ZMK series of high-performance air defense of the high-pressure differential regulating valve (High-pressure differential regulating valve) is my company after years of experiments, the successful development of a new generation of products. As the relief valve with a new principle of cutting expenditure, unique internal structure, he resolved a large-scale power plant and other industry and the liquid, steam and gas high-pressure differential, high velocity control related problems, such as: space of cavitation , erosion, noise, vibration, and flow characteristics, such as distortion.

High-pressure differential regulating valve spring can be more aerodynamic matching film-implementing agencies, pneumatic piston implementing agencies or electric implementing agencies to meet the requirements of various controlled. Particularly applicable to various types of thermal power plant units by warm water control, the main pump to the minimum flow valve and boiler cycle regulation, and for sewage. After a number of units put into use and the results are quite satisfactory, is the replacement in the field of generation and into the ideal product.
