The Masoneilan 33000 Series by Baker Hughes leverages exclusive patented engineering and sophisticated manufacturing processes to integrate triple offset geometry, granting bidirectional sealing capability. The product line maintains fully tight isolation shutoff over wide pressure and temperature operating envelopes, covering continuous modulating control and discrete on-off process requirements.Low operational friction is attained through the disc’s third offset angle and metal-to-metal seat pairing. This mechanical arrangement preserves bubble-tight isolation sealing for two primary service modes: complete on-off isolation and precise high-range throttling control.As a heavy-duty triple offset butterfly valve solution, the 33000 Series delivers outstanding zero-leakage performance. Its streamlined construction offers significant cost advantages relative to larger gate, globe and ball valve solutions widely utilized in process isolation systems.
