8 Features of Soft Sealing Butterfly Valves

Soft sealing butterfly valve applies to 100 degrees below the hot water and cold water system. If the system requires a higher temperature, a metal sealed butterfly valve is available.

Soft seal butterfly valve sealing ring the maximum use temperature: nitrile rubber NBR is less than or equal to 80 DEG C, three yuan EPDM less than or equal to 120 DEG C, PTFE is not higher than 150 DEG PTFE.

What is the maximum temperature in the acid base medium?

1 chloroprene rubber: nitric acid (10%) 29 DEG C; citric acid 29 DEG C; sodium hydroxide 93 DEG C.

2 butyl rubber: sulfuric acid (50%) 66 DEG C; nitric acid (10%) 40 DEG C; sodium hydroxide 85 DEG C.

3, F4: sulfuric acid (0-100%) 180 degrees; nitric acid (0-100%) 180 degrees; sodium hydroxide 180 degrees

8 characteristics of soft sealing butterfly valve：

1, compact, easy disassembly and maintenance, and can be installed at any location.

2. The structure is simple and compact, the operation torque is small, and the 90 degree rotation is fast.

3, flow characteristics tend to line, good regulation performance.

4, the butterfly plate and stem connection use no pin structure, to overcome the possible leakage point.

5, sealing parts can be replaced, and sealed reliable, to achieve two-way seal.

6, butterfly plate can be sprayed coating according to user requirements, such as nylon.

7, the valve can be designed to flange connection and clamp connection.

8, drive mode can choose manual, electric or pneumatic.
