This series of diaphragm valves can be used as an opening and closing mechanism to control the flow of different fluid media in pipelines at different temperatures according to different coating materials.

Recommended application range of various coating materials for normally closed pneumatic lined diaphragm valves:

Coating Material (Code) Applicable Temperature Applicable Medium

Hard rubber (NR) -10 ° C to 85 ° C except for strong oxidants (such as sulfuric acid, chromic acid, concentrated sulfuric acid, and hydrogen peroxide, which have organic solvents), hydrochloric acid, fluorosilicic acid, formic acid, phenolic acid, hydrochloric acid, 30% sulfuric acid, 50% hydrofluoric acid, 80% phosphoric acid, alkali, salt, metal plating solution, sodium hydroxide, potassium hydroxide, neutral salt solution, 10% sodium hypochlorite, wet chlorine gas, ammonia water, most alcohols, organic acids, and aldehydes.

Soft rubber (BR) with a temperature range of 10 ° C to 85 ° C has excellent wear resistance. Mainly used for sulfuric acid below 50%, sodium hydroxide, potassium hydroxide, neutral salt bath solutions and ammonia solutions, cement, clay, coal slag ash, granular fertilizers and solid fluids with strong abrasion resistance, various concentrations of viscous liquids, etc.

Butyl rubber (IIR) -10 ° C to 120 ° C is corrosion-resistant and wear-resistant. Capable of withstanding a wide range of organic acids, bases, hydroxides, inorganic salts, inorganic acid elemental gases, alcohols, aldehydes, ethers, ketones, esters, etc.

Chlorinated rubber (CR) -10 ° C to 120 ° C is a corrosive mud with a wide range of animal oil, vegetable oil, inorganic lubricating oil, and pH value changes, and has good wear resistance.

Cast iron without coating -40 ° C to 100 ° C non corrosive medium
