Umbrella Valve also knowns as Umbrella Valve Seals, Umbrella Check Valve, Rubber Umbrella Valve and Liquid Silicone Valves, is mainly made from high-tensile solid silicone (HTV) or liquid silicone rubber (LSR) materials, also made from other rubber materials like Neoprene, EPDM, Fluorosilicone, Nitriles etc. The production of silicone rubber umbrella valves involves a striking balance between efficiency and quality. To achieve this balance, different manufacturing processes must be considered and compared to determine which process better matches the product's particular needs.
