Micro Resistance Slow Closing Check Valve
Introduction:
Micro resistance slow closing check valve is applicable to nominal pressure PN1.0MPa~42.0MPa, Class150-2500; Nominal diameter DN15~1200mm, NPS 1/2~48; On various pipelines with operating temperature of 196~540 ℃, it is used to prevent medium backflow. By selecting different materials, it can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium, urea and other media.
Product features:
The valve is mainly composed of valve body, valve cover, valve plate, counterweight, piston and regulating valve. It is used for water supply and drainage pipeline and installed at the pump outlet to prevent medium countercurrent and fire destructive water hammer. It has the advantages of light valve disc, large opening, significant power saving effect, small fluid resistance, reasonable water hammer elimination structure, reliable sealing performance, wear resistance, long service life, stable operation, no vibration, no noise, etc.
Applicable media: water, oil, seawater, sewage
Applicable temperature: 0~80 ℃ (up to 200 ℃ if necessary)
