Single-seat pressure reducing valve, size DN20~DN150 (NPS 3/4~NPS 6), pressure class PN25~PN100 (Class 150~Class 600). Choose different valve body materials based on temperature: WCB, ZG20CrMo (WC6), ZG15Cr1Mo1V (WC9), etc., to suit various operating conditions and control steam pressure.

The valve disc structure features a single seat design, which minimizes leakage, offers a wide adjustment range, and ensures more precise steam regulation with a simple structure and low failure rate. The valve stem and seat are sealed with a conical surface, utilizing a hard alloy for the sealing surface, with a standard leakage rate of V grade.
