The MHV-HD1000/15-S is an integrated valve test bench combining the hydraulic system, electrical control system, high/low pressure water pump pressure supply device, oil/water/gas pressure instrumentation system, control valve system, clamping worktable system, and medium circulation storage tank.
The bench uses a horizontal top-press cylinder to directly apply axial pressing force on the tested valve end face. The sealing between the valve and blind plate adopts an end-face O-ring sealing method. During testing, pressure is supplied through the high/low pressure water system, and the system supports 4–7 bar low-pressure gas tightness test conditions (air or nitrogen) as specified.
