High Pressure Control Valve ZMK/ ZNK/ ZKK

1) This series is a successful self-research product, mainly to meet the need of the power plant, especially for 300/600MW large-scale thermal power generation equipment, oil and chemical plant. There are ZMK(pneumatic high pressure regulating valve), ZKK(electric high pressure valve), ZNK(high pressure regulating by hand). DN(mm)20~250 (3/4"~10″) ; PN(MPa)1. 6\4. 0\6. 4\10. 0 (ASME Class 150/300/400/600);. Working temperature: 250~400℃. Flow characteristic: equal percent, linear.
2) The key technology of ZKK ZNK-type high-pressure regulating valve is the inside valve trim structure and its manufacturing technics. (Figure 1)
3) According to the spot condition, there are two types of trim are available, full-stack-plate valves (Figure 1) and the other one is stack plate and the window-shaped sleeve of the modular structure (Figure 2). Two kinds of structural forms, the former is applied in high-pressure differential occasions system such as the power plant or chemical industry and high-pressure differential occasion upon small opening. The latter in medium and high pressure occasion upon normal opening when pressure differential is not large.
4) Anti-air erosion of high-pressure differential control valve body (Figure 3)
