X-Stream™ Severe Service
Control Valve
Severe Service Control Valve for control of high pressure,
cavitation and high noise levels. A new,
technically advanced valve trim for extreme process conditions from
Weir Power & Industrial. The nee
X-Stream™ 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-Stream 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 / Benefits
- Severe service valve for contol of high pressures without
blocking the valve
- Cage trim valve for high pressure letdown
- Valve can be fitted with multiple cages for high pressure
reduction
- Stable cage guiding
- Accurate control of the process fluid
- Simple low cost inline maintenance
- Comprehensive interchangeable parts system
- High flow capacity
- Anti cavitation & low noise trims
- 3D flow control 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.
