Imported Pneumatic Rubber-lined Butterfly Valves (Imported Pneumatic Desulfurization Butterfly Valves, Imported Pneumatic Wafer Butterfly Valves, Imported Pneumatic Signal Butterfly Valves)

Brand: German WoldWODE

Imported pneumatic rubber-lined butterfly valves (pneumatic rubber environmental protection anticorrosive butterfly valves) refer to the process of vulcanizing rubber with the valve body of the butterfly valve at high temperature. Generally, they are divided into flanged and clamped types based on the connection method, and different sealing structures with varying performance can be selected according to different working conditions (full rubber-lined butterfly valves, semi-rubber-lined butterfly valves) to ensure normal operation of the pneumatic rubber-lined butterfly valves in various application scenarios. Pneumatic rubber-lined butterfly valves not only have features such as anticorrosion, wear resistance, non-toxicity, and anti-mold, but also possess excellent sealing performance. With the application of chemically resistant synthetic rubber in butterfly valves, The demand for rubber-lined pneumatic butterfly valves has been on the rise continuously.

Imported pneumatic rubber-lined butterfly valves application range:

Lined pneumatic butterfly valves are suitable for conveying liquids and gases (including steam) in various types of industrial pipelines, as well as for use in conditions involving weakly corrosive fluid media, for on/off two-position control or adjustment of medium flow rate. Operating temperature generally does not exceed180°C, Nominal Pressure ≤1.6MPaWidely used in food, pharmaceutical, chemical, petroleum, power, light industry, textile, papermaking, and other fields.

Imported pneumatic lined butterfly valve features:

1The use of rubber-lined, non-rod design ensures complete isolation between the medium and metal, enhancing the product's reliability.

2Sealing surface has excellent wear resistance.(Rubber's wear resistance is seven times that of copper.)。

3Can be installed at any location, with convenient maintenance.

4Sealings are replaceable and offer reliable sealing performance, achieving bidirectional zero-leakage sealing.

5Rubber materials are non-toxic and resistant to bacteria and mold, with prices one-third of stainless steel valves.
