The eccentric plug valve is quarter turn with obstacle-free bore, adapted for pump control shut-off and throttling service with bi-directional flow in applications where wastewater is contaminated with fibrous particles or hydrocarbon residues. The plug is fully vulcanized with hydrocarbon resistant NBR rubber compound which due to its sturdy design, double bonding vulcanization and the rubber's ability to regain its original shape features an outstanding durability. The valve seat is corrosion resistant, welded nickel with a full port design that allows for high flow capability, an ISO 5211 actuator flange is incorporated in the valve housing and fusion bonded epoxy coating protects internally and externally.
Features & benefits of the plug valve include:
1. Eccentric design, lower friction, zero leakage
2. Seat in 90% nickel, welded on the cast body for corrosion protection and extended life time.
3. Bonnet gasket and plug rubber in hydrocarbon resistant NBR according to EN681-1.
4. Round rubber bonnet gasket fits into a groove in the valve bonnet preventing it from being blown out by pressure surges.
5. V-type stem seal packing, easily adjustable during use
6.Self-lubricating, stainless steel backed, PTFE coated, bronze bearings along with upper and lower bronze washers ensures consistently low operating torque.
7. O-ring seals make the maintenance easy.
8. Liner characteristic can be used for throttling purpose.
9. Straight through flow design and columniform body can meet max flow capacity requirements without deposits.
10. The valves can be manual, pneumatic or electrical operated.
