DeZurik 18" Eccentric Plug Valves, Cast Iron Body, Chloroprene (Neoprene) Soft Rubber Lined, Acrylonitrile-Butadiene V-Type Adjustable Packing, ANSI 125/150 Flanged Ends, EIM Electric Motor Actuator (2FSG-3), 480V/60Hz/3Phase, 1 HP Motor. These valves are ideal for on-off corrosive and abrasive slurry service.

FIG198 SOFT RUBBER LINED ECCENTRIC PLUG VALVE
Eccentric action plug moves into and away from the seat, which eliminates abrasive wear. Heavy duty stainless steel bearings with grit excluder seals assure long, trouble-free life. Body of cast iron. Multiple V-Ring packing provides reliable stem seal. Valve body flange faces and all internal body, plug and cover surfaces are lined with soft rubber to resist abrasion. Pressure Rating: 150 psi (1035 kPa) C.W.P.
Valve Design
Compression fit where lining contacts hard rubber bearings and meets rubber lining on plug at top and bottom journals excludes abrasive particles and seals metal surfaces of body and bonnet from contact with corrosive fluid.

Top and bottom journals furnished with permanently lubricated stainless steel bearings.

Adjustable multiple V-ring PTFE packing prevents stem leakage and compensates for packing wear.

Large port opening and straight through flow path minimize turbulence and wear caused by impingement.

Valve body flange faces and all internal body, plug and cover surfaces are lined with soft rubber to resist abrasion.

Grease fittings in top and bottom journal bearings p rovide for easy lubrication
and aid in preventing solids from forming or entering the journal area. This is standard on cast iron and optional on hard rubber bearing.

Proper Installation
The proper installation of the DeZurik FIG198 Soft Rubber Lined Valve in a slurry application is critical to prevent solids from packing into the valve body, restricting the plug movement. This can be accomplished by installing the valve with the flow against the face of the plug in the closed position and the valve on its side with the plug rotating to the top of the pipeline in the open position. Where the possibility of overhead drainback exists, the valve should be installed with the plug facing in the overhead drainback condition. The DeZurik FIG198 Soft Rubber Lined Valve is not designed to be a throttling valve. This valve should be operated to either the full open or full closed position.
Open
Install valve so plug rotates up 90° to open. This prevents sediment from sticking plug open.
Shut
Flow against face of plug prevents solids from packing in body cavity while shut. Where there is no chance of overhead drainback, install valve with flow against face of plug. Install valve laying on its side so plug rotates 90° to open. This keeps plug and journals free from sediment.
Slurry in Vertical Line
Where the possibility of overhead drainback exists, install valve with flow against back of plug. This prevents drainback solids from packing into body.

Soft Rubber Lined Eccentric Plug Valve in Slurry Service
The DeZurik FIG198 Soft Rubber Lined Eccentric Plug Valve has proven to be an excellent valve selection for on-off corrosive and abrasive slurry service. DeZurik soft rubber lined valves are used in ash handling systems, scrubber circulating and effluent discharge, thickener feed and under-flow, ball and rod mill feeds, classifier feeds, reclaimed water, and tailing systems. The combination of the raised seat and eccentric action allows solids to be wiped away to provide positive closure. The quarter turn action of the valve contains all process media inside the valve body. There is no discharge to the outside environment each time it is operated. Because the valve is normally mounted in reverse flow in a slurry application, it is recommended that the seat be exposed when pressure is in excess of 100 psi (690 kPa) to insure drip-tight shut-off. The FIG198 Soft Rubber Lined Valve is available with hard rubber bearings in lieu of the standard stainless steel, and the stainless plug in lieu of the standard cast iron. These valves can be used with flows upto 11 Feet/Second or particles up to 1/16" (.0625mm).
