Descrizione del prodotto

MDV-2000/3.75-S integrates the hydraulic system, electrical control system, high/low-pressure water pump pressure supply device, oil pressure / water pressure / gas pressure instrumentation system, control valve system, clamping worktable system, and medium circulation storage tank.

The bench uses a claw-type clamping structure to clamp the valve flange end face. The clamping force is adjustable. The sealing between the butterfly valve and blind plate uses an end-face O-ring sealing method, and the leakage position can be observed.
