The plug is made of Ductile Iron and fully encapsulated with EPDM or NBR rubber, providing leakage tight sealing and making it suitable for vacuum working conditions. Thanks to the encapsulation, the plug is alsofully protected against corrosion. The abrasive particles are prevented to enter the bearing area bycompression between the rubber and the PTFE thrust gasket.

An overlay with minimum 90% pure nickel is welded over the seat area for long term corrosion resistanceand improved tightness over the plug valve life.

The stem seal design is self-adjusting. It is isolated from the plug stem and external torque device and isunaffected by pressure variations.

The rubber encapsulated plug sealing surface matches the nickel alloy seat and the plug stem located inbody and bonnet, making relative position of upper and lower stem towards sealing surface unchanged. It ensures continuous low torque operation.

The port design with improved internal contours gives high capacity straight through flow in the full open position. It reduces the turbulences and pressure drop and increase the capacity for immersed solids in the medium.

The rectangular port eccentric plug valves offer a 100% port area to provide high capacity flow.

Round port available from 2" to 12".

High strength ductile iron body used for lowering the weight and improving long term durability.

All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance per AWWA C550.

fBearings are permanently lubricated, oil impregnated sintered SS316.
