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

The TamesonPRO 1125 series includes 3-way stainless steel ball valves with Rp (BSP parallel) female threads and an ISO-Top mounting flange according to ISO 5211, in L-port and T-port configurations. An L-shaped bore connects two of the three ports at a time, diverting flow from one line to another, while a T-shaped bore can also connect all three ports, for mixing or distributing flow.

The ISO-Top flange accepts a pneumatic or electric actuator for automated switching. They have reinforced PTFE (RTFE) seats and are rated for 69 bar at 20 °C (1000 psi at 68 °F). First choose the flow pattern: L-port for diverting, T-port for mixing. Then select the thread size from the product list and match the ISO-Top flange size to the intended actuator, confirming the system pressure stays within the rating.

TamesonPRO is Tameson's in-house line of industrial components: industrial quality at a fair price, backed by a 5-year limited warranty.
