Valve Material Specifications

Reliable valve performance starts with choosing the right material. At TOMOE VALVE INC, we focus on two critical aspects:

  • Strength Under Pressure For demanding, high‑pressure systems, we use forged steel and advanced alloys to ensure resilience. In lighter duty applications, cast iron remains a practical choice.

  • Defense Against Corrosion Valves often face aggressive fluids and harsh operating conditions. Internal corrosion from process media is a greater risk than external rust, so our material selection considers fluid chemistry, temperature, and environment to maximize service life.
