The Speed Control Valve SUS316 is a precision flow control device designed to regulate air flow in industrial systems. Its primary function is to provide smooth and reliable adjustment of airflow speed, ensuring consistent performance under varying operational conditions. The valve features a lock-claw mechanism that ensures excellent operability when releasing the tube, allowing for precise positioning and secure disengagement during maintenance or operation.
The valve is constructed entirely from SUS316 stainless steel for all main metal components, offering superior corrosion resistance in harsh environments. This material selection ensures long-term durability and performance even when exposed to aggressive media. The seal materials are either HNBR or FKM rubber, both of which provide enhanced ozone resistance—HNBR with improved resistance due to hydrogen addition to NBR, and FKM delivering outstanding heat, chemical, and ozone resistance. No copper-based metallic material is used in the flow path, ensuring compatibility with non-copper systems.
The valve offers multiple connection options including metric male threads (M5x0.8) and tapered pipe male threads (R1/8, R1/4, R3/8, R1/2), allowing for flexible integration into a wide range of piping configurations. These interfaces ensure secure and leak-free connections across different system designs and equipment types.
The valve is engineered to operate within an air medium under a pressure range of 0.1 to 0.9 MPa, with a temperature range from -5°C to 60°C (no freezing). The valve seat cracking pressure is rated at 0.05 MPa, indicating robust performance under normal operating conditions and resistance to mechanical stress. It is specifically designed for low-concentration ozone environments where HNBR or FKM seal materials are used to maintain integrity.
Available in a range of metric sizes including φ4, φ6, φ8, φ10, φ12, and φ16 mm, the valve provides scalable options to match different system requirements. All variants are offered without color variation, as the product is designed for functional performance rather than aesthetic features.
Installation requires alignment with compatible piping systems using either M5x0.8 metric threads or R1/8 through R1/2 tapered pipe threads. The valve is delivered in a clean-room package, sealed with fluorine grease and cleaned under clean air conditions to ensure no contamination during handling or assembly. No lubrication is used during assembly, meeting non-grease oil-free specifications for use in sensitive environments.
