Description
Technical Specifications
SPECS wafer V-port segment Ball Valve is concentric segmental Ball Valve for modulating and cutting-off applications. V-notch cut at disc makes rangeability larger and
creates shearing effect by disc and seat ring. Therefore, suitable to large rangeability service and/or control of fluids with fiber and/or slurry.
Applicable Standards
Design & Manufacture Standard: IEC 60534-2006
Face to Face: Manufacturer's standard
End Connection: ASME B16.5, EN1092-1, GOST33259, JIS
Test Standard: IEC60534-4
Products Range
Size: 1"~10"
Pressure Rating: ASME CLASS 150~300
Material: Carbon steel, Stainless steel, Alloy steel, Duplex stainless steel
End: Wafer (RF)
Temperature Range: -29℃~350℃
Seat Leakage：ANSI IV or ANSI Ⅵ(bubble-tight)
Design Features
1. Body
Single-piece body prevents leaks caused by separate flanges or locking rings.
2. Stem
Stem is finely grounded to match actuator excellently, which prevents rocking motion and potential failure of the V-port segmented valve.
3. Self-lubricating bearings
The upper and lower valve stems are fixed by self-lubricating bearings, which have high rotation precision and good rotation stability.
4. V-port segment ball
Designed with a specially shaped V-notch to allow the valve to have approximately equal percentage flow characteristics. At the same time, a large shear force will be generated between the segment ball and the seat during the movement. It has excellent wiping performance and is especially suitable for applications with viscous media, fibers and solid particles.
5. Seat
The valve seat is preloaded by a disc spring, so that the seat is always in close contact with the segment ball, and the sealing performance is good, it can automatically compensate the sealing pair, ensure reliable sealing.
6. Seal Surface
Nitriding/Tungsten Carbide/Stellite Alloy/Nickle Base Alloy plating are available for abrasive media.
