Zubi T115AR – Ball Type Non-Return Valve
The Zubi T115AR is a flanged ball check valve with a self-cleaning geometry, designed for water, wastewater, and low solids-content liquids. The ball rotates during operation, minimizing the risk of solids accumulation on the sealing surface. No actuator is required for operation.

- DN125–DN250: GG25 with NBR coating
Resin balls are supplied without rubber coating.
Applications
Suitable for wastewater, process water, low solids-content liquids, and pipelines requiring full bore flow without dead zones for solids accumulation. For slurry, chemicals, or seawater, verify body, lining, and ball material compatibility.
Standards / Compliance
Complies with PED 2014/68/EU (Fluid Group 1(b), 2, Category I Module A) and ATEX 2014/34/EU for Area 2 & 22.
FAQ
When is a ball check valve preferred over a swing check?
When suspended solids or risk of deposits are present in the medium.
What should be checked before selection?
DN, available differential pressure, solids concentration, body material, lining, and NBR compatibility with the process fluid.
