Features
1.Excellent Corrosion Resistance and Hygiene Performance:Key components such as the valve body and bonnet are cast from high-purity copper alloy, which inherently resists corrosion and inhibits bacterial growth. This makes it particularly suitable for water supply, HVAC, and food-grade piping systems, ensuring long-term rust-free operation and maintaining medium purity.
2.Reliable Sealing and Durable Design:The valve disc and seat sealing pair feature a precisely ground conical or planar structure, combined with elastic gaskets or copper alloy self-sealing designs. This ensures tight shutoff under medium-to-low-pressure conditions, offering excellent resistance to erosion and wear for extended service life.
3.Lightweight and Compact Structure:The all-copper construction significantly reduces valve weight compared to cast iron or stainless steel valves of the same specifications, making installation and handling easier. The internal thread connection eliminates the need for flanges, resulting in a compact design suitable for space-constrained pipeline layouts.
4.Superior Thermal Conductivity and Freeze Resistance:The high thermal conductivity of copper alloy allows rapid equalization of localized temperature variations, minimizing sealing stress caused by temperature differences. It also provides some resistance to freeze expansion in cold environments, making it suitable for chilled water, refrigeration, and similar systems.
5.Flexible Operation and Easy Maintenance:The lightweight handwheel drive mechanism requires minimal torque for opening and closing, while the stem’s vertical movement provides intuitive and precise control. The simple stuffing box design allows for quick adjustment of the gland or replacement of standard packing to address minor leaks, ensuring low maintenance costs.
6.Cost-Effective and Broad Compatibility:More economical than stainless steel valves, it offers a high cost-performance ratio. Compliant with universal pipe thread standards (e.g., G, R), it can be directly connected to common copper pipes, galvanized pipes, or plastic fittings. Widely used in residential buildings, agricultural irrigation, small industrial equipment, and similar applications.
7.Versatile Media Suitability:Suitable for water, steam, oil, air, and non-corrosive liquids or gases. The operating temperature range covers standard residential and general industrial needs (-20℃ to +200℃), with pressure ratings meeting mainstream pipeline standards.
8.Standardized Design and Comprehensive Certifications:The valve design and manufacturing comply with national valve standards (e.g., GB, JB). Materials meet hygiene and environmental requirements, and drinking water safety certifications (e.g., NSF/WRAS) can be provided as needed to satisfy various industry regulations.
