Ladish In-House Manufacturing & Quality Control

Time tested design meets the latest technology for technical excellence.

Solidworks 3D Rendering

Controlled quality is more than just a corporate Ladish slogan. It’s a daily activity that drives our processes to produce quality, long lasting valves. The Ladish trademark is a representation of the highest quality standards, fine engineering skills, craftsmanship, modern manufacturing and testing equipment that provides assurance of manufacturing responsibility and integrity.

Ladish Valves uses the latest technical tools available to:

  • Update existing proven designs
  • Extend product lines through detailed step-wise design process
  • Continually create new product lines
  • Work with vendors to insure quality manufacturing standards
  • Facilitate new pattern design with foundry vendors
  • Use simulation models to gain valuable insight early in the design process
  • Assist customers and identify root causes in the field
  • Perform Finite Element Analysis (FEA) to insure soundness of design
  • Increase product quality while reducing the costs of live prototyping and testing
  • Connect engineering to the machine shop via Solidworks drawing files
  • Actively participate on standards committees
  • Calculation of pressure-temperature ratings for unlisted materials
  • Design and developing in-house testing to ensure compliance to the Ladish standards

Through an extensive, controlled program of research & development for improved methods, processes, materials & designs, we assure that Ladish Valves will continue To Mark Progress.

Our proprietary quality database:

  • Makes every valve fully traceable to every heat and lot number for ALL inspections & fabrication points from receipt of raw material to shipment of final product
  • Is fully integrated throughout local servers for efficient distribution of records, procedures and documents. Documented corrections to any non-conformance with re-qualification testing recorded. Calibration control of all measuring & monitoring devices.
  • Documented corrections to any non-conformance with re-qualification testing recorded.
  • Calibration control of all measuring & monitoring devices.
