High pressure ball valve for hydraulic pipeline shut off systems

Description:

YUNLINK high-pressure ball valves are designed for hydraulic line isolation, shut-off control and flow switching in mobile and industrial hydraulic systems.

The KHB and KHM series provide 2-way shut-off configurations across a broad range of nominal sizes. The KHB3K and VH3V series provide 3-way switching functions, while the VH2V series provides 2-way shut-off control.

Maximum working pressure depends on the selected series, nominal size and connection type. Selected smaller models are rated up to 500 bar, while medium and larger configurations may be rated at 400 bar or 315 bar.

Multiple connection standards, body and ball materials, seat materials, spindle seals, handle types and surface treatments are available to support OEM, replacement and new-system requirements.
