Valve Services

The Westinghouse Solution

As a full-service integrated valve and actuator maintenance company, Westinghouse performs preventative and predictive maintenance services and diagnostic testing on valves and motors of all manufacturing types. We leverage our industry-recognized training programs, integrated project management approach and our First-Time Quality process to ensure that our customers’ most complex valve projects are completed on time and on schedule.

Customer Benefits

Westinghouse differentiates itself from our competition with a leadership team comprised of utility line managers with extensive maintenance and operations experience in the commercial nuclear industry that undergo a rigorous leadership training process. This direct “handson” utility experience is essential to the planning, execution, and on time delivery of complex projects.

We have an INPO modeled performance-based technical training and qualification program with EPRI AP-3 compliance certification. This approach improves quality while reducing cost to the utility by mitigating onsite qualification activities. Duty-area cross-qualification exists to enable technicians to support both actuator as well as in-body valve repairs; thereby reducing overall resource requirements and outage costs.

Westinghouse provides an integrated planning and project management system to safely execute any valve project on schedule and budget. Our integrated process includes in-depth pre-planning, comprehensive project reviews, risk assessments and contingency development.

We possess one of the industry’s top recruiting organizations comprised of a dedicated team of full-time recruiters staffing more than 8,000 professional and craft positions during peak outage seasons.
