Someone managing a network of older apartment buildings will tell you the real pain isn’t the valve failing—it’s the threads stripping when you try to replace it, and that’s where we see people come back for these because the HPb59-1 body holds up over years of thermal cycling, and teh CW617N ball itself gives you that extra corrosion resistance you want if there’s any scale in the water.
You’re looking at a PN rating that runs form 1.0 all the way up to 32.0MPa depending on the size, with the smaller DN15 and DN20 sizes handling the higher end of that range typically, and straight-through design means you’re not losing much pressrue even when you’re pushing 150°C through it—just keep in mind the oil seal is what does the heavy lifting here for sealing, not a PTFE seat, so it’s better for continuous flow than for systems that cycle open and closed every few minutes.
Basically, it’s threaded male and female on both ends, so you can drop it into an existing line without adapters if you stick to the common DN15 through DN50 sizes, and we usually stock the iron handle versions by the pallet—the aluminum handle is lighter but honestly most buyers go with iron because of that it stands up better if someone uses a wrench on it.
Not ideal for systems with aggressive chemicals or where you need full port—this is standard port, so there’s a slight restriction inside that doesn’t matter for 99% of water and oil lines but will annoy you if you’re pushing high-viscosity stuff.
Lead time is about 20 days or so on custom labeling or if you need a specific handle color, but for plain bulk orders we usually have stock in the DN15 and DN20 sizes, so it depends on your MOQ.
Anyway, the paperwork is straightforward—COA with every lot, and our company can include SDS if your compliance team asks, just confirm at order time.
HPb59-1 is a leaded brass commonly used in China for good machinability and strength, while CW617N is a European standard for hot-forged brass with high corrosion resistance. We use HPb59-1 for the body to keep costs down and CW617N for the ball to ensure a tight seal and long life in water or oil systems.
Yes, you can specify iron or aluminum handles when ordering. Aluminum handles resist rust better outdoors, while iron handles are stronger but may need a coating to prevent corrosion in wet conditions.
We provide a material test certificate for the brass, a pressure test report for each valve batch, and a certificate of conformance to industrial-grade standards. If you need specific certifications like ISO or CE, let us know and we can arrange them for an extra fee.
Yes, you can mix sizes in a single order. The minimum quantity is typically 100 pieces per size, but for smaller trial orders we can negotiate down to 50 pieces if you cover the setup cost.
Each valve is individually wrapped in poly bags and packed in sturdy export cartons with foam inserts to prevent damage. Custom branding like your logo or color on the handle is available for orders over 500 pieces per size.
