APPLICATIONS • Water supply • Drinking water • Waste water treatment plants
Epoxy paiting suitable for drinking water applications.
The double flanged butterfly valves with eccentric disc are applied in the pipelines as shut-off device and as regulation valves, thanks to the gear box that can stop the disc in many intermediate positions. These double flanged butterfly valves with regular face to face DIN 3202 F4 allows the perfect exchange with regular flat body gate valves, whenever needed. The double flanged butterfly valves can stand both directions of fluid, gasket seals are on the disc and can be replaced without dismantling the valves from the pipeline. The double flanged butterfly valves with double eccentric disc can be installed in drinking water plants, being painted with epoxy powder. The gear box is suitable for electric actuator and installation is easy, taking off the handwheel from the gear box itself.
A Butterfly valve is a quarter-turn rotary motion valve, that is used to stop, regulate, and start the flow. Butterfly valves are a quick open type. A 90° rotation of the handle can completely close or open the valve. Normally, they are used in systems where a positive shut-off is not required. In this article, you will learn about following types of Valve.
Large Butterfly valves are usually equipped with gearbox type actuator, where the handwheel is connected to the stem via a gearbox. This will reduce the force but at the same time reduce the speed of the operation. This type of valve should be installed in the open position. If the valve is closed during installation, the rubber seat will wedge against the valve disc and make it difficult to open.

Types of Butterfly Valves Based on Body Construction
Based on the type of ends of the body butterfly valves are available in following types.
Both Flanged Ends
Wafer Type Ends
Lug Type Ends
Butt Welded Types Ends
Water Type
The wafer body is placed between pipe flanges, and the flange bolts surround the valve body. A wafer type butterfly valve is easy to installed but it cannot be used as an isolation valve.
Seat Types
Butterfly valves can be metal-to-metal seated, soft seated, or with a fully lined body and disc. The first image is of a soft seated fully lined body and disc valve. Second, is a soft seat with metal disk and the third is metal to metal seat type valve.
Triple Offset Butterfly Valve
In Triple Offset design the third offset created by the geometry design of the seating surface.
The seat is machined into an offset conical profile resulting in a right-angled cone. You can see this in the
third image with small enlargement of seating angle.
This ensures frictionless stroking throughout it's operating cycle. Contact is only made at the final point of
closure with the 90° angle acting as a mechanical stop; the Metal seated valve uses triple offset design.
Flanged Type
In this types, the body has flanged that match with pipe flange dimension.
