In which areas the Soft Sealing Butterfly Valve is used, the influencing factor is the sealing surface material of the Soft Sealing Butterfly Valve.

customized Soft Sealing Butterfly Valve
The common sealing surface materials of Soft Sealing Butterfly Valve include EPDM, NBR, PTFE, and PTFE. These three types of sealing materials are not the same as the medium, and the corresponding butterfly valve is not used in the occasion. the same.
EPDM ethylene propylene rubber, applicable temperature -40~120 ℃, applicable media include water, steam and other weak acid and alkali media, its advantages are ozone resistance, heat resistance, aging resistance, EPDM rubber is the soft sealing surface Sealing Butterfly Valve is currently widely used in construction, power generation, water conservancy and other fields.
NBR nitrile rubber, applicable temperature -30~90℃, applicable media include water, oil, waste liquid, etc. Its advantages are good oil resistance, abrasion and heat resistance, and strong adhesion; the disadvantages are low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. The Soft Sealing Butterfly Valve with nitrile rubber as the sealing surface is used in lubricating oil, motor oil, aviation, automobile, printing, textile and machinery manufacturing and other fields.
PTFE polytetrafluoroethylene, the applicable temperature is -196~200℃, the applicable medium is some corrosive liquids, and its advantages are excellent heat resistance, cold resistance, resistance to general chemical solvents and almost all liquids. The Soft Sealing Butterfly Valve of PTFE is currently widely used in chemical, petrochemical, oil refining, chemical fiber, non-ferrous smelting and other fields.
Soft Sealing Butterfly Valve is usually characterized by small size, light weight, excellent sealing performance, and zero leakage. Understand the advantages of soft sealing and master its shortcomings, you can use Soft Sealing Butterfly Valve reasonably according to your own working conditions, so that it can play its own value to serve us.
