The Speed Controller PP is a precision flow control device designed to regulate and manage fluid or air flow in clean environment applications. It features an integrated check valve mechanism that ensures unidirectional flow while maintaining system efficiency. This product is ideal for use in environments where contamination must be minimized, such as pharmaceutical, food processing, or semiconductor manufacturing systems.
The body and main resin components are constructed from polypropylene (PP), selected for its excellent chemical resistance, high transparency, and suitability in clean environments. Critical metal parts, including structural supports and fittings, are made from SUS304 stainless steel, providing durability under mechanical stress and exposure to chemical atmospheres. The seal rubber is composed of EPDM, offering superior weather, cold, and ozone resistance—though caution is advised due to reduced resistance to mineral oils.
The Speed Controller PP connects via multiple interface options including metric male threads (M3x0.5, M5x0.8) and tapered pipe male threads (R1/8, R1/4, R3/8, R1/2). It is also available in standard sizes with a nominal diameter ranging from φ4 to φ12 mm, corresponding to inch sizes of φ1/4 to φ1/2. These configurations allow for flexible integration into various piping and system designs.
The device operates within a pressure range of 0.1 to 1.0 MPa (at 0 to 20℃), or alternatively 0.05 to 0.5 MPa or 0.05 to 1.0 MPa under the same temperature conditions. The check valve opens at pressures of 0.05 MPa, 0.02 MPa, or 0.005 MPa depending on model configuration. Operating temperatures range from 0 to 80℃ in standard use; when equipped with Sealock technology, the maximum operating temperature is limited to 0 to 60℃. The product is designed for non-freezing conditions in all applications.
Available in a range of sizes including φ4, φ6, φ8, φ10, and φ12 mm (equivalent to φ1/4, φ3/8, φ1/2 inches), the Speed Controller PP offers multiple options to match specific system requirements. All variants are available in a clean-room packaged configuration, ensuring no contamination during storage or handling.
The Speed Controller PP is designed for direct integration into piping systems using standard metric or tapered pipe threads. No copper-based metallic materials are present in the flow path, ensuring compatibility with non-corrosive and oil-free environments. Assembly is performed without lubrication—non-grease, oil-free specifications are maintained throughout manufacturing. After final cleaning with clean air, the product is sealed in a clean-room environment using fluorine grease for bearing lubrication.
