k. ZMK/ ZNK/ ZKK HIGH PRESSURE CONTROL VALVE

This series is a successful self-research product, mainly to meet the need of the power plant, especially for **0/**0MW 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)*0~**0 (3/4"~*0″) ; PN?MPa?1.6\4.0\6.4\*0.0 ?ASME Class **0/**0/**0/**0?;.

Working temperature: **0~**0celsius. Flow characteristic: equal percent, linear.
?
The key technology of ZKK ZNK-type high-pressure regulating valve is the inside valve trim structure and its manufacturing technics. (Figure 1)

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.
