The MHV-HB600/24-S integrates hydraulic clamping, electrical control, and high/low pressure water supply into a single test station. The horizontal layout simplifies loading and positioning of large flange valves, while the claw clamp mechanism presses and fixes the valve at the flange end face to maintain stable sealing conditions during testing.
To improve operating convenience for large valves, the worktable design supports 90° rotation and left–right movement, making it easier to access sealing interfaces and adapt to different valve face-to-face lengths. The overall structure is engineered to meet workshop hydrostatic test and sealing test procedures for DN250–DN600 valves.

Clamping and Worktable Design Logic
To improve repeatability and handling efficiency for large valves, the MHV-HB600/24-S applies a combined mechanical structure:
- Claw clamp pressing on flange end face: ensures stable positioning during pressure buildup and reduces movement risk under test pressure.
- High-capacity hydraulic clamping system (200 tons): designed for large-size valves and higher holding requirements.
- 90° rotatable worktable: improves accessibility for sealing inspection, tool positioning, and valve handling.
- Wide mechanical adaptability: supports valve length 610–1067 mm, flange OD 460–840 mm, and flange thickness 26–70 mm, covering typical DN250–DN600 flange valve formats.
