Resilient butterfly valve can be used in these occasions!

Resilient butterfly valve, its driving mode is common handle, turbine, pneumatic, electric four. The connection form has two common types: wafer and flange. resilient butterfly valve is named because of its sealing surface material.

The sealing surface material of the resilienting butterfly valve is commonly EPDM, NBR, PTFE, these three kinds of sealing material to adapt to the medium is not the same, the use of the corresponding butterfly valve is not the same.

EPDM, applicable temperature -40~120℃, applicable media including water, steam and other weak acid alkaline medium, its advantages are ozone resistance, heat resistance, aging resistance, ethylene propylene diene rubber as the sealing surface of the resilient butterfly valve is widely used in construction, power generation, water conservancy and other fields.

NBR, applicable temperature -30~90℃, applicable medium such as water, oil, waste liquid and so on. Its advantages are good oil resistance, wear and heat resistance, strong adhesion; Disadvantages are low temperature resistance, poor ozone resistance, poor insulation performance, slightly lower elasticity. The resilienting butterfly valve with nitrile rubber as the sealing surface is used in lubricating oil, oil, aviation, automobile, printing, textile and machinery manufacturing.

PTFE ene, suitable for temperature -196~200℃, suitable medium is some corrosive liquid, its advantages are heat resistance, cold resistance, resistance to general chemical solvents and almost all liquids. With PTFE as the sealing surface of the resilient butterfly valve is widely used in chemical industry, petrochemical, oil refining, chemical fiber, non-ferrous smelting and other fields.

resilient butterfly valve is usually characterized by small size, light weight, good sealing performance, can do zero leakage. resilient butterfly valve can be used in different occasions, we need to choose which kind of sealing material according to their own working conditions to use resilient butterfly valve.
