    ]]>         Hydraulic Pressure Testing for Valve Sizes DN15 to DN65 https://majorvalves.co.za/shop/hydraulic-pressure-testing-for-valve-sizes-dn15-to-dn65/ Mon, 14 Sep 2026 06:55:11 +0000 https://majorvalves.co.za/?post_type=product&p=2661 Ensure pressure boundary integrity and leak-free performance with our precision hydraulic pressure testing for DN15 to DN65 valves. Built to satisfy demanding industrial standards including API 598 and ISO. Our testing solutions deliver rigorous hydro-testing for small-to-medium bore ball, globe, gate, check, and butterfly valves.

    Key Capabilities & Technical Specifications

    • Nominal Sizes: DN15 to DN65
    • Standard Compliance: Shell hydrostatic testing & high-pressure fluid seat closure testing.
    • Test Media: Demineralized water with corrosion inhibitors, filtered to ISO cleanliness specifications.
    • Fixturing & Clamping: Hydraulic quick-clamping tables with proportional clamping force to prevent valve body distortion during high-pressure cycles.
    • Instrumentation: Calibrated digital pressure transducers and automated data logging for traceable pressure-hold verification and zero-leakage certification.
    Ideal for valve manufacturers, overhaul workshops, and quality assurance facilities requiring rapid cycle times, high repeatability, and strict adherence to international safety standard compliance.
