GE Masoneilan

GE Partner & MARC Authorised Repair Center


Quality products, combined with expert service have made GE an industry innovator for more than a century. As an accredited GE Masoneilan Authorized Repair Center (MARC) you can rely on Multiplex for convenience and responsiveness. We are able to offer GE approved spares, repairs and after market support.


Repair is an integral part of the service we offer. Whether you have GE’s Masoneilan valve products or products from another manufacturer, you can count on Multiplex to complete your repair quickly while maintaining quality standards. In addition to having the technical expertise and product knowledge to do the job right, GE’s MARC operations are outfitted with the right tooling. At your site or at our facility in Chesterfield, our MARC technicians have the resources to inspect, diagnose, repair and recalibrate your equipment. You can be confident that equipment repaired through Multiplex can be returned to service in “like new” condition. No matter how complex or simple the job, and regardless of the original equipment manufacturer (OEM),  we're ready to respond to your specific needs.

Performance through People

The high-quality service that you have come to expect from GE’s MARCs is the result of an experienced, well-trained, and dedicated staff. Each MARC technician receives mandatory training on valves, diagnostics, and digital equipment, providing you with highly skilled individuals capable of handling even the most complex job requirements.

Original Spare Parts

Replacement parts are critical to your operations. Insist on quality original equipment (OEM) parts available exclusively through your MARC dealer. MARCs maintain an inventory of genuine Masoneilan parts, and can draw from the entire MARC network as well as GE’s Masoneilan Aftermarket Center to supply the original equipment parts that were made for your application.


We understand that repairs are often urgent, and our repair centers are equipped to support your needs 24 hours a day, 365 days a year. With well-trained, experienced technicians you can rely on us to respond to your needs quickly and efficiently while helping to reduce disruptions and maintenance costs.

Value Added Service

In addition to covering a full range of repair and support services, MARCs also offer a portfolio of advanced services, including upgrading to digital devices; commissioning valves upon installation; managing assets with ValvKeep*, GE's proprietary asset management tool; and performing advanced diagnostics and valve health checks using GE’s Valscope*-Pro diagnostic tool. And to better plan your maintenance while improving efficiency and uptime, take advantage of a unique service from GE’s MARCs -- diagnosing control valves during normal operations. Using GE’s ValVue* Online Valve Diagnostics (OVD), MARCs can schedule regular visits to monitor the health of your most critical assets and provide recommendations for corrective actions.

Delivering Operational Improvements

As a GE Masoneilan Authorized Repair Center we can help ensure that your control equipment assets are functioning properly. Our factory-trained technicians will work to help ensure that the valve, actuator, positioner and control valve assembly accessory components work effectively together.
