Quality & HSE

At LOZOSE, quality is our number one concern and our stringent requirements are the direct cause of our control valves' compliance with high performance, high safety and high standards. We know that in an industry with high precision and critical service life, our customers use our products as the first requirement for valve quality screening.

Our complete quality monitoring program allows our manufacturing process to be tracked in real time, from selection to blank to material to final production inspection. Key steps in our quality monitoring include:
  • Rigorous test requirements: Each valve is rigorously tested to meet or exceed industry standards.
  • Carefully reviewed materials: We use only the highest performance materials, which we have carefully selected for long life, corrosion resistance, and suitability for special conditions. Our suppliers are rigorously audited so that the materials they provide meet our strict requirements.
  • Proven manufacturing technology: Using the most advanced technology and manufacturing processes, we produce valves with superior precision and quality.
