Flowserve NAF Control Valves launches the new NAF Trunnball DL full port, trunnion-mounted ball valve.

The NAF Trunnball DL is a full-bore trunnion-mounted ball valve, developed using NAF’s 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
