DN100(4 Inch) Double Flange Butterfly Valve with Worm Gear

Double flange butterfly valve, has flanges welded to its body – one at the upstream end of the valve and the other at the downstream end of the valve. This type of butterfly valve, used to regulation and flow sectioning in water supply facilities, plumbing, irrigation, etc, is the most resilient seated valve design which is usually used for dead-end service, It has low head loss due to a hydrodynamic design of the disc, it is 100% water tight and need no gaskets to be installed.

Double flanged butterfly valve is easier to mount and center, and is also mechanically stronger in construction than lug or wafer design, making it suitable for heavy-duty, large flow-handling scenarios.

3. Multi-Function
   Flange butterfly valve can be used for on/off service and throttling. They are superior in Multi-function as compared to gate valves. Butterfly valve can be widely used in chemical field due to trim options and choice of elastomeric liner.
4. Weight
   Flange butterfly valve have feature of light in weight and small in size, for example, weight and size of a 10” butterfly valve are 1/9 and 1/6 of a 10” gate valve. So, butterfly valve is easy to be installed and saves cost of piping system.
5. Bubble Tight
   Butterfly valve with resilient seat design can be bubble tight as compared to metal seated gate or globe valves.
6. Easy of operation
   Butterfly valve offer 90-degree open to close.
