The NAF Setball for Middle Consistency (MC) pulp is a ball sector valve with metal-to-metal seating and combines the best control characteristics of the ball valve and the butterfly valve. It can be used both as control valve and as shut-off valve and is available in flanged version. This valve type is developed for MC-pulp 8-19%. It has an enlarged outlet with one size bigger flange on the outlet to get an excellent flow characteristic for the MC-pulp out of the valve. It is available as standard in 1.4408/CF8M, CG8M and SMO254.
