Butterfly valves are quarter-turn valves that control fluid flow through a rotating disc. Featuring a compact structure, low weight, and fast operation, they are widely used in water treatment, chemical, power, petroleum, and HVAC systems. Available in wafer, flange, welded, and clamp types, with manual, electric, pneumatic, or hydraulic actuators. Soft and metal sealing options ensure reliable performance across various pressures and temperatures, offering efficient and economical flow control for industrial applications.

Key Features & Advantages
• Compact & lightweight: 30% smaller and lighter than ball valves.
• Quick operation: Full open/close within 90°, under 30 seconds.
• Low pressure drop: Flow resistance ≤0.1 MPa for energy saving.
• High pressure tolerance: Soft seal ≤1.6 MPa; hard seal ≤6.4 MPa.
• Wide temperature range: EPDM ≤120 °C; PTFE ≤180 °C; metal ≤600 °C.
• Reliable sealing: STL alloy seat + O-ring prevent leakage.
• Easy maintenance: Seal replacement reduces downtime by 50%.

Ball valves are quarter-turn valves that use a precision-engineered spherical disc to control the flow of liquids or gases. They feature quick operation, tight sealing, and minimal pressure loss, making them ideal for use in oil & gas, petrochemical, power generation, water treatment, marine, and food processing industries. Available in various designs such as floating, trunnion-mounted, V-type, three-piece, and top-entry, our valves ensure smooth operation, excellent sealing performance, and long service life even in demanding industrial environments.

Key Features & Advantages
• Ultra-low flow resistance: Full-bore design with Cv values close to straight pipe flow.
