Low Resistance Dashpot Check Valve is installed on pump outlet, it can protect medium reversing and
eliminate occurrence of destroyed water hammer effectively when pump is normal stop or suddenly stop due to electricity accident. It’s applied to the low consistency dross of rising, raw water and sewage.
1．The valve can run automatically without drive and operating system after setting the parameters. According to state of the pump open and close, it can actualize slow open, full flowing, quick close, slow close to check and other functions by using pressure change of own medium as the drive force.
2．The closing angle and the close time can be adjustable, so that the valve can be suitable for various operating conditions.
3．Slanted seat, the open and close journey is short. (open and close angle is 77 degree). excellent on and off operation performance.
4．Large offset double eccentric disc design and slanted seat, when the valve open and close, sealing couple move relative that is similar to cam gear and release abrasion between seat and disc. long working life.
5．Hydraulic damping device make up of damping oil jar and oil cup, without external pipe, no need of supplying pressure by hydraulic station.
