Home > Stainless Steel Needle Valves
Weston Stainless, Midland, UK is a reliable manufacturer and supplier of precision-engineered stainless steel valve solutions. Renowned for delivering excellence in various industries. Our Stainless Steel Needle Valves are designed using high-quality materials. Providing excellent corrosion resistance, durability and pressure performance. With a thin tapered needle-point plunger design these valves offer accurate control of flow and are best suited for high-accuracy applications. Their heavy-duty construction and space-saving designs makes them ideal for application in chemical, oil & gas, instrumentation and high-pressure fluid systems.
Stainless Steel Needle Valves are typically constructed from high-quality stainless steel known for its excellent strength, durability, and resistance to corrosion. Chromium (18–20%), Nickel (8–14%) and Molybdenum (2–3%) for outstanding corrosion and chemical resistance. These valves have high mechanical properties such as tensile strength of 515–620 MPa, yield strength of 205–290 MPa and good elongation (30–40%). They have a density of 7.9 g/cm³ and a melting point of approximately 1400°C and they provide good thermal conductivity and high-pressure capability. Their fine-thread stem design provides precise, leak-free flow control in precision-oriented fluid and gas applications.
