Valve Packing Improvement Program
The benefits of utilizing Graphite packing arrangements has been recognized in the power generation industry over the past two decades. Elimination of asbestos-based products and improved packing performance have been the major reasons for converting to flexible graphite.

However, with today's concerns about valve reliability, configuration control, and improved maintenance training, a complete valve packing program offers substantial benefits. These benefits include:

  • Improved packing performance
  • Insure plant reliability
  • Increased MOV and AOV reliability
  • Elimination of asbestos
  • Improved maintenance records
  • Reduced inventory

Experienced Technical Support
NGP provides the technical assistance necessary to implement a graphite packing program. This technical support is flexible and can be customized to individual plant requirements.

Services ranging from continuous on-site technical support to computer software packages allow stations to utilize NGP's technical service to assist in implementing a successful valve packing program.

Proven Quality
The proof is in the performance, and NGP's graphite packing arrangements have outperformed competitors in both laboratory and actual field testing.

A complete quality assurance program and state-of-the-art manufacturing processes insure the highest level of excellence.

Research and Development
A continuous research and development program is underway at NGP to improve valve packing materials and arrangements. Recent testing done at Chalk River Nuclear Laboratories with NGP's graphite packing configurations have shown significant improvements over previous results from EPRI funded testing.

These improvements include:

  • Increased packing life
  • Reduced packing friction
  • Zero leakage
  • Reduced initial and in-service consolidation

Unparalleled Service
Having high quality materials and experienced technical support would not be worth much if it could not be placed on-site in a timely manner. Because NGP specializes in the power generation industry, we understand that schedules sometimes change or material may be needed to bring a unit on-line. By utilizing NGP, you'll receive next-day delivery on emergency orders. In addition, a technical representative can either provide on-site assistance or phone consultation to assure proper installation.
