Industrial Valve Replacement or Repair: Which Should You Choose? Request a Quote Contact Us
Thousands of small-diameter ball, check, globe, and gate valves are installed in industrial plants to facilitate a variety of power, process, mixing, and refining applications. They are critical for ensuring reliable control over the temperature, velocity, pressure, and flow of a wide range of media. When one of these valves fails, many organizations opt for valve replacement rather than repair. The choice between industrial valve repair and industrial valve replacement depends on a number of considerations.
Below are some of the factors to take into account when determining whether to repair or replace a valve.
Factors To Consider When Repairing or Replacing Valves
When considering whether you should repair or replace your industrial valve, the experts at Conval recommend considering the following factors:
- Top Entry Design
Two-piece and end entry welded-in ball valves are not in-line repairable; while top entry ball valves are inherently in-line renewable. Speedy removal and replacement of valve trim is achieved via valve maintenance that is performed in-situ through top entry access to all the functional components within the valve. Similarly, though globe valves typically have top-entry access, not all are designed for quick and easy renewal in line.
- Downtime Reduction
Time is money, and one valve failure can shut down an entire process line. To maintain process function, all systems are required to either have reliable components, backups/redundancies or possess the capability for speedy maintenance processes. Process uptime is invariably vital, and the long term cost of poor quality should be factored into the initial valve selection.
- Ease of Repair
Ease of repair starts with a valve design that facilitates simple disassembly. The availability of replacement parts, trained technicians and service tools are also critical for ease of repair. In addition, there must be ready access to the valve to effect repairs.
- Ease of Replacement
There are a number of considerations that go into the replacement decision. Availability of the replacement valve, valve connection (flanged versus welded), access to the valve for cutting and removing it, scaffolding, hot permitting, post weld heat treating (PWHT)
- Relative Cost – Repair vs. Replace
Generally speaking and contingent on valve size, material and pressure class, the cost advantage lies in repair over replacement. Downtime, committed man-hours, valve cost versus replacement parts.
