Why Fluorocarbon Rubber (FKM, FPM, Viton), Fluorosilicone (FVMQ, FSR) are chosen to make check valve?Compared with common silicone rubber material, FKM & FVMQ has excellent oil resistant, organic solvents resistance and petroleum based fluid resistance. FKM & FVMQ umbrella valve is fluoro elastomer valve that has a mushroom shape. Fluorosilicone umbrella seal valve can be used as sealing element to prevent backflow for one-way valves, check valves, in vent valves or pressure relief valves and in metering valves.

FKM & FVMQ Check Valve Design Guide
FPM & FKM valve seal usually has undercut design structure, which should be made of material with high tensile elastic manuafctured by three-plate mold for avoiding damage when ejected valve from mold.
But FPM & Fluorosilicone (FVMQ) material don't have so excellent high tensile property compared with Silicone Rubber material. When we design the valve, we usually make larger radius around the undercut for helping easier demoulding.

Fluorocarbon Rubber(FPM & Viton) Umbrella Check Valve | Fluorosilicone Rubber(FSR) Mushroom Seal Valve |
High temperature resistant Oil resistant, Flame resistance Chemical products resistance Low temperature propertirs | High-low tempreture resistance Oil & Solvent resistant Petrol resistance Ageing resistance |
In addition, fluorocarbon rubber is the only elastomer that can be used in the fuel medium at -68-230℃.

Outside Surface: EDM process or texture surface for dust proof
Inside Diaphragmatic Ring Edge Surface: Polish or high-polishing for sealing function
FKM & FVMQ Umbrella One Way Valve Manufacturing Process
FKM & FVMQ Check Valve Application:
FPM & FVMQ valve with excellent performace are widely used in automotive, chemical and aerospace industries.
Applications in automotive fuel including fuel alcohol and other fuel mixtures or in engine oil or automatic transmission oil often use fluorosilicone (FVMQ) and fluoroelastomer (FKM) rubber umbrella check valve.
Even prolonged immersion in harsh engine oils, transmission and power steering fluids, and all grades of gasoline and jet fuels, there is little effect on properties for FVMQ umbrella valve.
