Hi-Fluidic Master Descaling Valve
design concepts
• Pressure compensating-
Through the hole of the sliding discs
• Pressure Balancing by twin ports-
The same offsetting force acting on each port
• Only sliding contact allowed to seal the seatsno
compression sealing required
• Very low thrust force required on the stem-
Due to sliding not high contact stress on the seat sealing
• Disc spring assist force to sealing surface-
Very compact design of valve plug(disc holder)
• Wide flat seat surface & hardfacingseat
is wide and stellite #12 HF
Disc is coated by super hardness ceramic
P
Operation
• spray water flow separated into two flow path and the flow
stopped on each gate
• Twin discs of the plug move to open & close position with
sliding contact on the seats
• apply only a friction force and forces of disc sping
• manual, Pneumatic piston(fail close, fail open, as is position,
Hydraulic operator applicable
• Fast acting tight shut off and flow throttling using speed/
position controller
• selectable normal closed or opened position
