The Throttle (Needle) Valve PP is a precision flow control device designed for accurate regulation of fluid or gas flow in clean environments. It features a needle-style valve mechanism that allows fine-tuned adjustment of flow rate, making it ideal for applications requiring precise throttling, such as in process control systems, laboratory equipment, or pneumatic circuits where consistent flow management is essential.
The body and main structural components are manufactured from polypropylene (PP), a material selected for its excellent chemical resistance, high transparency, and suitability in clean environments. The primary metal parts, including valve stems and fittings, are made from SUS304 stainless steel, providing strength and durability in chemical or corrosive atmospheres. All flow path components are constructed without any copper-based metallic materials to ensure compatibility with non-copper systems and prevent contamination.
The valve is available in multiple connection types including metric male threads (M5x0.8) and taper pipe male threads (R1/8, R1/4, R3/8, R1/2), enabling integration into a wide range of piping systems. The threaded connections are designed for secure alignment and reliable sealing under operational conditions.
The valve operates within a maximum pressure rating of 1.0MPa (at 0 to 20℃) and can handle a maximum vacuum of -100kPa. It is rated for an operating temperature range of 0 to 80℃ under standard conditions; when equipped with the Sealock feature, the temperature limit is reduced to 0 to 60℃. The seal materials vary by model: HNBR or FKM are used in low-concentration ozone environments, while EPDM is employed for applications requiring excellent weather and cold resistance—though caution is advised due to its lower resistance to mineral oils.
Available in a range of sizes including φ4, φ6, φ8, φ10, and φ12 mm (equivalent to φ1/4, φ3/8, φ1/2 inches), the valve offers flexibility for different system requirements. All variants are available in standard configurations with no color options specified.
The valve is designed for direct integration into existing systems via its threaded interfaces. The M5x0.8 metric male thread and taper pipe threads (R1/8, R1/4, R3/8, R1/2) provide clear installation points that align with standard industrial fittings, ensuring compatibility during system assembly or retrofitting.
