- Excellent Flow Characteristic—Precise contouring of V-notch ball provides a modified equal percentage flow characteristic.
- High Capacity—Unrestricted, straight-through, flow design provides greater capacity than many conventional globe and rotary eccentric plug valves.
- Long Seat Life—Patented V-notch ball cams into and out of the seat minimizing contact with the seat ring for reduced wear and friction. V-notch ball doesn't contact seat during throttling operation. S31600 (316 stainless steel) or R30006 (Alloy 6) seat ring has two shutoff surfaces and can be easily reversed, reducing downtime.
- One-Piece Body—Valve body is cast in one piece. There are no body gaskets to leak as a result of pipeline stresses.
- Operational Versatility—Self-centering seat ring and rugged V-notch ball allow forward or reverse flow with tight shutoff in either flow direction.
- Easy Installation—Integral valve flanges mate with many different classes of pipeline flanges, satisfying a variety of piping requirements. Flanges eliminate exposed line flange bolting, shorten alignment and installation time, and promote secure valve installations and piping integrity. Flangeless valves are automatically self-centering on line bolting for easy installation.
- Simple Assembly and Maintenance—No special orientation, precision clamping or repetitive centering of V-notch ball and seat ring is required when tightening the retainer, promoting accurate alignment and easy assembly.
- Sour Service Capability—Trim and bolting materials are available for applications handling sour fluids and gases. These constructions comply with the requirements of NACE MR0175-2002.
- Rugged Construction—Durable, solid metal seat ring and ball shut off tightly. Oversized shaft diameters and rugged trim parts allow high pressure drops.
- Reliable Performance—Patented seat ring design self-centers, self-laps, and dynamically aligns with V-notch ball, giving superior cycle life. Optional sealed metal bearings help prevent particle buildup and valve shaft seizure in severe applications.
