They are open and close very quickly when actuated pneumatically. The disc is lighter than a ball, and the valves require less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.1. Turning on/off easily and rapidly with less force. Having less fluid resistance and can be operated frequently.2. Simple structure, small size and short face to face dimension, which suitable for large diameter valves.3. It can be used for transmitting mud, fewer liquids are stored at apertures of pipe.4. Long service life. Standing the test of tens of thousands of opening/closing operations.5. Butterfly valves have excellent regulation performance.6. Small torque. The pressure on discs at the two sides of the spindle is almost equal, causing contrary torque. Thereby, the valves can be opened with less force.7. Sealing face is generally med of rubber or plastic. So the butterfly valves can be with good sealing under low pressure. MOQWe do not have any MOQ for this valve, 1 set order is also can be accepted.DeliveryIt depends on the order quantity, but not more than 35-40days after received payment By seaLCL shipment Container shipmentBy airBy air cargo or courier for samplePayment way30% deposit, the balance will be paid before loading. Hydraulic testingWe promise 100% hydraulic testing before exporting, with a testing machine and testing bowl(for big size).Body testing: 1.5* design pressureSealing testing 1.1* design pressureWe can provide a 12-month warranty after the shipping date.Packing wayPlywood case in exporting standard, bubble plastic packing insideFor large size, we will use steel pallet with bubble plastic packing outsideOur Overseas Exhibition Our website: davanflowtek.en.made-in-china.com/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
