Features: _x000D_ This check valve allow the liquid or air to flow in only one direction, thus preventing backward flow. _x000D_ Features good high temperature resistance and corrosion resistance _x000D_ Widely used in many industry applications including fuel pumps, engines, household appliances, medical devices, agriculture equipment, beverage machinery, ink supply systems, etc. _x000D_ The material for this check value can endure fuel/oil, acid, alkaline solutions. _x000D_ This one way check valve is convenient for replacing the broken one_x000D_ _x000D_ _x000D_ _x000D_ Specification: _x000D_ Body material: PA66 _x000D_ Sealing material: VITON _x000D_ Spring material:SUS316L_x000D_ _x000D_ Connection form: quick install _x000D_ Type: 1/8", 3/16",1/4",5/16"(Optional) _x000D_ Structure: one-way valve _x000D_ Applicable medium: oil _x000D_ Form: spring type _x000D_ Pressure environment: normal pressure _x000D_ Flow direction: one-way _x000D_ Driving mode: servo _x000D_ Working temperature: high temperature _x000D_ Spring one-way valve opening pressure :1~2Kpa _x000D_ Weight: Approx.4g~5g/0.1oz~0.2oz _x000D_ _x000D_ Body material:_x000D_ _x000D_ 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. _x000D_ Sealing material: _x000D_ _x000D_ 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 _x000D_ _x000D_ Spring material: _x000D_ 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 _x000D_ _x000D_ _x000D_ Package list: _x000D_ 1 x Inline Check Valve _x000D_
