on the site!!!

Some noticeable features of  this configuration:

·         Modular, Compact and self-contained.

·         Low maintenance.

·         No concrete foundations required.

·         Moving, installing, commissioning and start up in 15 days.

·         Multiphase meter test  on-line ( in-situ.).

Actuator The Actuator consists of: A control system. Electric motor. (: 24VDC, 120-480VAC, 50-60Hz, Class 1, Div 2. Groups C y D ) Human-machine interface. Network control Modbus Hazardous atmosphere enclosure, Continuous 360° driver Gear Box Manual Override It combines an exclusive solid state motor starter with control software to provide precise positioning of the Multiport Flow Selector within +/- 1.5 degree of the selected port, retaining that position even in the event of a power loss. The Actuator provides configurable port selection from 2 to 10 ports; and a LCD display indicates port number and when moving between ports, the port numbers on either side. Control is via local selectors, 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 choosing the fastest path to the desired port position when in bi-directional mode. Each time the actuator passes through port 1 the port positions will be re-synchronized to ensure that there is no incremental positioning error.  The Actuator allows user to select any port as home port or skip any unused ports.  This actuator allows for field torque adjustment while protecting the Multiport Flow Selector from excessive torque. EXACTA MSV Actuator is designed to operating 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.
