Pneumatic Diaphragm Valve

Pneumatic Diaphragm Valve

Currently, chemical diaphragm pumps (including imported brands) widely used in the market have common problems such as cavity corrosion, short diaphragm life, high maintenance costs, long maintenance cycles, etc. The customer's factory process improvements have changed greatly, and the opinions on improvement are inconsistent with Suggestions cannot be responded to and resolved quickly. In response to various current situations, the Korida technical team made a series of optimizations and improvements based on investigating the current problems of similar equipment.

Material nameAbbreviationGeneral chemical propertiesMaximum operating temperature
long timeshort
Polyvinyl chloridePVCIt can withstand the corrosion of most "acids", "alkalis" and "salts" from low to high concentrations, but it is not resistant to the corrosion of "aromatic hydrocarbons", "ketones", "ethers" and "chlorinated carbon hydrocarbons".55℃60℃
Chlorinated polyvinyl chlorideCPVCThe chemical corrosion resistance is similar to PVC, but the temperature resistance is better than PVC.95℃110℃
PolypropylenePPThe chemical resistance is very good, and the resistance to general acids is good, but it is less resistant to a mixture of two different acids, such as: nitric acid + sulfuric acid or sulfuric acid + hydrofluoric acid. For general organic solvents.90℃110℃
Polyvinyl difluoridePVDFIt has good chemical resistance and will only be corroded by "oleum, sulfur trioxide, strong alkali amines, ketones", etc.140℃150℃
Polytetrafluoroethylene (Teflon)PTFEIt is almost not corroded by any chemicals, and will only be corroded by a few chemicals at high temperatures.250℃300℃
Fluorine rubber (copolymer of fluorinated ethylene and hexafluorinated propylene) VITONFPMIt has good weather resistance, ozone resistance, oil resistance, heat resistance and chemical resistance. It is self-extinguishing rubber, but its cold resistance is not good (-45℃ embrittlement point).200℃200℃
Ethylene propylene rubberEPDMIt has excellent weather resistance, ozone resistance, chemical resistance, good oil resistance, and is a self-extinguishing rubber. It has poor low temperature resistance and is not resistant to aromatic hydrocarbons.90℃120℃
Butadiene nitrile rubberNBRThe main performance is "good oil resistance", good heat resistance, long-term use at 120°C, poor cold resistance, and poor water resistance.120℃120℃
