Founded in 2020 and located in Wenzhou, Zhejiang, KLV specializes in the R&D of power plant valves. It has developed a light-torque high-temperature high-pressure stop valve that reduces opening and closing torque by approximately 70% compared to conventional designs, offering reliable sealing and high sensitivity. The forged valve is lightweight and easy to maintain; the large-diameter high-pressure valve features an impact handwheel and a pressure-self-sealing structure, facilitating convenient disassembly/assembly and ensuring safe, reliable operation. KLV has supplied supporting valves for 300MW and 600MW subcritical units. Its main products include high-temperature high-pressure stop valves, gate valves, check valves, and other series for power plant applications.
