Focusing on the research and development, production, and sales of copper valves
Swing type (horizontal): The valve disc rotates around the rocker arm (pin shaft). When the medium flows forward, the valve disc opens, and when it flows backward, the valve disc closes under its own gravity and reflux pressure.
Lift type (vertical): The valve disc slides along the vertical centerline of the valve body. Relying on the combined action of medium pressure and built-in springs to open and close.
You specify the brass — CW617N, Hpb59-1 or lead-free DZR. We verify every incoming batch with optical emission spectrometry before it reaches the production floor. Material compliance is checked at the source, not after the fact.
100% Air-Tight.
Selectively Pressure-Tested.
-
No leaks, no exceptions. Every single valve passes a pneumatic tightness test before shipping. Throughout production, our inspectors run first-off checks, in-process spot checks, and final inspection. Hydrostatic pressure testing is done on a batch basis to confirm structural strength.
In-House Lab.
We Test What We Make.
-
We keep quality control under our own roof. Our lab runs a valve lifecycle tester, bending-strength and torsion test rigs, a spectrometer, and more. Material composition, mechanical performance, durability—we verify the numbers ourselves and keep the data on file.
DN8 to DN100.
2,000+ Molds.
-
Ball valves, gate valves, globe valves, check valves— from small DN8 up to DN100. British, American standards, all within our scope. With over 2,000 proprietary molds and flexible production lines, we handle small-batch variety without pushing up your inventory costs.
Delivery Dates.
We Stand Behind.
-
Frequently ordered models are backed by stock for quick replenishment. For custom orders, we keep you updated throughout tooling and production. On-time delivery is a number we track closely and a commitment we take seriously.
Broad Product Coverage.
One-Stop Sourcing.
-
Our manufacturing capabilities span valves, thermostatic valves, manifolds, control panels, angle valves, faucets, and more—covering key components across water treatment and HVAC systems. One supplier, fewer headaches, a smoother project.

FAQ
Q What do you do if there is a quality issue?
AWe offer a 2-year warranty. If a quality issue occurs, our insurance company will provide immediate compensation, and we will replace the product free of charge. We also collect and analyze the cause of the problem to ensure it does not happen again.
Q How do you ensure product quality?
AEvery batch of raw material is inspected using a spectrometer. Each production process is checked, and every finished product undergoes 100% air tightness testing before shipment to ensure high quality.
Q Can you provide OEM/ODM customization?
A
Yes, we have professional R&D engineers who can develop and mass-produce products based on customer drawings or samples.
