Product Description

Ball Type Check Valves Castings (NRV) - Flanged (High Pressure model: R-01)

RUMAX Ball Type Check Valve (NRV) involves a very simple but robust design with no critical mechanism involved. Parts like Hinge, Pin, Disc etc., used in conventional Non Return Valve (NRV) are eliminated. This Ball Type Check Valve (NRV) works excellently in muddy / clear water, viscous liquid, paper stock, slurries, erosive and corrosive fluids.


* Innovative   * Maintenance Free  * Totally Leak Proof



Ball Type Check Valve (NRV) - Flanged  (High Pressure model: R-01)

PRINCIPLE OF RUMAX BALL TYPE CHECK VALVE (NRV)

RUMAX Ball Type Check Valve (NRV) 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 BALL TYPE CHECK VALVE (NRV)

* Lower power consumption * Larger solid handling capacity * Self cleaning, Non-Clogging

* Perfect Sealing * Low pressure drop * Maintenance free, replacement of ball is very easy

* Works excellently in muddy / clear water, viscous liquid, paper stock, slurries

COMPARISION

RUMAX Ball Type Check Valve (NRV)

CONVENTIONAL NRV

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.

The sealing face is deposit free, since it remains inclined in any position of the valve, ensuring perfect sealing.

Deposits on the sealing due to its flatness may not ensure perfect sealing.

Clear passage, equal to nominal valve dia. gives larger solid handling capacity

The Disc interference leaves less clear passage than the normal valve dia., hence smaller solid handling capacity

Abrasion resistance of rubber ensures longer life. Also the cleanout port does not necessitate valve removal from the pipeline. Hence much shorter downtime.

Parts may wear out due to abrasion. Also, valve may be removed from the pipeline for maintenance/ cleaning. Hence longer down time.
