FC | FIFTO | NELES FINETROL ECCENTRIC ROTARY PLUG CONTROL VALVE, METAL SEATED, FLOW-TO-OPEN |
The Finetrol eccentric rotary plug control valve in standard flow direction (flow-to-open = flow through the seat ring and past the plug) is a rotary control valve with eccentric, 90 degree rotation, contoured plug. Finetrol is suitable for controlling liquids, gases and steam in a very wide range of services. Temperature range -200 ... +425 °C. One reduction (50 % of full port Cv) per size is available. However, for DN 25 (1") valve, three different reductions are provided. Flanged ANSI 150...600 sizes DN 25...250 (1"...10"), PN10...PN40 sizes DN25...250 (1”-10”).
