RANGE OF APPLICATIONS VOLK metal seated ball valves are used when bubble tight shut off, zero leakage is required for one or all of:High temperatureHigh pressureErosive fluidAbrasive fluidSolid laden fluidFast operation from Open to CloseFire Safe designTYPICAL APPLICATIONAs the flagship of VOLK FLOW CONTROLS, INC., the Zero Leakage Metal Seated Ball Valves are widely used in power plants where tight shutoff is needed under high temperature and high pressure operations and are the best choice to replace the old type globe valve. For supercritical units, special valves with F91 materials providing Zero Leakage operations are used.At present, over 50,000 VOLK Valves are operating safely for drains, vents and blow down etc., in more than 500 power plants.2MISSON STATEMENTPROVIDE TOP QUALITY PRODUCTS USING EFFECTIVE QA AND MANAGEMENT SYSTMES AND PROCEDURES PROVIDE THE VERY LA TEST TECHNOLOGY BASED ON RELIABILITY AND PERFORMANCE FROM THE INSTALLED BASE PROVIDE THE VERY BEST IN INDUSTRY AFTER SALES SERVICE AND SUPPORT TO THE CUSTOMER BASEIn Power Plant processes, high temperature, high pressure andother severe conditions coexist, therefore, the use of zeroleakage, bubble tight valves is very important.Regardless whether it is for draining water, disposing of waste,or disposing of steam, having a valve that leaks translates intohuge losses for any Power Plant. VOLK’s high quality steamcontrol products are not only used to achieve zero leakage, butalso to prevent a Power Plant from the inconvenience of leak-age problems. Internal leakage translates into the unnecessaryloss of money and time; in addition, external leakage threatensthe safety environment of the factory.VOLK VALVES IN POWER PLANTSVOLK V13VOLK metal-seated hard coated ball valves series completelysatisfies the demands and requirements of any Power Plant. Inall severe service operations, VOLK valves provide outstandingperformance with ZERO LEAKAGE.VOLK’s ZERO LEAKAGE GUARANTEE applies to both inter-nal and external leakage.VOLK valves perform with little to no maintenance, thus reduc-ing the cost of Plant operation. VOLK valves are all the user needs to completely solve their valve-related performance problems. VOLK get it right, the first time, every time.VOLK V2VOLK V3QUALITYVOLK’s complete in-house machining, coating, assembly and testing along with material traceability and extensive quality procedures ensure customers a top quality product at a very competitive price.

Double Stem Blow out ProtectionA special designed gland bushing ensures the correct alignmentof stem and at the same time prevents loading the stem to thepoint where it could push the ball through the seat.4. Reliable packing gland design and the use of belleville springsprovide long lasting, maintenance-free, stem packing seal andtightness.5. Isolated Body CavityThe ball and seat are in full constant contact, isolating the bodycavity from flow to prevent build-up of solids6. Quarter Turn ValveLess torque is required to operate the valve due to a top andbottom fully guided stem and life-lubricated thrust bearing whichreduces torque. It’s quarter turn operation and zero leakage makethis valve ideal for Emergency Shut Down applications.7. Locking Device The locking device prevents mis-operation and ensures that the valve opens and closes at the cone position.8. Application of HVOF Coatings The ball and seat are chromium or tungsten carbide impreg-nated by HVOF coating techniques with surface hardness of Rc 68-72 and are mate-lapped to a very high RMS finish (0.05 mi-cro meters RMs), providing Zero Leakage, and long, mainte-nance free service life.9. Inconel 718 Belleville Spring The Belleville Spring maintains tight constant contact between seats and ball, therefore protecting seats in an open and closed position and allowing valve to seal bubble tight under both high and low pressure operations.10.
