Description
This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. It is an automatic valve. It is applicable to industrial and domestic sewage pipe networks with high viscosity and suspended solids
Main Features
▪ Size range: up to DN400; Pressure range: up to 16bar
▪ Self-cleaning, no risk of impurities getting stuck on the ball.
▪ Silent closing, no water hammer to reduce the damage to the pipeline system during valve closing
▪ 100% testing before packing and delivery
▪ full bore, 100% flow area, full waterway and low flow resistance for low headloss
▪ suitable for Horizontal or vertical installation
▪ Compact design maintains easier installation.
▪ Light weight design for easy installation
▪ Self-cleaning sinking nitrile coated ball
▪ Eliminates the risk of impurities getting stuck on the ball.
▪ Low pressure drop
