Double eccentric butterfly used pneumatic valve characteristics description < / div >

adjustment in the pneumatic valve has a linear type, double eccentric, triple eccentric, let's focus on the using characteristics of double eccentric butterfly pneumatic valve, pneumatic valve due to the adjustment using range is wide, small make up first to introduce the commonly used small butterfly pneumatic valve's basic common sense, butterfly on the pneumatic valve is mainly used in fluid pipe used as adjustment and the river closure, mainly is suitable for the construction industry, chemical industry, water drainage, sewage, food, medicine, water and electricity, shipping and so on, we will recommend different requirements according to the special working condition of medium pneumatic valve pneumatic butterfly valve body material, such as seawater medium: recommended pneumatic valve pneumatic butterfly body choose stainless steel material, mainly for switch closure of sea water and flow control, the working condition of recommend stainless steel material of main consideration will have certain corrosive seawater. Oxygen medium: the medium before buying pneumatic valves must be clear, because we will be used during manufacturing pneumatic valve adjustment strictly banned oil processing, the working condition of medium pneumatic valve is recommended high-quality stainless steel. Corrosive medium, the medium must choose anti-corrosion materials, we recommend the use of stainless steel and ptfe ( PTFE） Devastating, due to the corrosive medium is bigger, the requirement of pneumatic valve material quality control pneumatic valve must be used.

double eccentric butterfly pneumatic valve features: 1, the integral casting, double flanged links. 2, double eccentric structure design, long service life, good adjusting flow characteristic. 3, spherical sealing structure, two-way sealing butterfly pneumatic valve zero leakage. 4, butterfly plate adopts streamline design, small flow resistance. 5, high-strength one-piece pneumatic valve stem, end of standardized design, so the design of the actuator is easy to replace. 6, can be more HuanXing standard sealing ring, use rise is advantageous for the replacement of maintenance. 7, surface coating technology of epoxy resin, meet drinking water standards. 8, the standard connection size manufacturing, in line with the national standard, American standard, such as national standards.
double eccentric butterfly used pneumatic valve installation instructions: use correct installation can prolong the service life of pneumatic valve adjustment, we recommend that butterfly pneumatic valve can be installed in horizontal or vertical installed on the pipeline, in any case when installation, please ensure that the pneumatic valve stem and the ground level, such as working condition does not allow, it is recommended that the pneumatic valve rod and ground slightly skewed Angle ( Not easy to excessive deflection) , because such installation can prevent fluid particles in direct contact with the pneumatic valve rod bearing, or too much will to pneumatic valve has a certain degree of loss, in addition, for large diameter butterfly pneumatic valve, pneumatic valve plate shall be borne by the butterfly pneumatic valve bearings, the weight of the skewed too much easy to cause some wear and tear, in order to achieve the best performance and service life, please according to the manufacturer to the installation of a butterfly pneumatic valve is recommended.
