Custom Rubber Flow Control Valves & Check Valves

Rubber flow control valves, check valves, and one-way flappers are critical components in unidirectional flow applications. RD Rubber Technology Corporation is a custom manufacturer of custom-molded thermoset elastomer components for industries, including the defense, aerospace, and space exploration. Learn more about our custom rubber flappers, including their material composition, our manufacturing capabilities, and our quality certifications for peace of mind in critical-to-function applications.

Engineered-Quality Flow Control & Check Valves for Precise Pressure Regulation

In unidirectional flow applications, the integrity of a seal determines the reliability of the entire system. We engineer custom-molded rubber flow valves to meet exact customer specifications for pressure regulation and fluid management. These components are essential for critical-to-function applications that rely on leak prevention and precise response times.

Our engineered-quality rubber check valves maintain their structural profile under repeated cyclic loading, preventing the deformation that leads to backflow. We offer the technical depth necessary to produce these high-performance parts for:

  • Aerospace systems. Managing fuel and air pressure in the cockpit and engine environments.
  • Defense hardware. Supporting fluid management in tactical vehicles and equipment.
  • Space exploration. Maintaining reliable pressure regulation and liquid/gas management in extreme vacuum and thermal environments.

Material Selection for Thermal Stability in Liquid and Gas Handling

The performance of a check valve depends heavily on the chemical and thermal properties of the selected elastomer. We can work with a wide selection of materials to deliver custom-molded rubber valves that remain stable in demanding environments. Our team evaluates variables like operating temperature conditions and fluid exposure to identify the optimal material for your application.

We utilize several specialized elastomers to maintain thermal stability:

  • Viton™ and Fluoroelastomer (FKM). These materials resist high temperatures and aggressive chemicals, making them ideal for fuel and oil systems.
  • Fluorosilicone (FVMQ). This elastomer maintains its properties amid extreme temperature swings and resists degradation from contact with oils and solvents.
  • EPDM and Nitrile (Buna-N). These are used for standard liquid and gas handling where ozone or oil resistance is required.
  • Silicone and Liquid Silicone. These materials provide excellent thermal stability and biocompatibility for medical and food processing applications.

We maintain extensive material traceability for every project. This documentation verifies that the raw materials used in your custom rubber flappers meet the specified Mil-Spec or ASTM standards.

Quality Certification for Aerospace and Defense Component Integration

RD Rubber follows a systematic approach to quality assurance for every custom-molded rubber solution we produce in the aerospace, defense, and space exploration sectors. We utilize specialized equipment, such as our FaroArm CMM, to inspect and verify that every rubber flow valve meets the required dimensional tolerances.

Our facility maintains the following certifications and registrations to support reliable sourcing:
