Wafer Ball Valves
Wafer ball valves clamp the short-cased body between pipeline flanges instead of carrying their own flanges, cutting face-to-face length, weight and cost on general isolation duty where the slim body is acceptable. The range covers DN15 to DN150 at PN16 to PN40 / Class 150 to Class 300, with WCB, CF8 or CF8M bodies and balls, PTFE seals, manual, electric-actuated or pneumatic-actuated operation, ASME B16.34 design, flanging per ASME B16.5 / JIS B2212 / DIN 2543, API 598 testing, and a full DN-by-DN dimension table (bore, flange diameter, length, handwheel, height, bolt pattern) from DN15 to DN150. Selection turns on the flange standard of the mating pipe, the pressure class against line rating, and manual versus actuated operation.
