Microflow Control Innovation
Optimized CV Characteristics
The VariPak valve outshines conventional microflow valves with its sup­port of a wide range of nominal Cv values (from 0.0016 to 3.8), using only eight plugs and five seats.

Varilog* Anti-Cavitation Varipak
28000 MS Series
The Varilog multi-stage trim design for the Varipak control valve provides unmatched anti-cavitation performance in low flow applications.
By reducing erosion and vibrations, this design helps minimize failure that is often associated with conventional single-seated valves. The Varilog trim is available with the standard Varipak body designs in either the flanged or flangeless configurations.

Cryogenic Varipak
28000 EB Series
Simplified maintenance This Varipak control valve design meets the requirements of cryogenic process­es that require thermal insulation. An insulating interface sets up between the valve body (cold zone) and the body extension located in the higher temperature area (warm zone). The valve body assembly and its thermal extension are po­sitioned inside the cold box, and the plug can easily be removed and inspected without disturbing the valve body. This eliminates the need for any preliminary, complicated dismounting, and more importantly, prevents any interference with the cold box.
Body Manufactured from a material suitable for low temperatures, the valve body maintains ductility in service. It can be conveniently mounted to suit specific piping needs, as long as the angle between the valve axis and vertical does not exceed 60°.
Specific Characteristics
The bonnet is located away from the cryogenic fluid, which means that the body gasket is not inside the cold zone. This design prevents any leakage of the cryogen into the insulated zone.
Body extension To reduce the inflow of head by conduction, thin-walled metal tubes are used for the body extension and coupling sleeve. In addition, the annular space is reduced to exclude convection currents.
Plug The design of the plug allows the working parts to be accurately centered in relation to the seat and provides a uniform temperature zone for the guiding.
