The Fisher Vee-Ball Valve Family

Vee-Ball rotary valves combine the features andperformance you need. These features are made available through expertise in applications, valvedesign, and manufacturing.The valves are suitable for throttling or on-offservice. They are often used with a full 0 to 90degree ball rotation. Fisher V150, V200, and V300 Vee-Ball valves usethe time-proven V-notch ball that provides high-capacity control of liquid, gas, steam, andfibrous slurries. The shearing action of the ballallows smooth, non-clogging operation, and the unrestricted, straight-through flow ensures highcapacity.
W74351/IL Figure 2. Fisher V150 or V300 Valves Easy Installation . . . Fisher V150 and V300 integralflanges eliminate exposed flange studs, and theV200 features line-centering lugs to simplify alignment. Easy Seal Inspection . . . Seals can be inspectedwithout removing the actuator or disassembling thevalve. High Rangeability . . . Flow coefficient ratio is 300to 1. Noise Attenuator Ball. . . Depending on serviceconditions, up to -10dBA acoustical attenuation anda K Reduced Maintenance Costs . . . The V150, V200,and V300 valves have interchangeable trim parts toreduce spare parts inventory and cost and simplifymaintenance procedures and training. Metal and soft seals are interchangeable within a valve body.
C of 1.0 for liquid flow are possible with the noiseattenuator ball (available with DN 100 through DN300 and NPS 4 through 20 valves). Basis Weight Control Valve . . . Fisher V150,V200, and V300 valves are available to meet the precision control requirements of basis weightcontrol in the paper-making industry. Protection Against Process Fluid Emissions . . . Optional ENVIRO-SEAL packing systems provide anexcellent shaft seal to prevent the loss of valuable orhazardous process fluids. These live-loaded systems provide long packing life and reliability. Other Rotary ProductsFisher Materials for Sour Service . . . Emerson ProcessManagement offers materials and manufacturingprocedures for compliance with NACE (NationalAssociation of Corrosion Engineers) standard NACE MR0175−2002, MR0103, and MR0175 / ISO 15156. V500 Valve . . . The V500 valve usesrugged valve components and a choice of erosion-resistant trim materials for highly erosiveand severe operating conditions at pressures to PN100 (CL600) and temperatures to 538 C. Fisher CV500 Valve . . . The CV500 combinesthe rangeability of the cammed-segmented V-notchedball, with the inherent ruggedness found in the V500 heavy duty bearings, seals and body. Thiscombination provides a balance of high capacity,erosion resistance, and pressure control for liquid and gas.
