SEGMENTED BALL VALVE (V TYPE BALL VALVE) PRODUCT RANGE: Sizes: NPS 1 to NPS 20 Pressure Range: Class 150 to Class 600 Flange Connection: Wafer, Flange (RF, FF, RTJ) MATERIALS: Casting (A216 WCB, A351 CF3, CF8, CF3M, CF8M, A995 4A, 5A, A352 LCB, LCC, LC2) Monel, Inconel, Hastelloy STANDARD Design & manufacture ASME B16.34 Face-to-face -Flange: ANSI/ISA 75.08.02 (ISA S75.04) / IEC 60534-3-2 -Wafer: NSW MFG'S Standard End Connection ASME B16.5, EN 1092-1 Test & inspection API 598, ANSI FCI 70-2 Fire safe design API 6FA, API 607 Also available per NACE MR-0175, NACE MR-0103, ISO 15848 Other PMI, UT, RT, PT, MT Design Features: 1. Preeminent performance of adjustment control The ball is of "V"pattern.At any position from full open to full close,it always keeps the standard geometry.The large adjustable extent is from 100:1 to 200:1,the CV curve of discharge characteristic is similar to the percentage curve,which may realize the precise control of the flow. 2. One piece body One piece integral body,the strength is high,stress deformation resistance is strong,has no central flange,confinement reliability is improved,has no bending transition at the flow passage,not accumulate,not block,has little influence upon the fluid. 3. Eliable seat sealing The sealing surface build-up welding is handled by hard facing and employ the advanced seat grinding technology and griding ball technology to make V type ball valve have reliable sealing performance which can achieve the V sealing grade of ANSI B16.104 specified.The special requirement can achieve VI grade. 4. Ball The ball hard surface handled by STL,tungsten,etc.Both the two ends are V pattern,which is easy to precise control for flow also can realize the shearing action for the fluid containing cellulosic,the high-viscosity fluid containing solid particles when shutting. 5. Sealing packing The stem adopts the adjustable jam type packing of V type PTFE or RPPL.Ensure that has reliable sealing and no out leakage under the middle and high temperature.
