Plastic swing check valve
The RSK-type swing check valve is a wafer type that is installed between flanges. It has a small face-to-face dimension and is lighter than metal types, making the piping compact and easy.
Metal swing chuck valve
The ZRSK type swing check valve is a wafer type that is installed between flanges. Due to its small face-to-face dimension, the piping space becomes compact.
3A certified. Finish of the wetted parts: 32Ra/0.8μm.
FB6903 is necessary to protect products from backflow. The valve remains open due to the forward flow of fluid. If the flow is interrupted, the plug is pressed against the seat by a spring, causing it to close due to backflow. This valve is used in many sanitary applications and is a 3A certified product in accordance with the 58-01 standard. <Specifications> - Connection diameter: 1/2" to 4" - Connection type: Sanitary clamp - Body style: 3-piece - Body material: 316SS - Seat material: EPDM or Viton - Metal surface finish: Wetted parts 32Ra/0.8μm or further treatment - Pressure rating @ room temperature: 0.966MPa - Industrial standards and testing: 3A certification - Cracking pressure for 1/2" and 3/4": < 0.069MPa - Cracking pressure for 1" to 4": < 0.035MPa *For more details, please contact us or download the catalog.
This is a check valve used for the discharge pump of a purification tank to prevent backflow. It comes with a union for easy removal of the pump. The body is made of PVC.
- Connection diameter: Compatible with 40A/50A types Connection is easy by simply gluing PVC pipe VP40 to the sockets on both sides. If connecting PVC pipe VP50, you can use a TS socket 50A (sold separately) glued to the receiving end. * There is also a connection diameter: 30A type available (for PVC pipe VP30). - Structure with a union for easy pump removal The main body has a flexible union, allowing for easy removal by loosening the bag nut. - Compact design The main body is compactly designed, making it possible to install in narrow piping spaces. - The main body is made of polyvinyl chloride (PVC) Being made of resin, there is no concern about rust. Additionally, due to being made of PVC, it also has excellent chemical resistance.
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
