Double Offset Metal Seat High Performance Butterfly Valves
High Pressure, High Temperature, Bi-directional, Zero Leakage Butterfly Valves
The double offset metal seat high performance butterfly valves characterized an innovative design that offers superior long service life and extremely easy maintenance in the field. Wear-resistant metal seat provides industry leading low torque.The stem is one piece blowout-proof, Square end connect to operator. Rigorously 100% internal tests prove Class V bi-directional leakage rates through full pressure range. Third-party inspections will be performed on the customer's request.
