Sewages Ball Retention Valve
Model: RB, DN 50 a 500; PN 10 | Brand: Eathisa
The clapper check valves are not elements thought to be used in sewages, because this type of fluids are characterized by carrying solids and other types of elements in suspension. All this elements block the clap at the closing moment. Even they are tangled in the restraints and other elements avoiding its right functioning.
DESIGN
The design of this check ball valve is characterized by do not carry any type of articulation, but it has a totally free movement.
As it does not have articulations, it does not produce dead spaces where impurities are accumulated and polymerized.
As it does not have articulations, it does not produce dead spaces where impurities are accumulated and polymerized.
THIS ENSURES THAT
• As it does not have articulations or metallic elements, the solid drags and viscosities can not be blocked or adhered.
• At the closing moment, if the ball comes up against some obstacle, this will made the balll spins passing in this way the solid, closing in the presence of solids without difficulty.
• A watetight sealing, because of this one is produced between the elastomeric coating ball and the metallic seat.
