PVDF diaphragm valve features as follows:

The prominent feature is that the diaphragm separates the lower valve body cavity from the upper valve cover cavity, so that parts such as the valve stem and valve disc above the diaphragm are not corroded by the medium, eliminating the need for packing sealing structure, and no medium leakage. The diaphragm made of rubber or plastic soft sealing material has good sealing performance. As the diaphragm is a vulnerable part, it should be replaced regularly according to the characteristics of the medium. Due to the limitation of diaphragm materials, diaphragm valves are suitable for occasions with low pressure and relatively low temperature. PVDF diaphragm valve can be divided into six types according to the structural form: roof type, straight-through type, globe type, straight-through type, gate type and right angle type; the connection form is usually flange connection; according to the driving mode, it can be divided into manual, electric and pneumatic three types, of which pneumatic drive can be divided into normally open, normally closed and reciprocating three types. It is generally not suitable for use in pipelines with temperatures above 60 degrees and transporting organic solvents and strong oxidizing media, nor is it suitable for use in pipelines with high pressures.

G41F-10F PVDF diaphragm valve detailed description

Scope of application and structural features: Suitable for the transportation and shut-off of corrosive media, flow regulation, the temperature range is -14°C to 100°C, -40°C to 140°C depending on the material. The flow components are assembled with PVDF injection-molded parts, which have excellent corrosion resistance, convenient operation, light weight, and can replace stainless steel valves. The sealing film is made of F46 or PFA, with a folding resistance of ≥1200 times, and corrosion resistance comparable to F4. It adopts a screw lifting structure, with large opening and closing torque and good stability.

Installation and use of PVDF diaphragm valve: When connecting the two end flanges with the pipeline, tighten the bolts evenly to prevent flange deformation and leakage. Turn the handle clockwise to close and counterclockwise to open. The opening degree can be judged according to the position of the indicator.
