Ever since its introduction back in the 1980s, NAF Turnex has proven its unique features and maintenance-free operation. The robust linkage system with bushing provides an optimum torque curve for quarter turn valves and eliminates play. This makes it ideal for rotary control applications. NAF Turnex is an integrated part in the NAF control valve package with a unique direct mounting concept. The actuator is also used for on/off service and has adjustable end-stops in both directions. Ever since we developed this state-of-the-art actuator the spare parts have been the same. This, combined with a unique system of sleeves, for different stem diameters, minimizes the number of spare parts.

The NAF Trunnball DL is a full-bore trunnion-mounted ball valve, developed by Flowserve engineers with more than 80 years of experience manufacturing ball valves. The ball is supported by two large, low friction trunnion bearings for consistent low torque even at high differential pressures. Due to its bi-directional tightness, low friction and high controllability, it is an excellent choice for isolation, on/off and modulating control applications.

The NAF Torex, High-Performance butterfly valve is available with either metal-to-metal or soft seats. Due to its unique design and triple offset, it closes extremely tight. It can be used both as a control valve and as a shut-off valve.This valve can be supplied in either wafer or lugged versions. The valves are also available in other materials e.g. Carbon steel, and Titanium, other stainless steel materials and in Fire-safe design.

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.
