NAF all over the world and the Safe Partner
A wide range of globe valves
for manual, on/off and control applications
Flowserve NAF Control valves continues to demonstrate its commitment to provide superior technology for all rotary valve products. The NAF-ProCap is a high-tech valve for chips filling, one of the most critical applications at a Pulp Batch digester plant. It’s crucial that this is done in a safe and time-saving way and to control the time of the cooking sequence.
Ball Valve for applications with erosive and abrasive media. Gives less maintenance and longer lifetime.
Tilting disc check valve. Unique design gives excellent tightness and minimizes pressure shocks.
Reliable two-piece ball valve for a tight shut-off. Designed for the most demanding applications .

A high performance intelligent positioner with high air capacity andunique possibilities for diagnoctics
Welded ball valves siuitable for a wide range of applications
A safe way to remove particles from your process
V-port ball Sector valve with excellent control valve characteristics
High performance butterfly valve. Triple offset disc for tight shut-off and to eliminate seat wear.
Heavy-duty actuator for high performance modulating control
A cost efficient, hight quality three- piece ball valve, with various connection. Available as metal or soft seated version
NAF-Trunnball is an excellent solution where media and extreme pressure conditions make severe demands on design, material and performance.
Equipped with NAF´s unique pre-load self adjustable double stem packing.
The trunnion mounted ball design provides excellent control performance and tightness in both directions, even at high differential pressures.
Service-friendly due to the off-center body split and modular design.
NAF-Trimball is available with two different noise and anti-cavitation trims.
A-trim gives the highest noise reduction for clean medias. The ball has a large number of small zigzag channels to take the pressure drop in several steps. When the valve is opening the channels will be opened one by one and up to 45° the flow is forced to pass the channels twice.
NAF-Trimsector can be used in a wide variety of applications and meets the highest demands for control accuracy.
The unique patented Z-trim design reduces noise and cavitation by taking the pressure drop in several steps.
NAF-Trimsector can be used for medias with impurities or fibres and have a self cleaning effect.
QUICK OPENING GATE VALVES
Quick-Opening gate Valves specialized for draining and blow-out
The pressure in the valve com presses the stem sealing. This provides excellent tightness at high pressure.
