introduction du produit

The MDV-600/15-2S Hydraulic Butterfly Valve Test Bench (Sleeve Type) is a dedicated test bench for pressure testing of straight-through flanged butterfly valves and wafer-type butterfly valves. It provides two working ranges on one set of equipment: DN50–DN250 and DN250–DN600. The bench is used to complete the specified test items, including 1.5×PN hydrostatic shell test, 1.1×PN high-pressure hydrostatic sealing test, and 4–7 bar low-pressure gas tightness test (air or nitrogen).

Description du produit

The MDV-600/15-2S sleeve-type hydraulic butterfly valve test bench integrates 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 into one unit. The test process and results meet relevant requirements.

The test bench uses a claw-type clamping structure to directly clamp the butterfly valve at the flange end face. The clamping mechanism is driven by hydraulic cylinders for operation.

Product Features and Functions

  • Test valve type: straight-through flanged butterfly valve or wafer-type butterfly valve
  • Installation method: claw-type pressing and clamping at the end face, stable clamping, minimal external influence
  • Sealing method between butterfly valve and blind plate: end-face O-ring sealing, easy to observe leakage position
  • Test medium: water; 4–7 bar low-pressure gas (air or nitrogen) tightness test
  • Completed test items: 1.5×PN hydrostatic shell test, 1.1×PN high-pressure hydrostatic sealing test, 4–7 bar low-pressure gas tightness test
  • Water/air pipeline: one-way pressurization and relief; audible/visual alarm at holding-time end

 

Avantages du produit

  • Covers two testing ranges on one bench: DN50–DN250 and DN250–DN600
  • Supports three required test items (shell / high-pressure sealing / low-pressure gas tightness)
  • High/low pressure staged water supply as specified (0–1.6 MPa low-pressure filling; 1.6–15.0 MPa high-pressure system)
  • Bottom circulation tank with rust inhibitor (powder) as specified, to reduce corrosion of valves and pipelines
