JT.1133 Black Inflation Silicone Umbrella Valve
The umbrella valve is a one-way, automatic seal that allows fluid to flow in one direction and prevents fluid from flowing back in the opposite direction. When the pressure in the direction of the umbrella is greater than the pressure in the direction of the umbrella bottom, the umbrella surface is pressurized to form a seal, and when the pressure in the direction of the umbrella bottom is greater than the opening pressure of the umbrella surface, the fluid passes.DT.0166 Red Silicone Rubber Umbrella Gas Air Release Relief One Way Non Return Rubber Umbrella Valve
The umbrella valve is a one-way, automatic seal that allows fluid to flow in one direction and prevents fluid from flowing back in the opposite direction. When the pressure in the direction of the umbrella is greater than the pressure in the direction of the umbrella bottom, the umbrella surface is pressurized to form a seal, and when the pressure in the direction of the umbrella bottom is greater than the opening pressure of the umbrella surface, the fluid passes.DT.0080 Black Food Grade Silicone Rubber Non Return 1 2 One Way Air Release Check Valve Core Valve Umbrella Valve

Valve Materials Overview
At ValveKingdom, we provide a wide selection of materials to ensure the best fit for your application in terms of function, safety, and cost. Whether used in medical devices, automotive systems, pumps, or fluid handling solutions, our precision valves are crafted from materials that meet global quality and regulatory standards.
Elastomer Materials
Elastomers are essential in many precision molding and sealing applications due to their outstanding flexibility, resilience, and resistance to extreme environments. Each elastomer type provides unique benefits—from temperature and chemical resistance to varying hardness and elasticity—allowing for optimized performance across diverse industries. At ValveKingdom, we offer a wide selection of high-quality elastomer compounds to meet functional, regulatory, and cost requirements, ensuring your products perform reliably in their intended applications.
Silicone
Silicone is a widely used, cost-effective material known for its flexibility and biocompatibility. All our silicones are medical-grade (USP Class VI, ISO10993) and food-grade (EU1935-2004, FDA 21 CFR), with excellent temperature resistance from -40°C to +200°C. Available in multiple hardness levels from Shore A 20 to 80, silicone offers outstanding versatility for both medical and consumer applications.
EPDM
Our EPDM materials are peroxide-cured and precisely formulated for valve molding. They exhibit strong resistance to steam, polar substances, ketones, diluted acids, and alkalis. With certifications under EU1935-2004 and FDA 21 CFR, EPDM is ideal for sanitary and fluid systems. It performs reliably within a temperature range of -40°C to +120°C.
Fluorosilicone (FVMQ)
Fluorosilicone combines the temperature stability of silicone with the chemical resistance of fluorocarbon. It is highly resistant to fuels, oils, and hydrocarbons, making it an excellent choice for automotive and industrial applications exposed to aggressive environments.
Fluorocarbon (FKM)
Fluorocarbon elastomers provide exceptional resistance to strong chemicals, solvents, and high temperatures. They are widely used in harsh environments such as fuel systems and chemical processing, where long-term sealing integrity is essential.
Plastics
Our range of engineered plastics includes Co-Polyester, Polycarbonate, Glass-Filled PPE, and PEEK. These materials meet medical, food, and automotive standards, offering high strength, chemical resistance, and stability for complex valve assemblies.
If you have specific material requirements or challenges, our Application and Sales Engineers are ready to help. With extensive experience in functional design and problem-solving, ValveKingdom delivers material solutions tailored to your exact needs.
