What is the Difference Between EPDM and PTFE Valves?
Industrial flow control solution providers are in everyone’s eye and were more so in yesteryears. Production of flow control equipments is concentrated in few countries. Benefiting from favorable policies and subsidies, China is holding steady at lead position. As a result, When it comes to industrial flow control solutions—particularly in challenging applications such as shipbuilding, water treatment, and chemical processing—it is important to know the difference between the linings of EPDM vs PTFE valves. Both of these materials are very commonly found in butterfly valves, however their characteristics are unique and they differ considerably including chemical compatibility and life span.
EPDM rubber (Ethylene Propylene Diene Monomer) is a synthetic rubber that has excellent water resistance, steam resistance, and resistance to polar solvents and weathering. It is the optimal choice of lining for Epdm Lined Butterfly Valves which are widely used in drinking-water systems, hvac applications and in marine conditions. Products like Marine Butterfly Valve, Marine Butterfly Valves, Duplex Butterfly Valves most of the times use EPDM seats because they are more flexible, have higher sealing capabilities and are more cost effective.
For Bulk Buying and Wholesale Trading, you can of course count on us for Top quality Wholesale Epdm Lined Butterfly Valves, Wholesale Butterfly Valve Epdm, and Wholesale Lug Type Butterfly Valve with EPDM Linings is the best choice for you. In addition, Butterfly Valve Epdm Manufacturers commonly equip EPDM seats to gear operators, presenting the possibilities of Gear type butterfly valve, Wholesale Gear Type Butterfly Valve and Wholesale Gear Operated Wafer Type Butterfly Valve in terms of higher torque control.
Meanwhile, PTFE (Polytetrafluoroethylene) has better chemical resistance under wide pH value, so it is suitable for aggressive media like acids, alkalis and solvents. A Wholesale Ptfe Butterfly Valve is generally designated where EPDM would have worn out. Although the exceptional non-stick properties and high-temperature stability of PTFE, it’s less flexible than EPDM, which could lead to sealing failure at very low pressure. Still, in chemical plants and pharmaceuticals systems, the utility of a PTFE Lined Ball Valve becomes essential.
In addition to materials, design of the valve is important too. Butterfly Valve Gear Type actuators (Precision and Safety for Large Diameter applications) and Wholesale Wafer Butterfly Valve, Wholesale Wafer Type Butterfly Valve and Wholesale Grooved Type Butterfly Valve options for various installation standards.
For pipeline defense, check valves such as Wholesale Silent Check Valve, Dual Plate Check Valve Flange Type, Wholesale Dual Plate Wafer Check Valve and Single Disc Wafer Check Valve efficiently stop backflow. Many buyers also keep Soft Seated Check Valve Suppliers products, including Wholesale Disk Check Valve and Single Disc Check Valve with butterfly valves for system solutions.
