Tank Bottom Diaphragm Valve

The valve body adopts CNC precision machining ,ensures that the sealing surface of the valve cavity is in accordance with the isolation of the diaphragm, reduces the friction of the diaphragm, and extend the service life of the diaphragm

> The surface of the valve cavity can be polished mechanically  or electrolytically according to customer requirements, the roughness is about 0.25μ

Soft Elastic Material Diaphragm

The diaphragm made of soft elastic material will not react sensitively to those working media contaminated by fiber clusters, solid particles, catalysts, etc. Generally speaking, it will not affect the operation and sealing of the valve. According to the temperature of work or disinfection. And the chemical characteristics of the working medium, you can choose different materials.

FDA Certification

Aseptic Diaphragm Valve Diaphragm is manufactured according to FDA standards.We can also provide other standard certification certificates according to customer requirements.

Material Selection

Due to different types of valves and materials will be selected under different working conditions, before selecting the valve body and diaphragm, the application of each product must be analyzed, especially for the application of chemical medicine and the chemical reaction caused by high temperature. Test the suitability of materials through valid chemical data or expert certification. In order to ensure the safety and long-term effectiveness of the product.

Diaphragm Fixation

The typical method of fixing the diaphragm is screw fixing. Incontrast to the hole fixing, this fixing method distributes the force area to the entire surface of the bolt, which is to prevent the mechanical connection of the diaphragm under the vacuum condition.
