Features:Medical grade material, safe and nontoxic Resistance to high temperature of 150 degrees, ozone resistance, and corrosion resistanceHigh mechanical strength, wear resistance and durabilityIt has enough pressure bearing capacity and rigidity to meet the actual use requirement within its proper rangeWidely used in water treatment, air purification, automotive parts, machinery industry, medical equipment, household appliances and other fieldsThis one way check valve is convenient for replacing the broken oneSpecification:Shell material: PPSealing material :VITON,SILICONE(Optional)Type(Optional): PP shell or SILICONE Sealing material, PP shell or VITON Sealing materialSize:3 or 8" 10mmConnection form: quick installStructure: diaphragm one-way valveApplicable media: all kinds of highly corrosive chemical mediaForm: diaphragm typePressure environment: normal pressureStandard: British standardDirection of flow: one-wayWorking temperature: normal temperatureDiaphragm one-way valve opening pressure andlt 0.5kpa (0.005kg water pressure)Weight: Approx.3g or 0.1ozMaterial of valve body:Polypropylene (PP) : a semi-crystalline material that is hard and has a higher melting point. PP material with low thermal deformation temperature (100), low transparency and gloss, low rigidity, but have stronger impact strength, impact strength of PP increased with the increase of ethylene content increased. PP vicat softening temperature is 150. Due to its high crystallinity, the material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking of PP.Sealing materialFluorinated 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 permeabilitySilicone rubber(SILICONE): it has the characteristics that are difficult to be replaced by other similar materials: good adsorption performance, good thermal stability, stable chemical performance, high mechanical strength, etc.Package list:1 x Inline Check Valve
