Features: Medical grade material, safe and nontoxic Resistance to high temperature of 150 degrees, ozone resistance, and corrosion resistance High mechanical strength, wear resistance and durability It has enough pressure bearing capacity and rigidity to meet the actual use requirement within its proper range Widely used in water treatment, air purification, automotive parts, machinery industry, medical equipment, household appliances and other fields This one way check valve is convenient for replacing the broken one Specification: Shell material: PP Sealing material :VITON,SILICONE(Optional) Type(Optional): PP shell/SILICONE Sealing material, PP shell/VITON Sealing material Size:3/8" 10mm Connection form: quick install Structure: diaphragm one-way valve Applicable media: all kinds of highly corrosive chemical media Form: diaphragm type Pressure environment: normal pressure Standard: British standard Direction of flow: one-way Working temperature: normal temperature Diaphragm one-way valve opening pressure < 0.5kpa (0.005kg water pressure) Weight: Approx.3g/0.1oz Material 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 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 Silicone 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 1,Medical grade material, safe and nontoxic 2,Resistance to high temperature of 150 degrees, ozone resistance, and corrosion resistance 3,It has enough pressure bearing capacity and rigidity to meet the actual use requirement within its proper range 4,High mechanical strength, wear resistance and durability 5,Widely used in water treatment, air purification, automotive parts, machinery industry, medical equipment, household appliances and other fields
