Flowrox Rotary Disc Valve (LRD)

Flowrox Rotary Disc Valve is built with a cast body and features a heavy-duty stainless steel gate. LRD is a unique rotating disc valve designed specifically for heavy abrasive and corrosive slurries. The patented design allows the valve to cycle in heavy slurries without sticking or leaking and with minimum wear.

LRD is available with pressure ratings from 10 to 100 bar.

How the valve seals work?

LRD is a rotating disc valve for slurry. The isolation and sealing is between the replaceable rotating disc and seat. 

The disc seals against the seat when closed with the help of a tapered wedge gate support.  The seat can be supplied in elastomer urethane or ceramic. This rotating disc and seat are both replaceable on site.  

Replaceable discs

LRD valve's design allows for on site replacement of the rotating disc.
