Product Overview
HH44T/X/H micro resistance slow closing check valve for water supply and drainage pipeline installed in the outlet of the water pump to prevent media counterflow and eliminate destructive waterhammer, and can effectively reduce the pressure of the valve to close water hammer, can ensure the safe operation of the pipe network. It has the characteristics of light valve disc, large opening, remarkable power saving effect, small fluid resistance, novel design of water hammer elimination mechanism, stable and reliable sealing performance, wear resistance, long service life, smooth operation, no vibration, no noise, etc.
Structural Characteristics
- The structure length is short, and its structure length is only 1/4 ~ 1/8 of the traditional flange check valve
- Small volume, light weight, its weight is only 1/4 ~ 1/20 of the traditional micro resistance slow closing check valve
- The valve disc closes quickly and the water hammer pressure is small
- Horizontal or vertical pipes can be used and installed conveniently
- Small flow resistance
- Sensitive action and good sealing performance
- The stroke of valve disc is short and the impact force of closing valve is small
- Overall structure, simple and compact, beautiful appearance
- Long service life and high reliability
