DN100 PN16 Lug Butterfly Valve with Handwheel
Butterfly valves are quarter turn valves ideal for on/off operations as well as modulating flow. This valve is rated for 16 bar non-hazardous fluids and is operated by a hand wheel. Please note that the maximum pressure may deviate based on the medium type so carefully check the datasheet. The nominal diameter is 200 mm (8 inch) and is mounted to your system by an wafer type flange. The Cast iron (GGG40) housing makes it suitable for higher pressure and temperatures then the standard GG25. The GGG40 polyamide coated disc is the standard option The NBR seal allows for a temperature range of 5°C - 85°C.

Material of Main Rarts:
Butterfly valves are similar to ball valves but have more advantages. 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.
We do not have any MOQ for this valve, 1 set order is also can be accepted.
It depends on the order quantity, but not more than 35-40days after received payment
