CE83 5" (DN125) to 8" (DN200) Description
CE83 5" (DN125) to 8" (DN200) Alloy Steel Cage Design, Two Port Control Valves Description The CE83 series is a range of alloy steel two port, cage trim, control valves conforming to ANSI B16.34, ASME VIII standards in sizes 5" to 8" (DN125 to DN200) available with ANSI and PN flange connections. When used in conjunction with a pneumatic linear actuator the ‘C’ series valve will provide characterised modulating or on/off control. Compatible actuators and positioners: Pneumatic actuators PN1000 series, spring-to-close PN2000 series, spring-to-open PP5 (pneumatic) Positioners EP5 (electropneumatic) SP400/SP500 (smart electropneumatic) SP300 (smart electropneumatic) Refer to the relevant Technical Information Sheet for further details. 8 15 16 18 9 11 19 20 21 10 17 13 14 6 12 4 2 1 Globe Control Valves Control Valves Sizes and pipe connections 5", 6" and 8" (DN125, 1500 and 200) Flanged to ANSI 150, ANSI 300, ANSI 600 (Raised face or ring type joint), PN16, PN25, PN40, PN63, and PN100 (Raised face with ANSI face-to-face dimension). 7 3 5 Options Equal %, linear, fast opening (on/off) Trim characteristics, soft seat, hard faced, low noise and anti-cavitation (single and multi-cage).

For conversion Cv (UK) = Cv (US) x 0.833 Kvs = Cv (US) x 0.855 Sizing Please consult Spirax Sarco, Inc. Installation The valve should be installed in a horizontal pipeline with the direction of flow as indicated by the arrow on the valve name-plate. The actuator position will depend on the type fitted to the valve.
