MDV-600/15-2S Horizontal Clamp-Type Butterfly Valve Test Bench

introduzione del prodotto

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).

Descrizione del prodotto

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

Product Advantages

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
