Application Flexibility
One size hardly ever fits all applications. That’s why the Varipak valve offers the flexibility of 10 standard contoured trim designs based on the same body platform. These multiple trim sets help reduce the effects of valve oversizing and improve control loop performance, resulting in better process efficiency.
Adjustable Flow Coefficient (CV)
With the valve’s adjustable Cv option, you can easily accommodate changing operating conditions. The Cv
value can be increased or decreased simply by setting a knob within the actuator assembly.
Anti-Cavitation Trim
Varipak is available with an effective high-pressure, liquid let-down, anti-cavitation trim solution – the Varilog™ trim. This unique design includes a multi-stage axial flow plug and liner, which provides dirt-tolerant operation and high wear resistance.
Flow characteristics with large turndown
The valve has a linear flow characteristic with a turndown of up to 500: 1 on the CV value, which ensures that you can control the process very precisely over the entire flow area.
Ease of Maintenance
Varipak control valve’s simple, top-entry, body construction includes an integrated body and bonnet design, which allows for easy access and removal of the quick change trim. The integral liner and seat ring construction reduces the number of components, simplifying assembly and disassembly. In addition, the modular actuator design further enhances the maintainability of this unique valve assembly.
