MHV-HD1000/15-S 수평형 최고 압력 밸브 테스트 벤치

제품 소개

The MHV-HD1000/15-S Horizontal Top-Press Valve Test Bench is a heavy-duty valve pressure testing machine designed for pressure testing of large valves in the DN250–DN1000 range. This bench adopts a horizontal top-press structure and is used for valve shell strength testing, high-pressure sealing testing, and low-pressure gas tightness testing according to the specified test procedure.

It is applicable for pressure testing of straight-through flanged, welded, or threaded valves, including gate valves, ball valves, check valves, and related valve types.

제품 설명

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.
