Introduction to 201 Stainless Steel Angle Valves
A 201 stainless steel angle valve is a commonly used pipe fitting in water systems, primarily designed to control water flow direction, regulate flow rate, or open/close pipelines. Below is a detailed introduction:
201 Stainless Steel: Belongs to the chromium-manganese-nickel series of austenitic stainless steel, featuring the following characteristics:
Corrosion Resistance: Better than cast iron and copper alloys but inferior to 304/316 stainless steel (especially prone to rusting in chloride environments).
High Strength: More durable than plastic angle valves with strong pressure resistance.
Cost-Effectiveness: Priced lower than 304 stainless steel, making it suitable for budget-conscious applications.
Compatible Media: Cold and hot water (note that high temperatures may accelerate corrosion).
Connection Method: Typically internal threads (e.g., G1/2, G3/4) for easy pipeline connection.
Sealing Materials: The valve core is usually ceramic for excellent sealing and wear resistance; gaskets may be made of rubber or silicone.
Surface Treatment: Brushed or polished for a shiny appearance, but regular cleaning is required to prevent rust stains.
Short-Term Use: Such as temporary projects or low-cost renovation work.
Low-Corrosion Environments: Dry regions or households with good water quality (avoid coastal, high-humidity, or acidic/alkaline environments).
Non-Critical Areas: Non-potable water pipelines (e.g., irrigation, drainage), as 201 stainless steel may release trace heavy metals.
