How to Choose Brass Ball Valves and Avoid Pitfalls: Yuanlun Teaches You to Pick the Truly Reliable "Waterway Guardian"
Brass ball valves are "key small components" in household water systems, but the price range from 1 RMB to 50 RMB on the market hides many "zinc alloy traps." In fact, choosing the right copper ball valve isn't difficult-take Yuanlun brass ball valves as an example. From material to performance, a truly well‑made product carries its own "trustworthy label."
1. Material Verification: Three Tricks to Spot "Fakes," Yuanlun is the "Genuine Copper Benchmark"
Weight + Magnet Test:
A Yuanlun DN15 brass ball valve weighs ≥200 g (far exceeding the 180 g genuine copper standard) and feels solid in hand. When a magnet is brought close, the valve body shows no attraction (eliminating zinc‑alloy impurities containing iron).
Detail Markings:
Yuanlun valve bodies are clearly stamped with copper grade codes, and the port threads are precise without burrs. Common defects in inferior products such as broken threads or misaligned teeth are completely absent.
Burn Test:
When scorched, a Yuanlun copper ball valve only oxidizes and turns black, without a pungent odor. In contrast, zinc‑alloy imitations emit white smoke and a sour smell-this is also why Yuanlun insists on using high‑purity brass.
2. Performance Parameters: Yuanlun's Label Contains the "Safety Code"
The specifications of a qualified brass ball valve are an "invisible guarantee." Yuanlun brass ball valves' labels are filled with safety assurance:
①Pressure rating PN16 (withstanding 1.6 MPa), providing 3 times the safety margin over municipal water supply pressure.
②Operating temperature -25 ℃ to 160 ℃, covering all scenarios from household water supply to underfloor heating hot water.
③Certified with both the GB/T 8464 national standard and potable water safety certification, making it safe even for direct‑drinking water pipelines.
3. Installation Tips: Yuanlun + Correct Operation = 10+ Years of Extra Service Life
Choosing the right product also means installing it correctly:
①Yuanlun valve bodies have clear arrows indicating flow direction. Installing it backwards can reduce flow by 30%, so alignment is essential.
②When wrapping Teflon tape, follow Yuanlun's guidance: "wrap counter‑clockwise 5‑8 turns," combined with precise threading to prevent side leakage.
③Yuanlun valve handles are designed with operational clearance in mind. For DN20 models, only an 8 cm radius is needed for smoother on/off operation.
Q&A: Common Questions about Yuanlun Brass Ball Valves
Q1: Can Yuanlun brass ball valves be used in underfloor heating systems?
A: Absolutely! Their temperature resistance range of -25 ℃ to 160 ℃ allows stable compatibility with underfloor heating hot‑water circulation, with no deformation under high temperatures.
Q2: What is the warranty period for Yuanlun brass ball valves?
A: Yuanlun brass ball valves come with a 2‑year warranty. Thanks to their solid material and craftsmanship, their actual service life far exceeds 2 years.
When choosing a brass ball valve, don't just look at the price-products like Yuanlun, made with genuine materials, are both a "little guardian" for your water system and a "worry‑free choice" for long‑term use.
