introduction du produit

The MHV-HB300/37.5-S Horizontal Claw Clamp Valve Test Bench is a dedicated valve pressure testing machine designed for hydrostatic strength and sealing performance tests on industrial valves with flange connections. With a horizontal “claw clamp” holding structure and integrated hydraulic/electrical control, this bench supports stable hydrostatic test workflows for DN80–DN300 valves in manufacturing and inspection environments.

It is engineered for practical workshop testing where fast clamping, secure sealing, and repeatable pressure verification are required—making it a reliable choice for valve manufacturers and inspection stations performing routine valve test and quality control.

Description du produit

This valve test bench integrates hydraulic clamping, electrical control, and high/low pressure test water supply into a single station. The horizontal layout supports convenient loading and positioning of DN80–DN300 flange valves.

The bench adopts a claw clamp structure to press and fix the valve at the flange end face. The clamping mechanism drives the fixture movement to achieve accurate positioning without introducing external force that could affect sealing evaluation. The right-side worktable supports 90° rotation, improving accessibility for sealing and tightness verification operations. The worktable can also move left and right to adapt to different valve face-to-face lengths.

Clamping & Worktable Design Logic

  • To improve repeatability and operational efficiency, the MHV-HB300/37.5-S uses a combined mechanical structure:
  • Claw clamp pressing on flange end face: reduces the influence of external forces on sealing evaluation and improves stability during high-pressure tests.
  • Left–right synchronized fixture movement: supports precise positioning and reduces setup time across different valve sizes.
  • 90° rotatable right-side worktable: enhances accessibility for sealing checks and operational handling.
  • Wide mechanical compatibility: supports valve length 203–750 mm, flange OD 190–520 mm, and flange thickness 20–83 mm, making it suitable for a broad range of DN80–DN300 flange valve formats.
