China centerline wafer butterfly valve feature
1. Integrally molded seat liner on the body, which ensures excellent dimensional stability & guaranteed seat tightness.
2. Seat liner extending on to the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
3. Unique triple sealing system for shaft sealing ensures zero leakage of the media past the shaft seals.
4.Narrow land disc ensures perfect sealing with least operating torque requirements.
5.A fully universal body design ensures fitment of the valve between companion flanges of all popular standards (ANSI, BS, DIN, JIS, GB.etc. ).
6. Several position notch disc and hand lever ensures locking of the valve in 8 intermediate position in addition to closed and open position. Hand
7. Lever lockable through pad lock for tamper proof positioning.
8. Body castings made of superior material to ensure additional strength.
9. Wafer butterfly valve disc made of ductile cast iron instead of cast iron to withstand against possible water hammer or pressure surges.
10. A truly line size body bore to ensure maximum flow capacity with the lowest pressure drop.
11. Shafts made of martensitic stainless steel to ensure maximum strength and torsional rigidity.
12. Both top and bottom shaft swiveling are guided by self – lubricated bearings.
