NAF Trunnball DL Ball Valves FCD NFENTB468-00-A4 09/4 TECHNICAL BULLETIN Experience in Motion
Primary Characteristics 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 bidirectional tightness, low friction and high controllability, it is an excellent choice for isolation, on/off and modulating control applications. NAF Trunnball DL is supplied as standard in stainless steel or carbon steel but is also available in other materials e.g. Duplex, titanium, etc. The valve has: A spring loaded stem seal packing that requires no maintenance and ensures safe operation in automated on/off and control service Direct actuator mounting capabilities of the NAF Turnex actuator which provides a high performance, vibration resistant, compact valve package A sturdy, blowout-proof stem providing high torque transmission with a minimum mechanical backlash for optimum controllability A trunnion-mounted ball providing bidirectional tightness Low friction bearings for low torque and smooth operation The unique Z-trim option that minimizes cavitation and noise and has an excellent control characteristic An extensive size range, DN 50 800, size 6 to 3 An easy-to-service arrangement, due to the off-center joint face of the valve body, which allows for easy replacement of the ball and seals without the need for removing the stem and actuator Metal seats with a rigid welded overlay of Alloy 6 or alternatively, metal supported, reinforced PTFE seats CE-marked according to Pressure Equipment Directive (PED 97/3/EG) module H, category III. For module H, category IV contact NAF.

Actuators The pneumatic actuators NAF Turnex can be directly mounted to the NAF Trunnball DL without any couplings or brackets. Together with the direct mounting capabilities of all NAF positioners and several Flowserve positioners (PMV P5/EP5, PMV D3/D0 and Logix 50 MD Plus), this provides a high performance, vibration resistant and compact valve package suitable for precision control. Please see data sheet for further information on the NAF Turnex actuator capabilities and all other available accessories. 8
