BALL TYPE FOOT VALVE - THREADED
PRINCIPLES OF RUMAX FOOT VALVE
RUMAX has involved in a reinforced rubber coated ball to arrest flow media in return condition. This ball moves totally out of the flow path when the pumping is on, to give minimum head losses (see Figure). The spherical rubber coated ball seals perfectly on the rounded valve seat ensuring a totally leak proof sealing.
EXCELLENT ADVANTAGES OF RUMAX FOOT VALVE
|
* Lower power consumption
* Larger solid handling capacity
* Self cleaning, Non-Clogging
* Perfect Sealing
* Low pressure drop
|
* Maintenance free
* Replacement of spares is a minutes job
* Works excellently in muddy / clear water,
viscous liquid, paper stock, slurries

RUMAX BALL TYPE FOOT VALVE
|
CONVENTIONAL FOOT TYPE
|
|
Innovative design, focused to eliminate all constraints of conventional one and offer optimum performance
|
Conventional design carries lot of constraints.
|
|
Internals designed in such a way that laminar flow is not disturbed to a large extent.
|
Turbulence is generated in fluid flow due to design limitations.
|
|
Very low pressure drop across the valve which saves energy, reduces pump cycle time duration
|
Comparatively high pressure losses, requires more energy increases pump cycle time duration.
|
|
Opening & closing by simple rubber ball mechanism, so maintenance free
|
Opening & closing involves spring mechanism calls for frequent maintenance.
|
|
|
|
This valve must be installed vertically.
