Dynamic Performance Verification: We simulate the valve’s operating environment to verify dynamic response and stability, confirming its ability to precisely handle rapid changes in flow and pressure demanded by your application.
Leakage and Pressure Integrity: We perform high-pressure tests to confirm absolute internal and external pressure integrity and measure leakage rates, guaranteeing optimal efficiency and component longevity.
Certification and Seal: Upon passing all required tests, Brant Hydraulics certifies the valve, and it receives our Quality Assurance Seal before it leaves our facility.
