Testing & Quality Assurance

At Valve Check, every product we manufacture undergoes rigorous in-house testing to ensure performance, reliability, and compliance.

  • 100% Crack Pressure Testing
    Every adjustable valve is tested for crack pressure accuracy. Our process includes both reverse flow and leak testing, performed with a ±5% accuracy tolerance to guarantee consistent performance in the field.
  • Custom-Built Testing Equipment
    Our testing operations use a combination of precision Alicat digital pressure and flow regulators, along with custom-built rigs designed specifically for our products. This ensures accurate, repeatable, and application-specific results.
  • Cleanliness Standards
    All testing is conducted in-house under strict cleanliness controls. When required, we can also outsource passivated cleanliness services to meet higher-grade applications.
  • Material Assurance
    We offer 100% lead-free valve options, giving customers confidence that our products meet both performance and safety requirements.

Our testing process isn’t just a box to check — it’s a commitment to delivering valves that perform reliably from day one.
