GANTRY VALVE TESTER
A variation from the standard CALDER USV product line, the custom USVG-24-300T valve tester was engineered to optimize loading, unloading, and hydrostatic valve testing of large control valves.
Capable of clamping and testing 4 to 24 inch (101.6 to 609.6 mm) valves with a maximum test pressure of 9,700 psi (668.8 bar), this massive machine uses an upper gantry assembly with heavy-duty rollers and hydraulic cylinders that enables the upper section to move forward and backward for valve loading and unloading onto the stationary platform seal plate. This versatility was ideal for the customer’s facility as they used an overhead horizontal crane to position their valves flange-down for testing.
