Product Details

Product Formation

Our Brass Magnetic Locking Ball Valve is a high-durability fluid control component designed for professional pipeline systems. Crafted from premium RHPb59-1 brass (corrosion-resistant, high-strength), it features a secure magnetic multi-pole locking mechanism—only operable with a dedicated magnetic key, effectively preventing unauthorized adjustment or tampering.

With a nominal diameter of DN32 (1 1/4") and a working pressure rating of PN16 (1.6MPa), it’s suitable for non-corrosive media (cold/hot water, gas, oil) in temperatures ranging from -20℃ to 120℃. The female thread connection (ISO 228/GB/T 8464 compliant) ensures easy, leak-tight installation, while EPDM/PTFE seals guarantee long-term sealing performance.

Product Features

1. Secure Magnetic Locking Design

Adopts a professional secure magnetic locking mechanism that operates exclusively with a dedicated multi-pole magnetic key. The multi-pole magnetic configuration features precise pole position matching, which means only the key with the exact magnetic pole distribution can activate the locking core and drive the valve adjustment. This design effectively blocks all unauthorized adjustment, malicious tampering, or theft behaviors—such as random opening/closing by irrelevant personnel, intentional damage to the valve structure, or theft of internal components. It is particularly ideal for pipeline management scenarios that require high security, including public infrastructure pipelines (municipal water supply and drainage, gas transmission), industrial park dedicated pipelines, and private key pipeline sections (residential community central heating, enterprise internal fluid transmission), ensuring the stability and safety of the entire pipeline system.

2. High-Durability Brass Construction

The main body is crafted from premium RHPb59-1 brass, a high-performance alloy with a copper content of approximately 59% and a lead content of 1%. This material boasts excellent anti-corrosion properties, capable of resisting erosion from moisture, oxygen, and most non-corrosive fluids in the pipeline, effectively preventing rusting, oxidation, and structural damage. Meanwhile, it has high tensile strength and good mechanical toughness, enabling it to withstand the pressure impact during pipeline operation and avoid deformation or cracking. Even in harsh fluid environments—such as pipelines containing trace impurities, alternating cold and hot fluid circulation, or outdoor exposed installation environments with large temperature differences—the product can maintain stable performance, ensuring a long service life of no less than 10 years, greatly reducing the frequency of maintenance and replacement, and lowering the overall operation cost.

3. Reliable Sealing Performance

Equipped with high-quality EPDM (Ethylene Propylene Diene Monomer) or PTFE (Polytetrafluoroethylene) sealing components, which are carefully selected based on different application scenarios. EPDM seals excel in excellent aging resistance, weather resistance, and good elasticity, while PTFE seals feature superior high-temperature resistance, corrosion resistance, and low friction coefficient. Both types of seals can achieve reliable leak-tightness up to PN16 pressure class (equivalent to 1.6MPa working pressure), completely avoiding fluid leakage in the pipeline. In addition, the product maintains stable sealing performance in a wide temperature range of -20℃ to 120℃, whether in cold northern winter or high-temperature industrial fluid transmission, it can ensure tight sealing and safe operation.

4. Standardized & Easy Installation

Adopts a female thread connection mode that fully complies with international standard ISO 228 and national standard GB/T 8464. The standardized thread design ensures perfect compatibility with most universal pipeline parts on the market, such as pipe fittings, connectors, and adapters of the same specification, eliminating the trouble of finding special matching accessories. The installation process is simple and efficient, requiring no complex professional tools—only common wrenches are needed to complete the assembly. There is no need for additional adapter components or tedious adjustment steps, which not only shortens the installation time but also reduces the difficulty of construction. It is suitable for both professional construction teams and on-site maintenance personnel to carry out quick installation and replacement work.

5. Versatile Application Compatibility

With strong adaptability, the product is suitable for conveying various non-corrosive media, including cold water (such as tap water, cooling water), hot water (such as central heating water, industrial process hot water), gas (such as natural gas, liquefied petroleum gas, compressed air), and oil (such as lubricating oil, hydraulic oil, light fuel oil). Based on its excellent performance, it can be widely applied to multiple scenarios, including HVAC systems (air conditioning water circulation, floor heating pipeline control), urban and residential water supply systems (water meter front and rear control valves), gas transmission pipelines (household gas terminals, commercial gas equipment connections), and industrial light fluid transmission systems. It can meet the different usage needs of civil, commercial, and industrial fields.

6. Precise Flow Control

Adopts a full-bore ball core design, which maximizes the inner diameter of the fluid channel, minimizing flow resistance during fluid transmission. This design not only ensures efficient fluid circulation and improves transmission efficiency but also avoids the accumulation of impurities in the pipeline, reducing the risk of pipeline blockage. The ball core adopts a 90° rotation switching structure, which has the characteristics of flexible operation and quick response—only a 90° rotation of the valve stem can complete the switching between full opening and full closing. In addition, the precise processing of the ball core and valve seat ensures accurate flow regulation. During the adjustment process, the flow can be linearly controlled according to the actual demand, realizing fine management of fluid flow. It is suitable for scenarios that require precise control of fluid flow, such as industrial process fluid regulation, precision instrument cooling systems, and intelligent water supply control.
