Ball check valve – Series B6 70

Ball check valve ensuring the protection of the pumps against flow inversion.

Applications :

•  Pumping stations for sewage water and loaded or viscous fluids.

Product benefits :

• Full bore ensured by total clearance of the ball, preventing any risk of clogging.
• Low head loss due to full bore.
• Self cleaning ball, guided by the flow up to its lateral housing, then it moves aside.
• Sealing, even with low pressure, obtained by a ball fully encapsulated in moulded elastomer, in horizontal or ascendant vertical mounting.
• NBR seat buitl in the valve body
• Resin ball, aluminium or ductile iron, fuly encapsulated in moulded elastomer.
• Removable bonnet version (Types 17 and 16) or removable seat version (type 18), enabling the replacement of the ball.

Flanged version (Type 16):

•       DN 40 to 150 PFA16
•       DN200 to 400 PFA10

Threaded version (Type 17):
