Sleeve调节阀, size DN20~DN100 (NPS3/4~NPS4), pressure class PN25~PN100 (Class 150~Class 600). Available in various valve body materials according to customer requirements: 20, 304, etc., to suit different operating conditions and control the flow of reducing water.

The regulating valve features a sleeve structure, which minimizes noise, offers a wide adjustment range, and provides more precise control over the reduced temperature water. It also filters out impurities, preventing them from entering the downstream, and protects the sealing surfaces. The sleeve-type regulating valve is the mainstream product in the current market. The valve core and seat are sealed with a conical surface and coated with cobalt-based hard alloy. All internal valve components have been modularized for quick disassembly, resulting in minimal unbalanced forces, a tunable ratio of 20:1, smooth operation, and no jamming or sticking.
