Collection:TamesonPRO 1121 2-Way Stainless Steel Ball Valves 3-Piece ISO 5211

The TamesonPRO 1121 series includes 3-piece, 2-way full bore stainless steel ball valves with Rp (BSP parallel) female threads and an ISO-Top mounting flange according to ISO 5211. The 3-piece body allows the center section to be removed for servicing while the end pieces stay threaded to the pipe.

The full bore matches the pipe diameter for unrestricted flow with minimal pressure drop, and the ISO-Top flange accepts a pneumatic or electric actuator directly, without a separate bracket. They have reinforced PTFE (RTFE) seats and are rated for 69 bar at 20 °C (1000 psi at 68 °F). Select the thread size from the product list and match the ISO-Top flange size, listed per valve, to the intended actuator, confirming the system pressure stays within the rating. For a flanged 3-piece valve, see the TamesonPRO 1124 series.

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