Valve Maintenance, Repair and Testing

Workshop and in-situ support for the overhaul, testing, certification, flushing, lubrication, and emergency servicing of industrial valves and actuators.

Reliable Valve Support

Valves play a critical role in isolation, pressure control, process performance, and the safe operation of industrial systems. When a valve requires planned maintenance, testing, repair, or urgent attention, the work must be carried out with the right technical resources and a clear understanding of the operating environment.

NSA coordinates workshop and in-situ support for safety valves, gate valves, control valves, and actuators. Through one local point of contact, clients can access the experienced personnel, specialized tooling, and testing resources required to address individual valves or broader maintenance programs.

Workshop and In-Situ Service

Valve requirements vary according to the equipment, service conditions, location, applicable standards, and available maintenance window. NSA works with clients to define the scope before coordinating the appropriate service approach, whether the work is completed in a workshop, at the operating site, or as part of an offshore campaign.

Workshop support can be coordinated for valve overhaul, testing, and certification requirements. Where removal is impractical or an in-service solution is more appropriate, available field capabilities may include Electronic Valve Testing (EVT), flushing, lubrication, and emergency sealant injection. NSA can also coordinate the personnel, tooling, and test equipment needed for planned shutdowns, valve campaigns, and PSV recertification programs.

Every valve requirement carries its own operating, safety, and scheduling considerations. NSA coordinates experienced technicians, specialized tooling, testing capabilities, and service resources around the valve, location, and demands of the operation.
Valve Service Capabilities

NSA provides access to coordinated valve maintenance, repair, testing, and certification support for a range of industrial and offshore requirements. Each scope is reviewed individually so the work approach, documentation, personnel, tooling, and test equipment can be matched to the valve and its operating conditions.

  • Safety and pressure safety valves — Overhaul, testing, and certification or recertification support for applicable safety and PSV equipment.
  • Gate valves — Workshop or field support for maintenance, overhaul, servicing, and testing requirements.
  • Control valves and actuators — Coordinated technical support for control-valve assemblies and their actuation systems.
  • Electronic Valve Testing (EVT) — In-situ electronic testing for applicable valves when field verification is suited to the requirement.
  • In-situ valve servicing — Flushing, lubrication, and emergency sealant injection for applicable field-service requirements.
Frequently Asked Questions
What types of valves does NSA support?

NSA coordinates service for safety valves, pressure safety valves, gate valves, control valves, and actuators. The exact service approach depends on the valve type, size, pressure class, operating conditions, location, and required standard.

Are valve services available in a workshop and in situ?

Yes. Depending on the requirement, NSA can coordinate workshop-based overhaul and testing or in-situ services at the operating location. Site access, tooling, testing requirements, personnel availability, and the condition of the valve are reviewed before the work approach is confirmed.

Can NSA support offshore valve campaigns and shutdowns?

Yes. NSA can coordinate technicians, tooling, test equipment, and service planning for offshore valve campaigns, scheduled shutdowns, maintenance programs, and PSV recertification scopes. Availability and logistics are confirmed for each project.

Does NSA provide PSV recertification support?

NSA can coordinate the inspection, overhaul, testing, and recertification of applicable pressure safety valves through appropriately qualified personnel and equipped facilities. The governing standard, documentation requirements, certification scope, and schedule are confirmed before work begins.
