Features
The self-centering seat ring and sturdy spool provide tight shut-off performance for both forward and reverse flow.
The one-piece body flange can match many different types of pipe flanges to meet various pipe requirements.
Streamlined channels, sturdy and durable parts, a wide selection of corrosion-resistant trim materials, all of these make the valve a long and reliable working life in the case of aggressive media.
The eccentric valve core reduces the contact friction with the valve seat ring during opening, thereby reducing the wear of the valve seat.
Carefully selected trim materials and body coatings help withstand oil sands, supply furnaces, and other highly corrosive applications.
Rugged metal or VTC seat rings and valve plugs provide tight shutoff of fluids without deformation of the plug stems and the need for thinner gaskets.
No special positioning, precise clamping, or centering of the valve plug and seat ring is required before tightening the pressure ring, which improves the accuracy of alignment and ease of assembly.
