Medical check valve for rubber processing "Umbrella Duckbill"

Medical check valve for rubber processing "Umbrella Duckbill"

High-quality fluid control solutions in precision rubber molding and processing processes.

The "Umbrella Duckbill" from Fujikura Composite is a core component for liquid control, born from the fusion of unique material formulation technology cultivated over many years and micron-level molding precision. It goes beyond the mere function of a "check valve," with a design that maximizes the elasticity and resilience of rubber, fundamentally supporting the "precision" and "reliability" of processing sites. 【Application Scenarios】 - Nano-level thin-walled molding: Achieves extremely thin and uniform wall thickness molding, such as in the umbrella part of the valve. It generates extremely high responsiveness, reacting linearly to minute pressure changes. - Advanced mold and molding design: Utilizes finite element method (FEM) analysis to simulate rubber's compression set and fluid behavior in advance. Establishes shapes that minimize seal degradation due to aging. - Diverse high-performance formulations: Designs optimal rubber formulations in-house, tailored to the usage environment (heat resistance, oil resistance, chemical resistance) using materials such as fluororubber (FKM), EPDM, and medical-grade silicone. Physical properties remain stable even under harsh conditions. 【Benefits of Implementation】 - Reduction of reagent loss due to backflow prevention - Maintenance of reagent quality by preventing external contamination - Improved safety

Medical check valve for pharmaceutical and cosmetic manufacturing.

Medical check valve for pharmaceutical and cosmetic manufacturing.

High-precision filling and contamination prevention solutions

In the manufacturing sites of pharmaceuticals and cosmetics, it is essential to deliver high-value liquid agents to containers "without contamination," "without waste," and "accurately." Particularly in the handling of diverse product types and high-viscosity liquids (such as creams and gels), losses due to liquid dripping and cross-contamination pose significant challenges in quality control. Fujikura Composite's precision check valve, the "Umbrella Duckbill," demonstrates extremely high sealing performance with a simple structure, achieving both improved yield and stringent quality assurance. 【Application Scenarios】 - High-precision filling and dispensing - Prevention of liquid dripping and trailing - Backflow prevention for metering pumps - Airless containers and pump components 【Benefits of Implementation】 - Thorough elimination of contamination risks: Made entirely of rubber (such as silicone) without using metal springs, it reduces the risk of metal wear particles contaminating the product to zero. - Excellent response for high-viscosity liquids: Thanks to unique formulation and design technology, even cream and gel-like liquids are instantly sealed by the rubber's restoring force, contributing to shorter takt times. - Improved cleanability (CIP/SIP): Designed to minimize dead spaces, allowing cleaning solutions to reach every detail easily, thereby reducing the risks of microbial growth and residual components.

[Delivery Example] Special Response for Dual Plate Check Valve

[Delivery Example] Special Response for Dual Plate Check Valve

Our skilled team of engineers will carefully manufacture check valves tailored to your specifications, considering the material, size, shape, valve box, and strength of the valve body.

Introduction of special cases for dual plate check valves. A check valve (non-return valve) is a valve installed downstream of pressure-generating devices such as pumps to prevent backflow. The valve body opens due to fluid pressure or flow rate, and closes due to a decrease in pressure or flow rate, preventing backflow through spring torque. [Contents (excerpt)] ■ Maximum nominal diameter 1350A Delivered a stainless steel valve with a nominal diameter of 1350A to a seawater desalination plant in the Middle East. * It is also possible to manufacture valves with a nominal diameter of 1350A or larger.
