| A new, technically advanced valve trim for extreme process conditions from Weir Valves & Controls. |
The new Weir Valves & Controls X-StreamTM trim has been specifically developed
to eliminate problems of erosion, cavitation and noise on both your severe and problematic services. Through it’s unique flow
path design, consisting of a multitude of staggered cylinders, the X-StreamTM is the first of its kind to provide complete 3D-flow control. The result of an extensive
research programme, this method of design uses a combination of proven computational fluid dynamics (CFD) and actual flow
visualisation techniques to eliminate local areas of excessive turbulence and velocity (the main source of noise and erosion
problems) and areas of recirculating flow (a significant cause of cavitation).
Features and benefits
leading to reduced noise, cavitation, erosion and vibration problems on severe service/high-pressure
applications.
Trim design equated to up to 40 stages of pressure letdown, keeping extreme velocities and fluid turbulence to a minimum.
Natural self-cleaning/anti-clogging capabilities reducing possibility of trim blockage on contaminated services which
would result in poor flow control and expensive maintenance costs.
Suitable for liquid, steam and gas applications as a solution to potentially excessive noise, cavitation, vibration
and erosion problems.
Custom designed to meet individual application needs, incorporating linear, equal percentage and custom characterised
flow characteristics.
Single unit cage guided trim design allowing quick installation and removal. Available for retrofit or as complete
control valve package by incorporation into both the BV500 and BV990 range of Hopkinsons globe and angle valves.
