Rubber Flap Check Valve
The valve is full flow section design with small loss. The sundries can not deposit. It is easy to maintain. The valve is mainly used in water supplying and discharging system. It is installed at the outlet of the pump to prevent the flow
Reverting and water hamper from damaging the pump. It is installed on the by-pass pipe of the inlet pipe in the water pool to prevent the water from flowing back to the system.
