Description

Flanged Centric type Butterfly Valve is usually used water supply and drainage, gas pipeline for the temperature ≤80℃, nominal pressure ≤ 1.6Mpa to regulate the flow and cut off the fluid role.   

Range:DN50-DN1200

Connection type--Flange

Working pressure:PN10/PN16

Temperature:-10-80℃

Fusion bonded epoxy coating

Operating

The valve opening and closing part is a disc - shaped butterfly plate, the disc is rotating around its own axis to achieve opening and closing or regulating effect.     

Drive mode: manual, pneumatic, electric.

Features

1. Long service life with reliable seal and without frequent maintenance.

2. Pressure Loss

Too much pressure loss will bring increased cost of correlative energy. Butterfly valve have flow characteristics three times better than globe valve, and about 75% of a same size gate valve.

3. Multi-Function

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

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.

7. Maintenance

Properly installed butterfly valves are self-cleaning and are less susceptible to failure due to trash material in pipe.
