toneL VCT platforms feature fully sealed, solid state, modular electronic systems warranted for a full five years. A solid state magnetic resistive sensor provides continuous position feedback in the C-Module used in the AXIOM platform. Dual inductive position sensors provide feedback for the Dual Module used in the ECLIPSE, PRISM and QUARTZ platforms. On-board microprocessors, position sensors, output controllers and more are included to consistently operate the valve-actuator assembly and precisely communicate parameters to the plants control system. C-Module Used in the AXIOM platform, the C-Module (Continuous sensing) integrates a magnetic resistive sensor system to monitor exact valve position throughout the rotational range. Push button or remote Open and Closed position setting along with microprocessor based operation make this state of the art system convenient, reliable, and smart. Dual Module Used in the ECLIPSE, PRISM, and QUARTZ platforms, the Dual Module (Dual sensing) integrates two inductive sensors to directly monitor Open and Closed valve positions. Settings are made by adjusting cams with stainless steel targets for simple and reliable operation.

Exclusive Memoryseal seats compensate automatically for wear and fluctuations of pressure and temperature.Unique 4-Way and 3-Way packing arrangements for superior stem sealing (refer to page 7 for details).TA-Luft certified.Multiple solid cup and cone type PTFE stem seal and graphite packing.Stem guides prevent side thrust.Long cycle lifeLow, uniform torques.Blowout-proof stem.Fully enclosed PTFE body seal.Metal-to-metal contact between insert and body act as secondary seal and prevents overcompression of the seats.Pipe flange gasket acts as third precautionary seal as threads from the insert are within the raised face flange.Meets worldwide specifications. Design ASME B16.34, BS 5351, API 608(2), fire tested to API 607 Rev. 4, BS 6755 and API 6FA. ISOCAPI for all parameters of standardized valve automation.Locking device standard for valves with lever handle.Highest standards of quality. Over its 50 years of production activities Velan has earned a worldwide reputation for quality in design, manufacturing and valve performance.

Off-center split-body design allows the use of advanced spiral-wound gaskets.Maximum temperature for CF8M 1, 000F (538C), forWCB800F(426C).Full port ensures large capacity and reduces the risk of clogging when handling solids or slurries.Wall thickness complies with ASME B16.34 and BS 5351 for 2-12" ASME 150 and 300 full port only.Stem bearing reduces side thrust effect on packing and prevents stem wobbling.Integral seat locking option does not require additional parts or special tools.Scraper seats standard.Ball and seats lapped for optimum performance and tight shutoff.Low emission stem seal.Blowout-proof stem.Two-piece flanged gland. Live-loaded as standard.All valves with graphite packing and backup seal are inherently fire safe.Can be used for manual throttling applications. (For automation contact Velan Engineering.)Manual operation with handle for 2-4" (50-100 mm) FP and 3-6" (80-150 mm) RP. 6" (150 mm) FP, 8" (200 mm) RP and larger require gear or actuator. Gear or pneumatic actuator available.Tightness rates: Allowable leakage rate at full Delta P: ASMEFCI 70-2 Class V. Tighter shutoff available upon request.Oversized ball to stem connection provides: - No deformation of the stem slot in the ball. - Better throttling control performance. - Less motion loss and wear in automatic on-off applications.
