Flowserve NAF is a market leading company established in 1899. In 1904, the company delivered the first stainless steel valve to the process industry. And in 1933, the company presented the first ball valve to the world.  With years of experience and product innovations, NAF is today one of the most successful manufacturers in effective control of demand flow focused on the pulp and paper industries.

By means of its own development resources and affiliated companies within the group, NAF has a unique combination of new techniques, experience of process control and traditional valve expertise. With this background as well as having a strong brand name in control valves, NAF are among the leaders in the development and future of intelligent flow control systems.

NAF Du-Ball consists of a 2-piece heavy duty ball valve suitable for both on-off and modulating services. Its robust design and excellent tightness in both flow directions, is due to the floating ball valve design. The NAF Setball is a sector ball valve with excellent control characteristics. The design is ideal for modulating services on almost any type of fluid, and also for those with particles, in pressure class 150 and 300.  The NAF-Trimball are for serve service application where difficult media and high pressure drop are present, causing cavitation and noise. Another ball valve variant is the NAF-Ceramic valve that is used on erosive and abrasive media.

The NAF-Torex is a high performance butterfly valve for control, on/off applications and shut off applications, The triple offset design guarantees excellent tightness and minimum wear. The modular design assembly makes the valve very versatile for actuation and manual operation.
