JT.1244 green gas release pressure relief duckbill valve
JT.1244 duckbill valve is a one-way valve used to control the flow of fluids and gases. It is usually made of a flexible elastomer such as rubber or silicone, and is designed in the shape of a flattened cone, with a slit at the top. When fluid or gas flows through the valve in the correct direction, the pressure forces the slit closed, preventing backflow. When the pressure is reversed, the valve opens, allowing the fluid or gas to flow through in the opposite direction. Duckbill valves are commonly used in medical devices, industrial applications, and in automotive applications where they are used to prevent fuel tank overflow during refueling.9.5mm JT.1158 Red EPDM Rubber One Way Check Valve Duckbill Valve

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.Red Rubber Silicone Seal Umbrella Valve
Umbrella valve is a one-way valve that controls the flow of liquid or gas through a system. It is typically made up of a flexible elastomer material such as silicone or rubber, which allows for the valve to open and close as fluid pressure changes. The valve is called an "umbrella valve" because its design resembles an open umbrella with a central stem and a flexible top that seals against the valve seat. Umbrella valves are commonly used in medical devices, such as respiratory equipment, catheters, and drainage tubes, as well as in automotive and industrial applications.
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.
