Purpose and functions:
The Swing Check Valve, is used to prevent the backflow of the medium in the pipeline. The opening and closing parts are automatically opened or closed by the flow and force of the medium to prevent the backflow of the medium. The check valve belongs to the automatic valve class, which is mainly used on the pipeline with one-way flow of the medium, and only allows the medium to flow in one direction to prevent accidents.
The Swing Check Valve is suitable for nominal pressure PN1.0MPa~42.0MPa, Class150-2500; Nominal diameter DN15~1200mm, NPS1/2~48; The operating temperature of -196~540℃ of various pipes, used to prevent the backflow of the medium. Through the selection of different materials, it can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media.
It can be widely used in tap water, sewage, construction, petroleum, chemical industry, textile, electric power, shipbuilding, metallurgy, and energy systems. Used as a regulating and intercepting device on fluid pipelines
Design Standards:
Structure length: API594, API6D, DIN3202, JB/T8937.
Pressure-temperature class: SNSIB16.34, DIN2401, GB/T9124, HG20604, HG20625, SH3406, JB/T74.
Test and inspection: API598, JB/T9092.
Piping flange: JB/T74~90、GB/T9112!9124、HG20592~20635、SH3406、ANSIB16.5、DIN2543~2548、GB/T13402、API605、ASMEB16.47
Valve Characteristics:
The structural length is short, and the structural length is only 1/4 to 1/8 of the traditional flange check valve.
Small size, light weight, and its weight is only 1/4 to 1/20 of the traditional micro-retarding check valve.
The valve disc closes quickly and the water hammer pressure is small.
Horizontal or vertical pipes can be used, easy to install.
Smooth flow channel, low fluid resistance.
Sensitive action, good sealing performance.
Short stroke of valve disc, small impact of closing valve.
Overall structure, simple and compact, beautiful shape.
Long service life and high reliability.
