Collection:TamesonPRO 1125 3-Way Stainless Steel Ball Valves ISO 5211

The TamesonPRO 1125 series includes 3-way stainless steel ball valves with ISO-Top actuator mounting pads, rated for 69 bar at 20°C (1000 psi at 68°F) working pressure with PTFE seats. They are available in both L-port and T-port flow configurations, with G thread sizes from 1/4'' to 1-1/4''.

The L-port configuration directs flow between two of three ports at a time, functioning as a diverting or selecting valve. The T-port configuration allows flow between all three ports simultaneously, enabling mixing or distribution. Both variants include ISO-Top mounting flanges (F03/F04 for sizes up to G 3/4'', F04/F05 for G 1'' and G 1-1/4'') for actuator attachment.

When selecting from this series, first determine the required flow pattern: L-port for diverting or T-port for mixing. Then choose the appropriate thread size (G 1/4'' through G 1-1/4'') and confirm the ISO-Top flange size matches the intended actuator.
