Triple Offset Butterfly Valve-Durco TX3

The Durco TX3 triple‑offset butterfly valve delivers superior shut‑off performance while reaping the operational advantages of low‑torque actuation and minimized component wear. Its precision‑machined seat and sealing surface are manufactured at an offset angle, which distributes uniform contact load across the full circumference of the seat ring and eliminates rubbing friction between seat and seal during valve opening and throttling travel. Paired with a high‑performance laminated seal ring, this triple‑offset geometry delivers long‑service‑life, bi‑directional, bubble‑tight shut‑off, even for gaseous‑media operating conditions。
