Design Features:Valve Type: Double Offset Butterfly Valve with Soft Seat.Offset Design: The valve stem axis is offset from both the sealing surface and the pipeline axis. This allows the disc to quickly disengage from the seat during opening, greatly reducing friction and wear and extending seal life.
Sealing System: Resilient soft seat (typically EPDM, NBR, PTFE, etc.), providing excellent elastic sealing and achieving bidirectional zero leakage (compliant with standards like ANSI Class VI).
Body Material: WCB Carbon Steel, offering good structural strength and general pressure resistance.
Disc Material: CF8 Stainless Steel (304), usually with a polished or coated surface to ensure tight contact with the soft seat and resist corrosion.Connection
Design: Semi-Lug Body. Can be installed via through-bolts like a wafer valve but includes tapped lug holes to support the valve during disassembly of one side of the pipeline, facilitating maintenance.Actuation: Hydraulic Actuator, delivering high torque, fast response, and suitability for applications requiring quick operation or high differential pressure to open. Can be directly integrated into hydraulic control systems.
