One Way Check Valve, also known as Flow Control Valve, Pressure Relief Valve, which is a device that only allows the flow of fluids in one direction. They have two ports, one as an inlet for the media and one as the output for the media. Since they only allow media flow in one direction, they are co

Fluorosilicone VS. Silicone for Gasket Seal Valve: Fluorosilicone (FVMQ) is an elastomer which likes silicone (VMQ) offering excellent extreme temperature stability along with greater resistant to fuel, oil, petroleum based fluid, non-polar solvents, acid and alkaline chemicals similar to fluorocarbon rubber (FKM, FPM, Viton). Fluorosilicone gasket, seal, o-ring and check valve are widely used.
