When the head from the drainage hole to the water level is small, the effectiveness is doubled! A check valve for retaining walls using a float ball.
The "YS50" is a float-type weep hole that ensures a strong and reliable seal on the valve seat due to the buoyancy of a special elastic float, eliminating concerns about water leakage. During dry conditions, the float completely detaches from the valve seat, allowing groundwater to be freely discharged. Since the valve seat is oriented downward, there is no risk of mud settling and hardening near the valve seat. Additionally, the operating components are built into the drainage pipe, preventing damage from impacts caused by flowing debris and theft due to vandalism. 【Features】 ■ Reliable valve operation ■ No negative pressure during groundwater discharge ■ No mud accumulation or adhesion ■ No risk of damage or theft ■ The elasticity and strength of the float and valve seat are stable with respect to temperature *For more details, please refer to the PDF document or feel free to contact us.
