Micro Resistance Slow Closing Check Valve
Product overview
HH44X/T/H Micro resistance slow closing check valve is used for water supply and drainage pipeline, installed at the outlet of water pump, to prevent medium backflow and eliminate destructive water hammer, effectively reduce the pressure of valve closing water hammer, and ensure the safe operation of pipe network.It has the characteristics of light disc, large opening, remarkable power saving effect, small fluid resistance, novel design of water hammer eliminating mecha-nism, stable and reliable sealing performance, wear resistance, long service life, stable operation, no vibration, no noise, etc.
Product Features
1. The structure length is short, and its structure length is only 1 / 4 ~ 1 / 8 of the traditional flange check valve
2. Small volume, light weight, its weight is only 1 / 4 ~ 1 / 20 of the traditional micro resistance slow closing check valve
3. The valve disc closes quickly and the water hammer pressure is small
4. Horizontal or vertical pipes can be used and installed conveniently
5. The flow channel is unobstructed and the fluid resistance is small
6. Sensitive action and good sealing performance
7. The stroke of valve disc is short and the impact force of closing valve is small
8. Overall structure, simple and compact, beautiful appearance
9. Long service life and high reliability
