Features 1、This check valve allow the liquid or air to flow in only one direction, thus preventing backward flow. 2、Features good high temperature resistance and corrosion resistance 3、Widely used in many industry applications including fuel pumps, engines, household appliances, medical devices, agriculture equipment, beverage machinery, ink supply systems, etc. 4、 The material for this check value can endure fuel/oil, acid, alkaline solutions. 5、This one way check valve is convenient for replacing the broken one Specification Features: This check valve allow the liquid or air to flow in only one direction, thus preventing backward flow. Features good high temperature resistance and corrosion resistance Widely used in many industry applications including fuel pumps, engines, household appliances, medical devices, agriculture equipment, beverage machinery, ink supply systems, etc. The material for this check value can endure fuel/oil, acid, alkaline solutions. This one way check valve is convenient for replacing the broken one Specification: Body material: PA66 Sealing material: VITON Spring material:SUS316L Connection form: quick install Structure: one-way valve Applicable medium: oil Form: spring type Pressure environment: normal pressure Flow direction: one-way Driving mode: servo Working temperature: high temperature Spring one-way valve opening pressure :1~2Kpa Weight: Approx.4g~5g/0.1oz~0.2oz Body material: Nylon 66 (PA66) : translucent or opaque milk white crystalline polymer, malleable, melting point 252℃. Brittle temperature 30℃. The thermal decomposition temperature greater than 350℃. Continuous heat 80-120℃. It is resistant to acid, alkali, most inorganic salt aqueous solutions, halogenated alkanes, hydrocarbons, esters, ketones and other corrosion, but soluble in phenol, formic acid and other polar solvents. Excellent wear resistance, self - lubricating, high mechanical strength. Sealing material: Fluorinated rubber (VITON) : with high temperature resistance, oil resistance and resistance to a variety of chemical corrosion characteristics, fluorinated rubber has a high degree of chemical stability, is the elastomer in the medium resistance of the best one. Fluorine rubber has excellent anti - aging and ozone resistance. Fluorine rubber has a high solubility to gas, but a low diffusion speed, so it has a low air permeability Spring material: SUS316L stainless steel: SUS316L stainless steel is an acid resistant, corrosion resistant alloy material, it has high temperature resistance, easy to process, high strength and so on Package list: 1 x Inline Check Valve Package List
