Pneumatic diaphragm valve, normally open G6K41J, normally closed G6B41J-6,

Purpose and main performance specifications

1. 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.

2. Recommended usage range for various visual wrapping materials:

Visual wrapping material (code)	Applicable temperature	Applicable media
Hard rubber (NR)	-10 ℃～85 ℃	Hydrochloric acid, fluorosilicic acid, formic acid and 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, etc., in addition to strong oxidants such as sulfuric acid, chromic acid, concentrated sulfuric acid and hydrogen peroxide, which have organic solvents.
Soft rubber (BR)	-10 ℃～85 ℃ ]	Has good 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 ℃～120 ℃	Corrosion resistance and wear resistance. Capable of withstanding a wide range of organic acids, bases, hydroxides, inorganic salts, inorganic acid elemental gases, alcohols, aldehydes, ethers, ketones, esters, etc.
Chloroprene rubber	（CR）-10 ℃～120 ℃	Animal oil, vegetable oil, inorganic lubricating oil, and corrosive mud with a wide range of pH values have good wear resistance.
Cast iron without visual wrapping	-40 ℃～100 ℃	Non corrosive medium
